Every four years, it combines all the market leaders in one place and, more than any other industry show, it displays the entire value chain. The complete and innovative range of machinery, products, processes and service gathers exhibitors and trade. This type of welding is frequently used to make vehicles, vessels and pipes as well as in mechanical engineering. Even in shipbuilding, it is difficult to image life without MAG welding. As, due to the fast welding speed, little deformation is to be expected, even in difficult or awkward positions, this arc welding procedure is primarily used for repairs and maintenance of thin metal sheets from 0.6mm thick. The weld is high-strength. Therefore almost no rework is necessary. Welding Wiki: The encyclopedia about welding
Many different energy sources can be used for welding, including a gas flame (chemical), an electric arc (electrical), a laser, an electron beam, friction, and ultrasound. While often an industrial process, welding may be performed in many different environments, including in open air, under water, and in outer space. Welding is a hazardous undertaking and precautions are required to avoid burns, electric shock, vision damage, inhalation of poisonous gases and fumes, and exposure to intense ultraviolet radiation. The term "weld" is of English origin, with roots from Scandinavia. It is often confused with the Old English word, weald, meaning "a forested area", but this word eventually morphed into the modern version, "wild". The Old English word for welding iron was samod (to bring together) or samodwellung (to bring together hot, with "hot" more relating to red-hot or a swelling rage; in contrast to samodfæst, "to bind together with rope or fasteners"). The term "weld" is derived from the Middle English verb "well" (wæll; plural/present tense: wælle) or "welling" (wællen), meaning: "to heat" (to the maximum temperature possible); "to bring to a boil". The modern word was likely derived from the past-tense participle, "welled" (wællende), with the addition of "d" for this purpose being common in the Germanic languages of the Angles and Saxons. It was first recorded in English in 1590, from a version of the Christian Bible that was originally translated into English by John Wycliffe in the fourteenth century. The original version, from Isaiah 2:4, reads, "...thei shul bete togidere their swerdes into shares..." (they shall beat together their swords into plowshares), while the 1590 version was changed to, "...thei shullen welle togidere her swerdes in-to scharris..." (they shall weld together their swords into plowshares), suggesting this particular use of the word likely became popular in English sometime between these periods. wikiHow is a wiki, similar to Wikipedia, which means that many of our articles are co-written by multiple authors.

Copper and its alloys are widely used in. Welding can be dangerous and unhealthy if the proper precautions are not taken. However, using new technology and proper protection greatly reduces risks of injury and death associated with welding. Since many common welding procedures involve an open electric arc or flame, the risk of burns and fire is significant; this is why it is classified as a hot work process. To prevent injury, welders wear personal protective equipment in the form of heavy leather gloves and protective long-sleeve jackets to avoid exposure to extreme heat and flames. Synthetic clothing such as polyester should not be worn since it may burn, causing injury. Additionally, the brightness of the weld area leads to a condition called arc eye or flash burns in which ultraviolet light causes inflammation of the cornea and can burn the retinas of the eyes. Goggles and welding helmets with dark UV-filtering face plates are worn to prevent this exposure. Since the 2000s, some helmets have included a face plate which instantly darkens upon exposure to the intense UV light. To protect bystanders, the welding area is often surrounded with translucent welding curtains. These curtains, made of a polyvinyl chloride plastic film, shield people outside the welding area from the UV light of the electric arc, but cannot replace the filter glass used in helmets.
After welding, a number of distinct regions can be identified in the weld area. The weld itself is called the fusion zone—more specifically, it is where the filler metal was laid during the welding process. The properties of the fusion zone depend primarily on the filler metal used, and its compatibility with the base materials. It is surrounded by the heat-affected zone, the area that had its microstructure and properties altered by the weld. These properties depend on the base material's behavior when subjected to heat. The metal in this area is often weaker than both the base material and the fusion zone, and is also where residual stresses are found. Welding. 160,743 likes · 34 talking about this.

Glass can also be welded to metals and ceramics, although with metals the process is usually more adhesion to the surface of the metal rather than a commingling of the two materials. However, certain glasses will typically bond only to certain metals. For example, lead glass bonds readily to copper or molybdenum, but not to aluminum. Tungsten electrodes are often used in lighting but will not bond to quartz glass, so the tungsten is often wetted with molten borosilicate glass, which bonds to both tungsten and quartz. However, care must be taken to ensure that all materials have similar coefficients of thermal expansion to prevent cracking both when the object cools and when it is heated again. Special alloys are often used for this purpose, ensuring that the coefficients of expansion match, and sometimes thin, metallic coatings may be applied to a metal to create a good bond with the glass.
Es steht eine ganze Reihe von Auftragsschweiß-Technologien zur Verfügung, die dem verschlissenen Teil ein neues und oftmals längeres Leben schenken. Eine Vielzahl von Schweißgutlegierungen verleiht dem reparierten Bauteil eine erhöhte Beständigkeit gegen verschiedene Verschleißarten auch in Kombination mit Schlagbeanspruchung oder Korrosion. Oft ist die Standzeit des reparierten Teiles höher als die des Neuteiles. Deshalb wird bereits bei der Herstellung neuer Bauteile häufig eine Verschleißschutzschicht mittels Schweißen aufgetragen. Je nach Verschleiß- und Beanspruchungsart steht eine große Auswahl geeigneter Schweißzusätze mit unterschiedlich hoher Beständigkeit gegen bestimmte Verschleißarten, Korrosion, Hitze usw. zur Verfügung, die auf das beanspruchte Bauteilareal aufgetragen werden. Dies kann sowohl lokal begrenzt (z.B. Ventilsitz einer Armatur), als auch großflächig (z.B. Oberläche einer Stranggußrolle) geschehen. Neben traditionellen Einsatzgebieten, wie Bergbau und Tiefbau, findet das Auftragsschweißen heute auch in vielen anderen Industriezweigen Anwendung.

Noch leistungsstärker als der Sprühlichtbogen ist der rotierende Lichtbogen. Diese Lichtbogenart ist durch die große Wärmeeinbringung nur für besonders dicke Materialien geeignet. Diese Lichtbogenart zeichnet sich durch ein relativ langes freies Drahtende aus (Stickout). Durch den hohen „Lichtbogendruck" auf das durch den langen Stickout angeschmolzene Drahtende, wird der sich ablösende Tropfen seitlich abgelenkt und geht in einer rotierenden Bewegung in das Schweißbad über.Because glass is very brittle in its solid state, it is often prone to cracking upon heating and cooling, especially if the heating and cooling are uneven. This is because the brittleness of glass does not allow for uneven thermal expansion. Glass that has been welded will usually need to be cooled very slowly and evenly through the glass transition, in a process called annealing, to relieve any internal stresses created by a temperature gradient.
The weld is protected against oxidation. No slag is produced. The working speed is very high. The result is lower heat effects of the surrounding material.

Virtual welding offers novices and trainees the opportunity to get to grips with welding without any risks. CAN BE USED ANYWHERE No matter whether it is at trade shows, in schools or in training workshops: the welding simulators can be used with a high degree of flexibility and without any safety concerns The heat-affected zone (HAZ) is a ring surrounding the weld in which the temperature of the welding process, combined with the stresses of uneven heating and cooling, alter the heat-treatment properties of the alloy. The effects of welding on the material surrounding the weld can be detrimental—depending on the materials used and the heat input of the welding process used, the HAZ can be of varying size and strength. The thermal diffusivity of the base material plays a large role—if the diffusivity is high, the material cooling rate is high and the HAZ is relatively small. Conversely, a low diffusivity leads to slower cooling and a larger HAZ. The amount of heat injected by the welding process plays an important role as well, as processes like oxyacetylene welding have an unconcentrated heat input and increase the size of the HAZ. Processes like laser beam welding give a highly concentrated, limited amount of heat, resulting in a small HAZ. Arc welding falls between these two extremes, with the individual processes varying somewhat in heat input. To calculate the heat input for arc welding procedures, the following formula can be used:

Crystalline solids cohesion is obtained by a metallic or chemical bond which is formed between the constituent atoms. Chemical bonds can be grouped into two types consisting of ionic and covalent. To form an ionic bond, either a valence or bonding electron separates from one atom and becomes attached to another atom to form oppositely charged ions. The bonding in the static position is when the ions occupy an equilibrium position where the resulting force between them is zero. When the ions are exerted in tension force, the inter-ionic spacing increases creating an electrostatic attractive force, while a repulsing force under compressive force between the atomic nuclei is dominant.

There are many types of glass, and it is most common to weld using the same types. Different glasses often have different rates of thermal expansion, which can cause them to crack upon cooling when they contract differently. For instance, quartz has very low thermal expansion, while soda-lime glass has very high thermal expansion. When welding different glasses to each other, it is usually important to closely match their coefficients of thermal expansion, to ensure that cracking does not occur. Also, some glasses will simply not mix with others, so welding between certain types may not be possible. COMBINED ARC This arc consists of a dip transfer arc and a pulsed arc. The necessary penetration and the heat input are generated in the phase of the pulsed arc, while the phase of the dip transfer arc provides for the cooling of the weld pool and makes it easier to manage.Unlike tungsten inert gas welding (TIG) the filler wire melts. At the same time, shielding gas (3) is added through a nozzle, which protects the weld pool (4) against the effect of oxygen and therefore ensures oxidation-free joining of the metal parts (6). The finished weld is also called a weld run or bead (5).
Durch das Metall-Schutzgas-Schweißen lassen sich fast alle schweißgeeigneten Werkstoffe verbinden. Unlegierte und legierte Stähle werden bevorzugt mit Aktivgas, z. B. Kohlendioxid, verschweißt. Dieses Unterverfahren nennt man Metall-Aktivgas-Schweißen, kurz auch MAG-Schweißen genannt Three of the most commonly used crystal lattice structures in metals are the body-centred cubic, face-centred cubic and close-packed hexagonal. Ferritic steel has a body-centred cubic structure and austenitic steel, non-ferrous metals like aluminum, copper and nickel have the face-centred cubic structure. To supply the electrical power necessary for arc welding processes, a variety of different power supplies can be used. The most common welding power supplies are constant current power supplies and constant voltage power supplies. In arc welding, the length of the arc is directly related to the voltage, and the amount of heat input is related to the current. Constant current power supplies are most often used for manual welding processes such as gas tungsten arc welding and shielded metal arc welding, because they maintain a relatively constant current even as the voltage varies. This is important because in manual welding, it can be difficult to hold the electrode perfectly steady, and as a result, the arc length and thus voltage tend to fluctuate. Constant voltage power supplies hold the voltage constant and vary the current, and as a result, are most often used for automated welding processes such as gas metal arc welding, flux cored arc welding, and submerged arc welding. In these processes, arc length is kept constant, since any fluctuation in the distance between the wire and the base material is quickly rectified by a large change in current. For example, if the wire and the base material get too close, the current will rapidly increase, which in turn causes the heat to increase and the tip of the wire to melt, returning it to its original separation distance.
Which Gases are Used in MIG/MAG Welding? MAG welding uses active gases such as pure CO2 or mixed gases (argon, CO2, O2) in various compositions. These are highly reactive. The MAG process is used for unalloyed, low-alloy and high-alloy materials. Subscribe to our newsletter to receive the latest news and events from TWI:

This means that a high deposition rate and deep penetration are possible.Another common process, explosion welding, involves the joining of materials by pushing them together under extremely high pressure. The energy from the impact plasticizes the materials, forming a weld, even though only a limited amount of heat is generated. The process is commonly used for welding dissimilar materials, including bonding aluminum to carbon steel in ship hulls and stainless steel or titanium to carbon steel in petrochemical pressure vessels.

In the case of higher alloy steels and aluminium, helium or argon can be used as the shielding gas, whereby argon is frequently used for cost reasons. The advantage of inert gases is that it is possible to weld with higher temperatures without the material oxidising. MAG welding can only be used indoors in enclosed rooms. Wind and weather could blow the shielding gas away and the welding process would take place without oxidation protection. This weld would then be of reduced quality, susceptible to rust and far less load-bearing.

Many welding processes require the use of a particular joint design; for example, resistance spot welding, laser beam welding, and electron beam welding are most frequently performed on lap joints. Other welding methods, like shielded metal arc welding, are extremely versatile and can weld virtually any type of joint. Some processes can also be used to make multipass welds, in which one weld is allowed to cool, and then another weld is performed on top of it. This allows for the welding of thick sections arranged in a single-V preparation joint, for example. The newest welding product releases from ABICOR BINZEL.

The size and scale of the metal sculptures in this indoor exhibit are mind-blowing; some. Welding thermoplastic is very similar to welding glass. The plastic first must be cleaned and then heated through the glass transition, turning the weld-interface into a thick, viscous liquid. Two heated interfaces can then be pressed together, allowing the molecules to mix through intermolecular diffusion, joining them as one. Then the plastic is cooled through the glass transition, allowing the weld to solidify. A filler rod may often be used for certain types of joints. The main differences between welding glass and plastic are the types of heating methods, the much lower melting temperatures, and the fact that plastics will burn if overheated. Many different methods have been devised for heating plastic to a weldable temperature without burning it. Ovens or electric heating tools can be used to melt the plastic. Ultrasonic, laser, or friction heating are other methods. Resistive metals may be implanted in the plastic, which respond to induction heating. Some plastics will begin to burn at temperatures lower than their glass transition, so welding can be performed by blowing a heated, inert gas onto the plastic, melting it while, at the same time, shielding it from oxygen. The trend of accelerating the speed at which welds are performed in the steel erection industry comes at a risk to the integrity of the connection. Without proper fusion to the base materials provided by sufficient arc time on the weld, a project inspector cannot ensure the effective diameter of the puddle weld therefore he or she cannot guarantee the published load capacities unless they witness the actual installation. This method of puddle welding is common in the United States and Canada for attaching steel sheets to bar joist and structural steel members. Regional agencies are responsible for ensuring the proper installation of puddle welding on steel construction sites. Currently there is no standard or weld procedure which can ensure the published holding capacity of any unwitnessed connection, but this is under review by the American Welding Society.
Gas tungsten arc welding (GTAW), or tungsten inert gas (TIG) welding, is a manual welding process that uses a nonconsumable tungsten electrode, an inert or semi-inert gas mixture, and a separate filler material. Especially useful for welding thin materials, this method is characterized by a stable arc and high quality welds, but it requires significant operator skill and can only be accomplished at relatively low speeds. ." A thermoset is a plastic in which a chemical reaction sets the molecular bonds after first forming the plastic, and then the bonds cannot be broken again without degrading the plastic. Thermosets cannot be melted, therefore, once a thermoset has set it is impossible to weld it. Examples of thermosets include epoxies, silicone, vulcanized rubber, polyester, and polyurethane.

As an industrial process, the cost of welding plays a crucial role in manufacturing decisions. Many different variables affect the total cost, including equipment cost, labor cost, material cost, and energy cost. Depending on the process, equipment cost can vary, from inexpensive for methods like shielded metal arc welding and oxyfuel welding, to extremely expensive for methods like laser beam welding and electron beam welding. Because of their high cost, they are only used in high production operations. Similarly, because automation and robots increase equipment costs, they are only implemented when high production is necessary. Labor cost depends on the deposition rate (the rate of welding), the hourly wage, and the total operation time, including time spent fitting, welding, and handling the part. The cost of materials includes the cost of the base and filler material, and the cost of shielding gases. Finally, energy cost depends on arc time and welding power demand. . Zudem können mittels LMD auch unterschiedliche Materialien wie Stahl und Aluguss verbunden werden, um beispielsweise Batterien für E-Motoren zu fügen
Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding, is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt and join. Along with the wire electrode, a shielding gas feeds through the welding gun. . Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.
Bei den MSG-Prozessen werden in der Praxis verschiedene Lichtbogenarten verwendet. Dabei ergeben sich Unterschiede in den Anwendungsbereichen sowie im Einfluss auf den Grundwerkstoff und den Eigenschaften der späteren Schweißnaht. Der Unterschied zwischen den unterschiedlichen Lichtbogenarten liegt in der Länge des Lichtbogens. Diese hängt im Wesentlichen ab von der Schweißspannung, der Schweißstromstärke, dem verwendeten Schutzgas sowie der Drahtfördergeschwindigkeit. Zu Beachten ist, dass hier alle Parameter in gegenseitiger Abhängigkeit stehen.Other solid-state welding processes include friction welding (including friction stir welding), magnetic pulse welding, co-extrusion welding, cold welding, diffusion bonding, exothermic welding, high frequency welding, hot pressure welding, induction welding, and roll welding.

Ductility is an important factor in ensuring the integrity of structures by enabling them to sustain local stress concentrations without fracture. In addition, structures are required to be of an acceptable strength, which is related to a material's yield strength. In general, as the yield strength of a material increases, there is a corresponding reduction in fracture toughness. . Unlike metals, which have a specific melting point, glasses and plastics have a melting range, called the glass transition. When heating the solid material past the glass-transition temperature (Tg) into this range, it will generally become softer and more pliable. When it crosses through the range, above the glass-melting temperature (Tm), it will become a very thick, sluggish, viscous liquid, slowly decreasing in viscosity as temperature increases. Typically, this viscous liquid will have very little surface tension compared to metals, becoming a sticky, taffy to honey-like consistency, so welding can usually take place by simply pressing two melted surfaces together. The two liquids will generally mix and join at first contact. Upon cooling through the glass transition, the welded piece will solidify as one solid piece of amorphous material.

Der Lichtbogen brennt zwischen einer nicht abschmelzenden Wolframelektrode und dem Werkstück. Die Elektrode, der Lichtbogen und das Schmelzbad werden mit einem inerten Gas vor der Atmosphäre geschützt. Wenn ein Schweißzusatz erforderlich ist, wird er als Kaltdraht zugeführt und vor dem Schmelzbad im Lichtbogen abgeschmolzen. Mit dem WIG-Prozess werden sehr saubere und hochwertige Schweißverbindungen hergestellt. Es entstehen keine Spritzer. Bindefehler, Einbrandkerben und Poren sind leicht zu vermeiden. Der Prozess kann sowohl manuell als auch teil- oder vollmechanisch ausgeführt werden. WIG-Schweißen wird meistens an Aluminium und hochlegierten Stählen eingesetzt, da hier die Nahtqualität gefordert wird, die mit anderen Schweißprozessen kaum erreichbar ist. Der Prozess wird für Schweißverbindungen in Bereichen eingesetzt, die besonders hohe Qualitätsanforderungen haben, z.B. Kernkraft, Chemie, Luft- und Raumfahrt sowie Lebensmittelindustrie.For manual welding methods, labor costs generally make up the vast majority of the total cost. As a result, many cost-saving measures are focused on minimizing operation time. To do this, welding procedures with high deposition rates can be selected, and weld parameters can be fine-tuned to increase welding speed. Mechanization and automation are often implemented to reduce labor costs, but this frequently increases the cost of equipment and creates additional setup time. Material costs tend to increase when special properties are necessary, and energy costs normally do not amount to more than several percent of the total welding cost. In order to protect the arc from the reactive oxygen in the surroundings, a “shielding gas” also flows through the gas nozzle. This suppresses the oxygen during welding and therefore prevents oxidation on the arc and on the weld pool.. MAG welding requires a great deal of experience and is not easy to control. In addition, all rust must be removed from the weld area beforehand. Apart from proper protective clothing, particular attention must also be paid to strict use of eye protection in proper condition, as the weld flame develops a noticeably bright arc.
Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion.Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.. In addition to melting the base metal, a filler material is typically. Resistance welding was also developed during the final decades of the 19th century, with the first patents going to Elihu T in 1885, who produced further advances over the next 15 years. Thermite welding was invented in 1893, and around that time another process, oxyfuel welding, became well established. Acetylene was discovered in 1836 by Edmund Davy, but its use was not practical in welding until about 1900, when a suitable torch was developed. At first, oxyfuel welding was one of the more popular welding methods due to its portability and relatively low cost. As the 20th century progressed, however, it fell out of favor for industrial applications. It was largely replaced with arc welding, as advances in metal coverings (known as flux) were made. Flux covering the electrode primarily shields the base material from impurities, but also stabilizes the arc and can add alloying components to the weld metal.

The process is versatile and can be performed with relatively inexpensive equipment, making it well suited to shop jobs and field work. An operator can become reasonably proficient with a modest amount of training and can achieve mastery with experience. Weld times are rather slow, since the consumable electrodes must be frequently replaced and because slag, the residue from the flux, must be chipped away after welding. Furthermore, the process is generally limited to welding ferrous materials, though special electrodes have made possible the welding of cast iron, nickel, aluminum, copper, and other metals.

Schweißen mit Fülldrahtelektroden enspricht hinsichtlich Handhabung und Ausrüstung dem MIG/MAG-Schweißen. Der Fülldraht ist jedoch nicht massiv, sondern besteht aus einem Blechmantel um einen Pulverkern. Bei der Herstellung wird Bandmaterial zu einem U geformt, mit Pulver gefüllt und dann in einem Rollengang geschlossen PULSED ARC The pulsed arc is made up of a base current phase with a low power and a pulsing current phase with high power without short circuits. This means that almost no spatter is produced. In the pulsing current phase, the welding droplets are detached in a targeted manner via a precisely dosed current pulse. SAF-FRO provides expertise in all the key welding and cutting processes used across all metals-related industries. MIG-MAG Welding The Metal Inert Gas (MIG) or Metal Active Gas (MAG) welding is a semi-automated process, widely used in many sectors of industry Welds can be geometrically prepared in many different ways. The five basic types of weld joints are the butt joint, lap joint, corner joint, edge joint, and T-joint (a variant of this last is the cruciform joint). Other variations exist as well—for example, double-V preparation joints are characterized by the two pieces of material each tapering to a single center point at one-half their height. Single-U and double-U preparation joints are also fairly common—instead of having straight edges like the single-V and double-V preparation joints, they are curved, forming the shape of a U. Lap joints are also commonly more than two pieces thick—depending on the process used and the thickness of the material, many pieces can be welded together in a lap joint geometry. Like the first welding process, forge welding, some modern welding methods do not involve the melting of the materials being joined. One of the most popular, ultrasonic welding, is used to connect thin sheets or wires made of metal or thermoplastic by vibrating them at high frequency and under high pressure. The equipment and methods involved are similar to that of resistance welding, but instead of electric current, vibration provides energy input. Welding metals with this process does not involve melting the materials; instead, the weld is formed by introducing mechanical vibrations horizontally under pressure. When welding plastics, the materials should have similar melting temperatures, and the vibrations are introduced vertically. Ultrasonic welding is commonly used for making electrical connections out of aluminum or copper, and it is also a very common polymer welding process.
Many thermoplastics can also be welded using chemical solvents. When placed in contact with the plastic, the solvent will begin to soften it, bringing the surface into a thick, liquid solution. When two melted surfaces are pressed together, the molecules in the solution mix, joining them as one. Because the solvent can permeate the plastic, the solvent evaporates out through the surface of the plastic, causing the weld to drop out of solution and solidify. A common use for solvent welding is for joining PVC or ABS (acrylonitrile butadiene styrene) pipes during plumbing, or for welding styrene and polystyrene plastics in the construction of models. Solvent welding is especially effective on plastics like PVC which burn at or below their glass transition, but may be ineffective on plastics like Teflon or polyethylene that are resistant to chemical decomposition. The equipment is relatively inexpensive and simple, generally employing the combustion of acetylene in oxygen to produce a welding flame temperature of about 3100 °C (5600 °F). The flame, since it is less concentrated than an electric arc, causes slower weld cooling, which can lead to greater residual stresses and weld distortion, though it eases the welding of high alloy steels. A similar process, generally called oxyfuel cutting, is used to cut metals. Fracture toughness is measured using a notched and pre-cracked rectangular specimen, of which the dimensions are specified in standards, for example ASTM E23. There are other means of estimating or measuring fracture toughness by the following: The Charpy impact test per ASTM A370; The crack-tip opening displacement (CTOD) test per BS 7448–1; The J integral test per ASTM E1820; The Pellini drop-weight test per ASTM E208. Many distinct factors influence the strength of welds and the material around them, including the welding method, the amount and concentration of energy input, the weldability of the base material, filler material, and flux material, the design of the joint, and the interactions between all these factors. To test the quality of a weld, either destructive or nondestructive testing methods are commonly used to verify that welds are free of defects, have acceptable levels of residual stresses and distortion, and have acceptable heat-affected zone (HAZ) properties. Types of welding defects include cracks, distortion, gas inclusions (porosity), non-metallic inclusions, lack of fusion, incomplete penetration, lamellar tearing, and undercutting.
The metalworking industry has instituted specifications and codes to guide welders, weld inspectors, engineers, managers, and property owners in proper welding technique, design of welds, how to judge the quality of Welding Procedure Specification, how to judge the skill of the person performing the weld, and how to ensure the quality of a welding job. Methods such as visual inspection, radiography, ultrasonic testing, phased-array ultrasonics, dye penetrant inspection, magnetic particle inspection, or industrial computed tomography can help with detection and analysis of certain defects. A motor automatically unwinds a filler wire (2) from a reel and feeds it automatically towards the welding point. This wire is guided directly to the welding point by the contact sleeve (1).

World War I caused a major surge in the use of welding, with the various military powers attempting to determine which of the several new welding processes would be best. The British primarily used arc welding, even constructing a ship, the "Fullagar" with an entirely welded hull. Arc welding was first applied to aircraft during the war as well, as some German airplane fuselages were constructed using the process. Also noteworthy is the first welded road bridge in the world, the Maurzyce Bridge designed by Stefan Bryła of the Lwów University of Technology in 1927, and built across the river Słudwia near Łowicz, Poland in 1928.

Resistance welding involves the generation of heat by passing current through the resistance caused by the contact between two or more metal surfaces. Small pools of molten metal are formed at the weld area as high current (1000–100,000 A) is passed through the metal. In general, resistance welding methods are efficient and cause little pollution, but their applications are somewhat limited and the equipment cost can be high. MIG/MAG-Schweißen ist wesentlich produktiver als Lichtbogenhandschweißen. Der häufige Elektrodenwechsel entfällt und die Netto-Ausbringung ist wesentlich größer, da kein Rest mehr übrigbleibt.

Covalent bonding takes place when one of the constituent atoms loses one or more electrons, with the other atom gaining the electrons, resulting in an electron cloud that is shared by the molecule as a whole. In both ionic and covalent bonding the location of the ions and electrons are constrained relative to each other, thereby resulting in the bond being characteristically brittle.

During the 1920s, major advances were made in welding technology, including the introduction of automatic welding in 1920, in which electrode wire was fed continuously. Shielding gas became a subject receiving much attention, as scientists attempted to protect welds from the effects of oxygen and nitrogen in the atmosphere. Porosity and brittleness were the primary problems, and the solutions that developed included the use of hydrogen, argon, and helium as welding atmospheres. During the following decade, further advances allowed for the welding of reactive metals like aluminum and magnesium. This in conjunction with developments in automatic welding, alternating current, and fluxes fed a major expansion of arc welding during the 1930s and then during World War II. In 1930, the first all-welded merchant vessel, M/S Carolinian, was launched. Mag Schweißen Gas / Bezugsquellen oder einfacher gesagt wo bekomme ich mein Gas her.

The composition of the shielding gas has a substantial effect on the stability of the arc, metal transfer and the amount of spatter. The shielding gas also affects the behaviour of the weld pool, particularly its penetration and the mechanical properties of the welded joint.The most common gas welding process is oxyfuel welding, also known as oxyacetylene welding. It is one of the oldest and most versatile welding processes, but in recent years it has become less popular in industrial applications. It is still widely used for welding pipes and tubes, as well as repair work. Weld Informed: The Perfect Welding Newsletter
Like spot welding, seam welding relies on two electrodes to apply pressure and current to join metal sheets. However, instead of pointed electrodes, wheel-shaped electrodes roll along and often feed the workpiece, making it possible to make long continuous welds. In the past, this process was used in the manufacture of beverage cans, but now its uses are more limited. Other resistance welding methods include butt welding, flash welding, projection welding, and upset welding.

Pressure may also be used in conjunction with heat or by itself to produce a weld. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or oxidized.
