welding joint
21Thermite welding — is the process of igniting a mix of high energy materials, (which is also called thermite), that produce a molten metal that is poured between the working pieces of metal to form a welded joint. It was developed by Hans Goldschmidt around 1895.… …
22Arc welding — uses a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. They can use either direct (DC) or alternating (AC) current, and consumable or non consumable electrodes.… …
23Oxy-fuel welding and cutting — Oxyacetylene redirects here. For the song, see Cubanate. Side of metal, cut by oxygen propane cutting torch …
24Laser beam welding — (LBW) is a welding technique used to join multiple pieces of metal through the use of a laser. The beam provides a concentrated heat source, allowing for narrow, deep welds and high welding rates. The process is frequently used in high volume… …
25Electrogas welding — (EGW) is a continuous vertical position arc welding process developed in 1961, in which an arc is struck between a consumable electrode and the workpiece. A shielding gas is sometimes used, but pressure is not applied. A major difference between… …
26Electroslag welding — (ESW) is a highly productive, single pass welding process for thick (greater than 25mm up to about 300mm) materials in a vertical or close to vertical position. (ESW) is similar to electrogas welding, but the main difference is the arc starts in… …
27scarf joint — noun a joint made by notching the ends of two pieces of timber or metal so that they will lock together end to end • Syn: ↑scarf • Derivationally related forms: ↑scarf (for: ↑scarf) • Hypernyms: ↑joint * * * …
28Forge welding — is a welding process of heating two or more pieces of metal and then hammering them together. The process is one of the simplest methods of joining metals and has been used since ancient times. Forge welding is versatile, being able to join a… …
29Flash welding — is a form of resistance welding that involves pressing two ends together, while simultaneously running a current between them. This has the effect of forming a joint between the two metals that is free of oxides as the surfaces of the two joining …
30butt welding — noun creating a butt joint by welding • Syn: ↑butt welding • Derivationally related forms: ↑buttweld (for: ↑butt welding), ↑butt weld (for: ↑butt welding), ↑ …
