31Flux-cored arc welding — (FCAW) is a semi automatic or automatic arc welding process. FCAW requires a continuously fed consumable tubular electrode containing a flux and a constant voltage or, less commonly, a constant electric current welding power supply. An externally …
32American Welding Society — The American Welding Society (AWS) is a nonprofit organization dedicated to advancing the science, technology, and application of welding and allied joining and cutting processes, including brazing, soldering, and thermal spraying. The… …
33Laser 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… …
34Electroslag 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… …
35spot welding — noun creating an overlapping joint by welding at small points • Syn: ↑spot welding • Derivationally related forms: ↑spotweld (for: ↑spot welding), ↑spot weld (for: ↑spot w …
36Flash 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 …
37Upset welding — is a special way of welding, in which two pieces of material are forged together at elevated temperatures. There are different ways to reach this temperature, but a current through the interface, friction or sometimes an external source are used …
38spot welding — n. a welding process in which overlapping metal pieces are held under great pressure between two electrodes, between which a brief, powerful current is passed, effecting the weld spot weld vt., vi. spot welder n. * * * …
39electric welding — n. welding using electric current for melting both metal works and welding rod …
40resistance welding — /rəˈzɪstəns wɛldɪŋ/ (say ruh zistuhns welding) noun a form of welding in which the heat required to fuse the metal surfaces to be welded is produced by a current flowing across the contact resistance between them …
