welding characteristics
1Welding power supply — A welding power supply is a device that provides an electric current to perform welding. Welding usually requires high current (over 80 amperes) and it can need above 12,000 amps in spot welding. Low current can also be used; welding two razor… …
2Friction stir welding — (FSW) is a solid state joining process (meaning the metal is not melted during the process) and is used for applications where the original metal characteristics must remain unchanged as far as possible. This process is primarily used on aluminum …
3Shot welding — is a specific type of spot welding used to join two pieces of metal together. This is accomplished by clamping the two pieces together and then passing a large electric current through them for a short period of time. Assuming the right amount of …
4Shielded metal arc welding — (SMAW), also known as manual metal arc (MMA) welding, flux shielded arc welding …
5Oxy-fuel welding and cutting — Oxyacetylene redirects here. For the song, see Cubanate. Side of metal, cut by oxygen propane cutting torch …
6Electric resistance welding — (ERW) refers to a group of welding processes such as spot and seam welding that produce coalescence of faying surfaces where heat to form the weld is generated by the electical reistance of material vs the time and the force used to hold the… …
7Pattern welding — is the practice in sword and knife making of forming a blade of several metal pieces of differing composition that are forge welded together and twisted and manipulated to form a pattern. Often incorrectly called Damascus steel (which is produced …
8Magnetic pulse welding — (MPW) is a welding process that uses magnetic forces to drive two workpieces together and weld them together. The welding mechanism is most similar to that in explosion welding.[1] Process A very high AC current (the primary current ) is passed… …
