Welding — is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld puddle ) that cools to… … Wikipedia
welding — Technique for joining metallic parts, usually through the application of heat. Discovered in the 1st millennium AD during attempts to manipulate iron into useful shapes, the technique produced a strong, tough blade. Welding traditionally involved … Universalium
Resistance welding — refers to a group of welding processes that produce coalescence of faying surfaces where heat to form the weld is generated by the resistance of the welding current through the workpieces. Some factors influencing heat or welding temperatures are … Wikipedia
Electric 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… … Wikipedia
Seam welding — Resistance Seam Welding is a resistance welding process that produces a weld at the faying surfaces of overlapped parts along a length of a joint. The weld may be made by overlapping weld nuggets, a continuous weld nugget or by forging the joint… … Wikipedia
