Electrical contact resistance effect on resistance spot welding
2012年5月1日 · The effects of local electrical contact resistance on transport variables, cooling rate, solute distribution, and nugget shape after solidification responsible for microstructure of the fusion zone during resistance spot welding are realistically and systematically investigated.
Electric Resistance Welding - Your Electrical Guide
Electric resistance welding is a group of welding processes in which welding heat is obtained from resistance of the work to the flow of electrical current and by application of pressure. No flux or filler metal is added.
Electric resistance welding - Wikipedia
Electric resistance welding (ERW) is a welding process in which metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint. [1] Electric resistance welding is widely used, for example, in manufacture of steel pipe and in assembly of bodies for automobiles. [ 2 ]
