Resistance Welding Machine

Resistance welding, sometimes called electric resistance welding (ERW),is a process by which metals can be joined together by applying pressure and ...Resistance welding machines are designed and built for a wide range of automotive, aerospace and industrial applications. Through automation, the action of these machines is highly controlled and repeatable allowing manufacturers to staff production readily.The phrase "resistance welding" derives from the metal's electrical resistance properties, generating heat while current flows between two electrodes. The resistance welding process joins two metal pieces by pressing electrodes to their surfaces, creating good contact pointResistance welding is used for joining two metals. It consists of a welding head, which holds the metal between its electrodes and applies pressure, and a welding power supply, which applies electric current to the metal to be welded. Resistance generates friction heat when force is applied.Electric resistance welding (ERW) is a welding process where metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint. Electric resistance welding is widely used, for example, in manufacture of steel pipe and in assembly of bodies for automobiles.
