Resistance Welding | Article about Resistance

Resistance welding is done on resistance welding machines. The welding transformer of the machine lowers the line voltage to 1–15 volts. Electrodes made of copper alloys are used to supply a current of 1–200 kiloamperes and to press the pieces together. The power of such machines is 0.5-500 kilovolt-amperes.
