electric resistance welding

 noun


Definitions

  1. Any joining process that relies on passing an electrical current through a workpiece. The heat is generated by the metal’s resistance to the electrical current. In the tube and pipe industry, high-frequency, noncontact electrical resistance welding is so common that the abbreviations HF and ERW are used interchangeably. However, high-frequency isn’t the only useful ERW process. Many frequencies are used, including direct current, which has no frequency at all, as is contact welding.
