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.
