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.
Mazak OPTIPLEX Fiber Laser-Cutting System
Compared to conventional laser processing machines, the OPTIPLEX Fiber significantly increases the productivity of thin worksheet cutting with impressive accuracy and cuts up to 0.875” in CRS. The laser is designed to process reflective materials with greater thicknesses and at greater speeds than its CO2 counterpart.
