Servos Improve Resistance Welding Quality and Speed Although invented over 100 years ago, the resistance welding process, commonly called spot welding, has never been considered an exact science. With three main variables at work - welding current (amps), weld time (duration of current flow), and welding pressure (forging force) - consistent spot welding quality has been hard to guarantee. However, with the advent of modern electronic controls ...
