Welding tongs for electrical resistance welding has two electrodes, of which at least one is attached to electrode arm, force sensor arranged on one electrode arm holder

摘要

The arrangement has two electrodes, of which at least one is attached to an electrode arm (3a,3b), an arrangement for moving at least one electrode arm, whereby each electrode arm is held at the end by an electrode arm holder, an arrangement for producing the welding current and a force sensor for detecting the actual value of the force between the two electrodes. The force sensor (63) is arranged on one of the electrode arm holders (64). AN Independent claim is also included for the following: a method of assessing the quality of a welded joint.
