Abstract
The force (F) is derived from one or several electromagnetic forces each one of which is developed by the effect of a current (I.sub.s, I.sub.B) that circulates through a conductor (8) buried within a magnetic field.
Claims9
A head for a spot-welding machine or for a crimping machine, said head comprising an electrode (3) for supplying a welding or crimping current (I.sub.s) to a part (6a) which is welded onto another part (6b), or which is crimped, said electrode exerting a force (F) on said part (6a) during a welding or crimping operation, an electromagnet (10), and means for developing said force (F) responsive to at least one magnetic force, said magnetic forces being developed by the effect of a current (I.sub.s, I.sub.B) that circulates through a conductor flux lines of a magnetic field which is generated by said electromagnet (10).
