Abstract

A process for welding >=2 parts together where, by remote control using a fluid, pref. by pneumatic operation, >=2 conductors are connected to the two parts for electric resistance welding then, using the same remote control device, >=1 of the conductors is removed, thus interrupting the heating. The removal of the conductor is commenced before the heating is interrupted. One conductor is pref. stationary and the other mobile, the pref. device using a compressed air cylinder actuated by a solenoid valve to operate a spring-loaded mobile conductor and an electric circuit contg. two switches in series. Using this device the resistance welding cycle time can be reduced by up to 30% of conventional devices.
