Method of resistance welding thin sheet and arrangement for carrying out the method

摘要

The invention relates to a method of resistance welding, in particular for fabricating thin-walled sheet-metal boxes on roller seam welders, and an arrangement for carrying out the method. The method is characterised in that the current density in the weld-deposit volume elements through which the welding current passes is modulated with a frequency f2 by means of a further magnetic field acting on the magnetic field of the welding current. <IMAGE>
