Abstract

The disclosed method is for MIG welding of high-alloyed steels by means of a pulsed arc by cyclically controlling the arc to produce a starting phase 1, a welding phase 2, and a cooling phase 3; wherein the feed speed Vd of the electrode wire in the direction of the weld pool is controlled synchronously with the starting phase and with the cooling phase respectively to increase to an upper value and to decrease to a lower value. Also disclosed is an apparatus for practicing the above method, which comprises a circuit, driven by a frequency generator, which controls the time sequence of the starting phase, the welding phase, and the cooling phase in each cycle and operates a basic current circuit, a pulsing current circuit, and an electrode wire feed mechanism synchronously to one another. Specific time sequence and frequencies are disclosed. <IMAGE>
