METHOD FOR ARC WELDING USING INDIVIDUAL PULSE CONTROL FOR MATERIAL DETACHMENT AND ACCELERATION

摘要

A method of arc welding wherein the welding current delivered to the welding electrode is periodically caused to assume a plurality of essentially different amplitude values such that a waveform having at least a main and auxiliary amplitude is provided to the electrode. The main amplitude is provided to fuse and detach material from the end of the electrode while the auxiliary amplitude is used to accelerate the detached material to the weld puddle.
