Consumable electrode type arc welding method and device therefor

TLDR
In this article, a welding method capable of increasing or decreasing a welding wire feeding speed during welding is presented, where, after short-circuiting is detected, the welding wire feed speed is decreased, and, after a transfer to arcing by being freed from short circuiting, the wire feed rate is increased.

Arc welding control method

TL;DR: In this paper, a method for controlling pulse arc welding where an arc is created between a wire and a base material, a pulse waveform different from the pulse waveforms for steady-state welding is outputted when a predetermined time has passed since short-circuit welding control was started at arc start, and after a sufficiently large melt pool is formed, the Pulse waveform for the steady state welding was outputted This reduces the generation of spatters after an arc was created and until the arc is stabilized
