Document Type and Number:
WIPO Patent Application WO/2022/209432
Kind Code:
A1
Abstract:
The present invention suppresses the phenomenon of a disturbance in the regularity of droplet transfer, and reduces sputter. This welding control method, which controls a pulse waveform having one cycle formed of a first pulse period (T1) and a second pulse period (T2) , has: a voltage detection step for outputting, by a voltage detection means (VD), a voltage detection signal (Vo); a voltage deviation average calculation step for calculating, by a voltage deviation average calculation means (81), a voltage deviation average value (Verrp2_ave) in a predetermined section in the second pulse period (T2), on the basis of a difference signal, which is a difference between the voltage detection signal (Vo) and a predetermined set voltage (Vs); and a control amount calculation step for calculating, by a control amount calculation means (82), a control amount for at least one of a first peak current value (Ip1) and a second peak current value (Ip2), on the basis of the voltage deviation average value (Verrp2_ave).
