ARC WELDING METHOD AND ARC WELDING DEVICE

摘要

Disclosed is an arc welding method wherein when a weld-ending signal is input while arcing, the welding wire is accelerated, causing a short between the welding wire and a parent material; thereafter the welding wire is retracted, and when a predetermined wire retraction speed is attained, the wire supply speed is fixed at the predetermined wire retraction speed; after retracting for a predetermined period of time, the supply of welding wire is stopped; and considering the time the short began during retraction of the welding wire as the starting point in time, a fixed, predetermined welding current is output for a predetermined length of welding time, and then welding output is stopped.
