Title:
ARC WELDING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2016/125540
Kind Code:
A1
Abstract:
An arc welding control method that performs welding by carrying out forward-reverse feed control that alternately switches a feed rate Fw between forward feed periods and reverse feed periods and generating short periods and arc periods, wherein when a metal transfer mode is a globular transfer mode, the synchronized short ratio during the forward-reverse feed control is calculated, and the feed rate Fw frequency Sf is automatically adjusted within a range of 70 - 120 Hz such that this synchronized short ratio is a maximum value. The synchronized short ratio is the ratio of the number of shorts generated during forward feed periods with respect to the number of forward feed periods during a unit time.
