Title:
アーク溶接制御方法
Document Type and Number:
Japanese Patent JP7113329
Kind Code:
B2
Abstract:
To improve an appearance of a welded portion by stabilizing arc generation at the starting time thereof.SOLUTION: Arc welding is performed by setting the sum of a welding current ON period Ton and a welding current OFF period Toff as a welding period Tc. An arc welding control method comprises: a first short circuit step for shorting a welding wire 18 with a base material 17 just before completion of the welding-current ON period Ton; and a wire tip end position control step for changing the tip end shape of the welding wire 18 by supplying first electric current Ic1 to the welding wire 18 at a first time T1 after the first short circuit step, so as to adjust the distance between the tip end of the welding wire 18 and the base material 17 to be a first distance WD1. The welding current OFF period Toff is started after completion of the wire tip end position control step.SELECTED DRAWING: Figure 4
