IPC: B23K9/095
Filed: 2011-03-24
Abstract: PROBLEM TO BE SOLVED: To suppress a deterioration in the bead appearance caused by magnetic blow in DC pulse arc welding.SOLUTION: In the arc welding control method for performing the DC pulse arc welding by passing a welding current formed of a peak current during a peak period and a base current during a base period, test welding is performed by the DC pulse arc welding in which weld parts Ps2-Pe2 with the occurrence of the magnetic blow are discriminated out of a plurality of weld parts according to a rise in welding voltage during the base period, and stored. In the actual application, welding is performed by the DC pulse arc welding when weld parts Ps1-Pe1, Ps3-Pe3 other than the stored weld parts with the occurrence of the magnetic blow are welded. When the stored weld parts Ps2-Pe2 with the occurrence of the magnetic blow are welded, the welding is performed by automatically changing the welding method from the DC pulse arc welding to AC pulse arc welding. Since arc interruption caused by the magnetic blow hardly occurs in the AC pulse arc welding, the bead appearance can be kept favorably.
