ARC-WELDING CONTROL METHOD

ARC-WELDING CONTROL METHOD

A pulse welding period Tp includes a first peak period Tp1 for supplying a first peak current Ip1 to a welding wire 18, a first base period Tb1 for supplying a base current Ib smaller than the first peak current Ip1 to the welding wire 18, a second peak period Tp2 for supplying a second peak current...

Zusammenfassung:A pulse welding period Tp includes a first peak period Tp1 for supplying a first peak current Ip1 to a welding wire 18, a first base period Tb1 for supplying a base current Ib smaller than the first peak current Ip1 to the welding wire 18, a second peak period Tp2 for supplying a second peak current Ip2 to the welding wire 18 after alternately repeating the first peak period Tp1 and the first base period Tb1 (n - 1) times (n is an integer equal to or larger than 2), and a second base period Tb2 for supplying the base current Ib to the welding wire 18. The second peak current Ip2 is larger than the first peak current Ip1, and droplets are transferred from the welding wire 18 during the second peak period Tp2 or the second base period Tb2.
