Title: Output control method of pulse arc welding
Inventor: YAMADA HIROTAKA
IPC: B23K9/095
Filed: 2019-02-27
Abstract: To keep a welding state stable, even when a distance between a power feeding chip and a base metal is long, in pulse arc welding.SOLUTION: In an output control method of pulse arc welding for sending a welding wire, and welding by controlling an inclination Ks of an external characteristic of a welding power supply, a distance Lr between a power feeding chip and a base metal is detected, and an absolute value of the inclination Ks of the external characteristic is changed so as to become smaller as the distance Lr between the power feeding chip and the base metal become longer. When the distance Lr between the power feeding chip and the base metal is short, the inclination Ks is enlarged, to thereby stabilize a welding state. When the distance Lr between the power feeding chip and the base metal is long, the inclination Ks is reduced, to thereby stabilize the welding state.SELECTED DRAWING: Figure 1
