Title: Gma welding method
Inventor: SETA ICHIROU
IPC: B23K9/173
Filed: 1983-07-29
Abstract: PURPOSE:To eliminate the mutual interference of arcs and to stabilize welding by conducting the pulse current of the same frequency to plural electrodes disposed in the welding direction and controlling the period when the current conduction between the adjacent electrodes is overlapped to a prescribed range of the pulse width or below. CONSTITUTION:For example, in a GMA welding disposed two electrodes in welding direction, the pulse current of the same frequency which is 1/2 the duty ratio is conducted alternately to a preceding electrode and a succeeding electrode and the period (d) when the conduction of the pulses between both electrodes is overlapped is controlled to <=50% the pulse current width (a). The pulse frequency is made about >=50Hz, more preferably about >=100Hz. The arc interference between the adjacent electrodes is thus eliminated and stable welding is made possible. The arc pressure is decreased and the highly efficient welding without any welding defect is made possible.
