PULSED ARC WELDING METHOD

摘要

An objective of the present invention is to provide a high current pulsed arc welding method which reduces spatter and suppresses wearing of a tip. The method of the present invention comprises: using shielding gas to perform pulsed arc welding; a pulse current of the pulsed arc welding having a pulse peak current of 550-950 A; a pulse base current of 550 A or lower; a difference between the pulse peak current and the pulse base current of 200-600 A; and a pulse frequency of 50-200 Hz.
