Abstract

PURPOSE: To subject aluminum to polarity inversion pulse TIG welding and improve quality by forming the minus current of an electrode into high-frequency pulses and the plus current to single pulse of a high peak.
CONSTITUTION: The minus current iSP of an electrode is formed into high-frequency pulses, whereby the deep penetration welding of aluminum plates is achieved and the high-speed welding of aluminum sheets is achieved. The plus current iRP of the electrode of this time is formed into single pulse of a high peak having the current value 1W4 times the high-frequency pulse current, and is inverted at a fixed frequency, whereby cleaning is caused.
