摘要： In a TIG welding process with controlled welding current pulses, DC current pulses with the frequency set at from tens to hundreds Hz (most preferably from 30 to 300 Hz) are fed to an electrode and current pulses are also fed to a filler wire so that an arc is caused to swing, whereby a large pool of molten metal can be maintained in a positive and stable manner due to the high arc pressure obtained when the welding current pulses at from tens to hundreds Hz is used.
