Inert gas arc welding method for carrying out welding process, involves carrying out short circuit of polarity change, by which welding rod is made as negative pole

摘要

The Inert gas arc welding method involves carrying out a short circuit of a polarity change, by which the welding rod is made as a negative pole, and after the change of polarity an arc is ignited with negative pole of the welding rod. Another polarity change is carried out in the process cycle, in which the welding rod is made as positive pole after the progress of an arc phase.
