Abstract

PURPOSE: To make sufficient the penetration of welding portion on purpose to prevent the generation of defect such as slag-inclusion, etc., by pushing back and expanding the metal in molten pool respectively depending on the gas spouting from the primary and secondary gas nozzles placed in front and rear of the welding-forward direction of the contact tube.
