WELDING DEVICE AND METHOD FOR STAINLESS STEEL WITH HIGH CURRENT TIG WELDING

摘要

PURPOSE: A welding machine of stainless steel using high-current TIG welding and a method thereof are provided to enable the formation of a sound back bead, since a key hole is welded by a fist TIG torch and is finished by a second TIG torch. CONSTITUTION: A welding machine of stainless steel using high-current TIG welding comprises a jig table(100), a first TIG torch(110), and a second TIG torch(120). The first TIG torch passes by a welded junction of stainless steel on the jig table. The first TIG torch enables key hole type TIG welding. The second TIG torch enables thermal conductive welding for finishing welding.
