Study on MIG-TIG hybrid brazing of galvanised thin sheet

Abstract To increase productivity when joining galvanised sheet metal, metal inert gas (MIG) and tungsten (TIG) arc brazing are combined in a hybrid process. This coupling of two processes increases speed reduces weld reinforcement the tendency to spatter. Because arcs 6 mm apart, they influence each other. Therefore, blowing action is major challenge brazing. A current modulation optimal relative position other compulsory conditions. Selected parameters tested order verify Overlap joints brazed on sheets. The mechanical-technological properties determined. It has been shown that can achieve significantly higher with same or better quality compared standard For realisation process, software-controlled welding machines used, which will replace conventional power sources future.
