SuperMIG® - Hybrid Welding Technology Combining Plasma and GMAW in One Torch
These welds were made using our hybrid plasma-GMAW process (SuperMIG®) in a lap joint/fillet weld configuration, in the 2F position, and at a travel speed of 65 in/min (1,651 mm/min). This scenario was performed with a 1.2mm gap between the sheets, with 90/10 (Argon/CO2) shielding gas and 0.045” ER70S-3 solid wire in a CV spray transfer.
For this application, SuperMIG® was able to achieve quality welds on automotive grade galvanized steel at speeds approximately twice as fast as current processes. The welds submitted for RT evaluation satisfied the requirements of current General Motors and Ford Motor Company weld quality specifications.
In the automotive industry, particularly in welding of chassis frames, cross members and suspension parts, especially where higher welding speeds (>35 ipm) are desired. SuperMIG® is capable of speeds of 60 to 80 ipm in galvanized steel grades 5060G and 90G.
