SuperMIG® - Hybrid Welding Technology Combining Plasma and GMAW in One Torch
This single-pass CJP weld was made using a hybrid plasma-GMAW process in a square-groove/butt joint configuration (zero beveling) in the 1G position, with a root opening of 0.052”, and at a travel speed of 25 in/min (635 mm/min). This scenario utilized 95/5 (Argon/CO2) shielding gas and 0.052” ER70S-6 wire in a spray transfer (CV) using copper bar backing. Thinner materials can be welded at even higher speeds.
This is a typical joint that can be utilized in the manufacturing of cranes (when using the C channel design), excavators and loaders arms, various deck applications in shipbuilding and rail, as well as pressure vessels, especially those welds performed in a "seam welder", where the process can be easily retrofitted in.
