corner joint - 1" to 1/2" @ 18 ipm

Single-Pass CJP Square-Groove/Corner Joint with Steel Backing

This single-pass weld was made using our hybrid plasma-GMAW process (SuperMIG®), in a square-groove/corner joint configuration (zero beveling), in the 1G position, with a root opening of 3 mm and at a travel speed of 18 in/min (457 mm/min). This scenario utilized 90/10 (Argon/CO2) shielding gas and 1/16” E70C-6M H4 metal-cored wire in a spray transfer (CV) using steel backing. 

Where is this applicable?

Corner joints are typically used in trucks and cranes outriggers although the design can also be used in other structures. Normally using a single bevel with the performance of 2 or 3 passes with conventional processes, SuperMIG® allows for the performance of a single pass, with no bevel, up to a thickness of 12 mm (1/2") in the thinner plate.
