The goal of this project was to increase the productivity and throughput of mechanized Gas Metal Arc Welding by providing a low-cost modification to existing equipment, increasing weld penetration, and reducing filler metal usage and weld fume. Ultimately, it became apparent that modern inverter-type welding power sources might be capable of operation in ranges that would significantly enhance productivity. Following this approach, several power supplies were tested and found to be capable of operating at much higher speeds than used for typical GMAW. The project team examined easily implemented parameter sets for inverter-type power supplies that demonstrate excellent penetration at double the speed of typical Gas Metal Arc Welding (GMAW). The equipment and parameters are capable of operating on panel lines, in other mechanized or robotic welding areas, and in pipe shops.
