Hybrid Process for High-Speed Welding
The interface and torch, patented by Plasma Laser Technologies, integrates with any of the commonly used GMAW welding equipment.
Super-MIG combines the deep penetration characteristics of plasma-arc welding with the high wire-deposition rates of GMAW. These two processes are combined in a unique torch. Either an arc-welding robot or hard automation is required to control the movement of the torch, and an automated torch-cleaning device is required to periodically clean the torch.
During tests on zinc-coated sheet, the results of the process included:
• Successful and consistent welding without holes or discontinuities;
• High welding speed with a narrow heat-affected zone, assuring a minimum level of post-weld deformations;
• Significant reduction in joint preparation and tooling requirements compared to laser welding, due to the ability of the Super-MIG process to tolerate much larger variable gaps than a laser process; and
• Clean welds without spatter, meeting automotive requirements.
