Overview

Plasma-MIG hybrid welding technology is a new technique that combines the two common welding processes, plasma and MIG, into a composite heat source welding process. This innovative welding technology can replace or improve the majority of conventional welding processes such as MIG, MAG, TIG, submerged arc welding, and plasma welding. It is suitable for continuous butt welding, lap welding, seam welding, and penetration welding (spot welding) combinations, and is versatile for welding various metal materials. The plasma-MIG hybrid system can perform metal thin plate brazing for automotive body manufacturing, while the plasma-MIG hybrid arc welding system can achieve high-quality, high-efficiency welding of high-strength steel without preheating.

Plasma + MIG welding systems are suitable for automated (robotic) welding, including: integrated torch, control console (with plasma power supply, cooling system, and gas control system), MIG/MAG power source, and wire feeding unit.

Comparing Laser Arc Hybrid Welding Technology

Plasma + MIG hybrid welding technology is similar to laser arc hybrid welding technology. This process has a higher tolerance for joint gaps than laser arc hybrid welding. It is typically used for welding various metal sheets with thicknesses of 4-10mm in a single pass. Its heat input is about 50% of conventional MTG welding, resulting in less thermal deformation of the welded parts compared to conventional MIG welding. The welding efficiency is 2-4 times that of standard MIG welding. The investment in a plasma + MIG hybrid welding system is less than that of a laser arc hybrid system with equivalent welding capacity.
