Tandem MIG
High-Speed and High-Deposition Welding
What Is It?
Tandem MIG is a dual wire GMAW process that is used in automated welding applications to improve welding productivity and part throughput. The process utilizes two welding power sources and two wire feeders acting in tandem to deliver two wire electrodes through a single welding torch. The dual wire welding torch, capable of often doubling the welding output of a single wire torch, is used in hard automation and robotic arc welding cells in the same manner as a single wire welding torch would be. The two welding arcs that are generated in the Tandem MIG process are electrically isolated from one another and are

controlled independently. The welding arcs work together, generally separated by less than 0.50 inches, in the same weld pool. The independent control of the two welding arcs is used to control the thermal and fluid dynamics of the weld pool to further enhance welding performance. The added deposit rate achieved by the dual wire delivery and the added weld pool control is used to overcome single wire limitations to produce high travel speeds and electrode
