Tandem-arc Welding
From GAWDAwiki
Tandem-arc welding is a variant of twin-arc welding that has the unique feature of two independent welding wires/electrodes, both of which can be of different type and size from each other. Because of a difference in parameters and requirements for a tandem application, two separate power sources would be required.[1]
The Tandem Process
The tandem process is a GMAW automated process that increases the application range of traditional single-wire GMAW processes: Two electrically isolated wires/electrode are positioned in line, in the direction of travel. The lead electrode controls the majority of the base plate penetration. The trail electrode controls weld bead appearance and contour, edge wetting, and adding to the overall deposit rate. The process uses a true tandem configuration of dual power sources and two wire feeders to generate two separate welding arcs. The output of the two power sources are coordinated by either a robot controller for robotic applications, or by a tandem interface for dedicated hard automated work cells.[2]
