Two in-line wires are fed simultaneously and melted into two arcs. Due to the consequent separation of the two electrical circuits, the arc can be controlled in detail. Enormous efficiency, low heat input, excellent weld seam quality and a very high deposition rate are the great advantages of the TANDEM WELD Process.
