Cold Weld - Welding with minimum heat input
By using a negative phase, targeted heat-placing control is possible during the Cold Weld process which allows a very low heat input. This "cold" arc welding allows optimum control of the welding process. The thermal loading of base material is reduced and the origin material characteristics remain nearly unchanged. Thus a high weld seam quality at a good gap briding ability and increased weld speed can be achieved. The Cold Weld process is mainly used for thin to medium plate thicknesses.
