By using a negative phase, targeted heat-placing control the COLD WELD Process allows for very low heat input. This “cold” arc welding provides 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 with a good gap bridging ability and increased weld speed can be achieved. The COLD WELD Process is mainly used for thin to medium plate thicknesses.
