Abstract
A welding apparatus for welding workpieces of high-temperature superalloys is provided. The welding apparatus includes a heat source for producing a heat input zone on the workpiece surface, a supplying device for supplying welding filler into the heat input zone and a transporting device for producing a relative movement between the heat source and the supplying device on the one hand and the workpiece surface on the other hand. The welding apparatus further includes a control unit with a control program, which carries out the relative movement in such a way that the welding power and the diameter of the heat input zone are set such that the cooling rate during the solidifying of the material is at least 8000 Kelvins per second.
