An apparatus for the heat treatment of integral rotors 10 of gas turbines has a closable working space 12 which can be evacuated or filled with inert gas. Within the working space are a local heat source 18 such as an induction coil, a distance-measuring instrument 22 and a pyrometer. This arrangement allows local heating of the workpiece e.g. at a blade weld, and can be used to diminish or eliminate internal stresses introduced into a component through welding, without affecting the overall properties of the rotor. |
