Superalloy welding

Superalloy welding

When components are joined by the patented SWIP process (superalloy welding by inductive pre-heating) they are first heated to the material-specific welding temperature by induction. This permits the temperature gradient within the component to be reduced or adjusted as required. The component temperature is monitored and controlled using several non-contact pyrometers. The process is also suitable for materials that are otherwise difficult to weld. MTU uses the SWIP process mainly to repair damaged tips of high-pressure turbine blades in single-crystal materials.
