Abstract
An apparatus and method for heat treating the welded area of a repaired gas turbine engine component uses first and second heating elements. The heating elements each include an insulating tube supported by a support rod and wrapped with a conducing wire. One of the heating elements is sized to fit inside a recess in the gas turbine engine component, adjacent to the welded area, while the second heating element is placed outside the recess, but also adjacent to the welded area, thereby heating the welded area from two sides.
