    Abstract: A system and method inductively heats and stress relieves a weld joint area having a stress induced zone. A susceptor assembly is positioned over the stress induced zone. The susceptor assembly includes susceptor sheets manufactured to operate at different, preselected Curie temperatures. A housing is mounted over the susceptor assembly including an induction coil positioned adjacent to the susceptor assembly. An alternating electric current is applied to the induction coil. The alternating electric current causes the induction coil to generate a plurality of magnetic flux lines. The invention provides the advantage that the magnetic flux lines passing through the susceptor assembly heat the susceptor assembly providing localized and controlled temperature heat to the weld joint area to stress relieve the stress induced zone.

    Abstract: An apparatus and method for heat treating a structural member, for example, to relieve stresses therein, are provided. The structural member is restrained in a die cavity by one or more inflatable bladders so that a desired dimensional accuracy is achieved. The structural member can be heated by an electromagnetic field generator, such as an induction coil, that heats one or more susceptors to a characteristic Curie temperature. The apparatus can be used to process structural members of various sizes and shapes, and the heating and cooling cycle can be performed relatively quickly.
