A narrow susceptor is incorporated into the die in the vicinity of a bondline between two or more parts in an induction heating workcell. When the induction coil of the workcell is energized, the susceptor heats and preferentially heats the parts near the bondline. The preferential heating is localized at the bondline and reduces energy losses otherwise expended to heat large thermal masses in the workcell or to heat the entire parts.

A method for joining large metal aerospace structure made by joining two workpieces using localized induction heating provided by an induction coil to heat the structure along a bondline to a joining temperature to reduce processing time and energy consumption, comprising the steps of: (a) assembling at least two workpieces to define an assembly having a joint interface at the bondline to form the structure; (b) placing the assembly in an induction heating press with the bondline adjacent a surrounding ribbon coil susceptor susceptible for induction heating and incorporated into a wall of a die adjacent the joint interface; (c) energizing the induction coil to heat the susceptor and thereby to heat the workpieces locally at the joint interface; (d) applying pressure by pushing the workpieces together laterally when the bondline reaches the joining temperature to produce a jointed part having a geometry; (e) monitoring the geometry of the joined part; and (f) de-energizing the coil.
