A fixed coil induction heater produces quality thermoplastic fusion welds in prefabricated resin composite parts. A susceptor along a bondline between parts aligns with the induction coil segments of a solenoid induction coil along the centerline of the coil. Energizing the coil heats the susceptor to form the weld at the bondline. For this operation, our induction heating workcell uses complementary dies that define a central cavity with an oval pattern of induction coil segments roughly conforming to the shape of the cavity and surrounding all faces of the cavity where we position the preform composite parts and susceptor.
