Abstract

See full text

Quality thermoplastic fusion welds are formed in prefabricated resin composite parts by aligning a susceptor along a bondline between parts 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 users complementary dies that define a central cavity with an oval pattern of induction cool segments surrounding all faces of the cavity where the preform composite parts and susceptor are positioned.
