Abstract
Susceptors for induction heating for use in thermoplastic welding are tailored to provide precise control of the heat applied to the weld and especially to control overheating at the edges of susceptor. The preferred susceptor has a central portion having a uniform pattern of substantially similar openings and selvage edge strips devoid of openings to provide a low impedance current path for eddy currents at the edges. We can create aerospace structure, particularly a wingskin-spar assembly, without fasteners.
