SCALING ISSUES IN COMPOSITE JOINTS

than the single-step weld; and (2) uneven heating and overheating were minimized by reducing the heating element length within the bond region through the use of the sequential resistance welding process. The different welding techniques produce a large variation in lap shear strength; direct comparison of the weld quality and lap shear strength shows that the sequential resistance welding process yields a superior bond. With the principles developed in this investigation, resistance welding can be used to join largescale thermoplastic composite parts with consistent, high levels of performance and quality.
