Classification: CPC B | IPC B

Claim 0:
1. A method of joining a first workpiece to a second workpiece, the method comprising:
induction welding the first workpiece to the second workpiece, wherein a first side of the second workpiece at least partially overlays a first side of the first workpiece, wherein the first workpiece is a first thermoplastic composite structure, wherein the second workpiece is a second thermoplastic composite structure, wherein the induction welding comprises:
locating a non-ferrous metallic strip proximate a second side of the second workpiece, wherein the non-ferrous metallic strip is configured to conduct heat uniformly at a welding region between the first side of the second workpiece and the first side of the first workpiece, wherein the non-ferrous metallic strip comprises at least one of copper, aluminum, gold, or silver, and wherein the non-ferrous metallic strip is a mesh;
locating an induction welding tool proximate the non-ferrous metallic strip; and
locating a coil proximate a second side of the first workpiece,

wherein the induction welding is at the welding region, and wherein the induction welding further comprises:
operating an induction welding tool at the welding region, wherein the induction welding tool comprises an induction welding tool surface; and
energizing the coil proximate the first workpiece, wherein the coil is configured to energize with an electric current, wherein the energized coil is configured to generate an electromagnetic field that induces the electric current which heats the first workpiece and the second workpiece at the welding region, wherein the heat generated by the coil is configured to weld, by the induction welding tool, the second workpiece to the first workpiece at the welding region.
