摘要： An assembly is provided for induction welding. This induction welding assembly includes a fixture. The fixture includes a first support structure and a second support structure. The second support structure includes a frame and a plurality of trunks. Each of the trunks is connected to and repositionable on the frame. The fixture is configured to secure a workpiece vertically between the first support structure and the second support structure using the trunks during induction welding of the workpiece.

摘要： During a manufacturing method, an induction welder is provided that includes a concentrator and a coil extending through a receptacle in the concentrator. The receptacle projects into the concentrator from a face surface of the concentrator. A first thermoplastic body arranged with a second thermoplastic body are provided. The first thermoplastic body is located next to the face surface. The first thermoplastic body is induction welded to the second thermoplastic body to provide a weld seam between the first thermoplastic body and the second thermoplastic body. The concentrator extends along a portion of the weld seam. The induction welding includes: generating an electromagnetic field with the coil; and concentrating a portion of the electromagnetic field with the concentrator onto a region of the first thermoplastic body.

摘要： An assembly is provided for induction welding. This assembly utilizes a plurality of heat shields (e.g., mica heat shields) that are aligned/disposed in end-to-end relation, with each such heat shield having a recess. An induction welding coil may be disposed within a heat shield recess during induction welding operations and is movable along a welding path while proceeding along the recesses of the various heat shields. This welding path may be axially extending or may be curved. The induction welding assembly may be used to induction weld a stiffener to a curved skin or shell, for instance where a base of the recess for each heat shield is curved such that the induction welding coil may be moved along a curved welding path and while maintaining a constant spacing between the induction welding coil and the recess base of the various heat shields.

摘要： An induction welding system includes a first gantry, a second gantry, and a support structure. The first gantry includes a first frame and a first plurality of trunks. The first plurality of trunks defines a first curved inner support surface of the first gantry. The first curved inner support surface has a first curvature geometry. The second gantry includes a second frame and a second plurality of trunks. The second plurality of trunks defines a second curved inner support surface of the second gantry. The second curved inner support surface has a second curvature geometry which is different than the first curvature geometry. The support structure includes at least one tooling member defining a curved outer support surface of the support structure. The support structure is longitudinally moveable relative to the first gantry and the second gantry.

摘要： A welding assembly is disclosed. The welding assembly includes a plurality of separately controllable actuators (e.g., pneumatic, having an axially movable ram) to press a corresponding portion of a first workpiece (e.g., a discrete flange of a first stiffener) against a second workpiece (e.g., an outer skin) for welding operations (e.g., via induction welding).
