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： 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).

摘要： An assembly is provided for induction welding. This assembly utilizes a heat shield (e.g., a mica heat shield) with a recess. An induction welding coil may be disposed within this heat shield recess during induction welding operations. The wall thickness of the heat shield within the recess may be reduced to enhance heat transfer to a workpiece during induction welding operations. Members may engage the heat shield on opposite sides of the recess (and that have an increased wall thickness) to support both the heat shield and the workpiece during induction welding operations, during which a biasing force may be exerted on both the heat shield and workpiece.

摘要： During a manufacturing method, an induction welder is provided that includes a concentrator and a coil. The concentrator includes a receptacle and a face surface. The receptacle projects vertically into the concentrator from the face surface to an end of the receptacle. The receptacle extends laterally within the concentrator between opposing sides of the receptacle. The receptacle extends longitudinally within the concentrator along a centerline. The coil is seated and extends longitudinally along the centerline within the receptacle. A first thermoplastic body arranged with a second thermoplastic body are provided. The first thermoplastic body is located vertically next to the face surface. The first thermoplastic body is induction welded to the second thermoplastic body. The induction welding includes: generating an electromagnetic field with the coil; and concentrating the electromagnetic field with the concentrator onto a region of the first thermoplastic body.

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 method for joining thermoplastic composite includes: providing a first part having a first joining surface disposed in a first plane and a second joining surface disposed in a second plane that is non-parallel to the first plane; providing a second part having a third joining surface disposed in the first plane and a fourth joining surface disposed in the second plane; disposing the parts so that the first and third joining surfaces are in contact with one another, and the second and fourth joining surfaces are in contact with one another; forcing the second and fourth joining surfaces against one another; and welding the first and third joining surfaces together using a vibration welding process, wherein the welding process and the forcing of the second and fourth joining surfaces against one another causes the second and fourth joining surfaces to be welded.

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.
