Abstract
An installation for welding a stack of parts made of thermoplastic composite materials (20) in a local welding plane (P), this installation including an electromagnetic induction head (8), pairs of elements for guiding and pressing the workpiece stack (20) in this local plane (P), and, on each side of the induction head (8), at least one pair of guide elements, each pair of guide elements having a lower guide element (14) and an upper guide element (10) that are superposed, receiving between one another the stack of parts (20) by guiding it in the direction perpendicular to the local welding plane (P).
Claims14
An installation for welding a stack of parts made of thermoplastic composite materials (20) in a local welding plane (P), the installation having an electromagnetic induction head (8) and, on each side of said induction head, at least one pair of guides (10, 14;
- 10′, 14′), each pair comprising, respectively, a lower guide (14, 14′) and an upper guide (10, 10′) that are superposed and are able to receive between them the stack of parts (20) by guiding in the direction perpendicular to the local welding plane (P),
- wherein at least one guide pair has a device for displacing the lower guide (14, 14′) or upper guide (10, 10′) with respect to the other in the direction of the local welding plane (P) and a system for regulating said displacement device according to the curvature of the stack (20) so as to ensure perpendicularity of the pressure with respect to the surfaces.
