Pressing device for pressing a metal foil on a bearing surface, welding device, method for welding a metal foil and component with at least one metal foil

摘要

The invention relates to a contact pressure device for pressing a metal foil (12) onto a bearing surface (14), in particular when welding the metal foil (12) to a magnetic module (10), wherein the magnetic module (10) is arranged to generate a pulsed magnetic field (10). 46) in such a way that in the metal foil (12) an eddy current (48) is directed directed such that the metal foil (12) is pressed against the support surface (14). The invention further relates to a welding device (1), in particular a laser welding device, with a welding module for welding a metal foil (12) in a welding process and the pressing device, and a method for welding a metal foil (12), the metal foil (12) resting on a bearing surface (14) is pressed, wherein a pulsed magnetic field (46) is generated such that in the metal foil (12) an eddy current (48) is directed directed such that the metal foil (12) is pressed against the support surface (14). The invention further relates to a component with at least one metal foil (12) which is welded by the method according to the invention.
