HEATING ELEMENT AND WELDING KIT FOR RESISTANCE WELDING AND METHODS OF MANUFACTURING A HEATING ELEMENT AND WELDING THERMOPLASTIC COMPONENTS
20230059422 · 2023-02-23 ·

A heating element for resistance welding of thermoplastic components includes an electrically conductive sheet with cut-outs, wherein a ratio of cut-outs to electrically conductive sheet changes at least along a transverse direction of the sheet, so that an electrical resistance of the sheet has a maximum at a center of the sheet. A welding kit includes the heating element and an electrical insulation layer. A method of manufacturing the heating element, and a method of employing the heating element for welding two thermoplastic components to one another are disclosed.
