Method For Joining Joining Parts And Joining Tool

A method for joining parts associated with an airbag firing channel with a cover part, comprising the steps of:

• providing, in a preparation step, a first joining part having a first surface, a second joining part having a second surface, and a joining tool;
• arranging, in an arrangement step, the first joining part at a distance to the second joining part so as to form an intermediate gap between the first joining part and the second joining part, and arranging a joining tool in the intermediate gap between the first joining surface and the second joining surface, the joining tool comprising at least one infrared emitter and at least one heating element;
• melting and/or plasticizing, in a melting step, the first joining surface with the at least one infrared emitter and the second joining surface with the at least one heating element, and
• pressing, in a joining step, the melted and/or plasticized first joining surface against the melted and/or plasticized second joining surface with a joining pressure force so as to form a joined assembly, and cooling the joined assembly to form a material-locking joint between the first joining surface and the second joining surface.
