  • WELDING AUXILIARY JOINING PART WITH A PLASTICALLY DEFORMABLE TIP REGION; METHOD FOR CONNECTING COMPONENTS WITH THIS WELDING AUXILIARY JOINING PART
    Publication number: 20150144602
    Abstract: A welding auxiliary joining part in the shape of a stud having a head, a shank and a tip is disclosed. The welding auxiliary joining part is driven into a component made of a non- or poorly weldable material by means of a setting method. A welding head is created during driving-in due to mechanical deformation such that subsequently the component can be connected by welding via the welding auxiliary joining part to a further component made of a weldable material.
