Patent abstract
A welding auxiliary joining part with which a welding connection, more particularly a resistance welding connection, can be established between a first component A made of a poorly weldable material and a second component made of weldable material. The welding auxiliary joining part is distinguished by a cylindrical punch shaft that can be punchingly pressed into the first component A approximately rotation-free. The punch shaft has an element head at the head underside of which only one continuous circumferential clamping ring is arranged that projects axially in the direction of the punch shaft.
