WELDING AUXILIARY JOINING PART, MATRIXES FOR PLACING THE WELDING AUXILIARY JOINING PART, A CONNECTION METHOD FOR THE WELDING AUXILIARY JOINING PART, AND PRODUCTION METHOD FOR THE WELDING AUXILIARY JOINING PART AND THE MATRIXES

摘要

The invention relates to various connecting methods for a welding auxiliary joining part having a head and a rounded point for setting in at least one first component having a matrix as a counter-bearing, which has a concave recess having an inner wall having an arc shape, at least in sub-regions, having a matrix radius MR in the range from 1.0 mm ≤ MR ≤ 60 mm, for preparing a subsequent welding method. The geometry of the welding auxiliary joining part and the matrixes meet the following condition: 0.001 ≤(A)≤ 0.1, in particular 00.002 ≤(A)≤ 0.08, wherein SR designates a point radius of the rounded point of the welding auxiliary joining part.
