The disclosure is related to various connecting methods for a welding auxiliary joining part having a head and a rounded tip for setting in at least one first component having a die as counter-bearing, which has a concave recess with an inner wall having at least in sub-areas an arc shape and 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 die meet the following condition: 0.001 ≤ SR MR ≤ 0.1 , in particular 0.002 ≤ SR MR ≤ 0.08 , wherein SR designates a tip radius of the rounded tip of the welding auxiliary joining part.
