PCT No. PCT/EP91/01950 Sec. 371 Date Apr. 16, 1993 Sec. 102(e) Date Apr. 16, 1993 PCT Filed Oct. 15, 1991 PCT Pub. No. WO92/06814 PCT Pub. Date Apr. 30, 1992.In order to be able to weld on studs (2) with a larger than normal diameter, a stud-welding process is proposed in which the pressure applied to the stud (2) before the welding current is triggered is applied symmetrically to the stud axis (A), but extra-axially and adjustable as appropriate, thus ensuring better centering during the welding operation and also improving the quality of the weld. A suitable pressure-application device (27) is proposed for this purpose.
