STUD WELDING OF HIGH STRENGTH STRUCTURAL STEELS

Tests were carried out on stud welding with lift-off ignition of high strength steels such as the fine-grained structural steel StE 690. This material is not allowable for stud welding in terms of the building regulations. Welding of the material St 52-3 by stud welding has already led to hardening in the weld- and heat-affected zones. Various methods for heat treating studs and plate as well as a method for postheating the welded joint were investigated. The objective was to diminish the cooling rate and hence the tendency to hardening of the stud-welded joints. In addition, the effect of hydrogen, induced through the ceramic ring, on the welded joint was also evaluated.
