ARC STUD WELDING 

WITH CERAMIC FERRULE OR

SHIELDING GAS  

Drawn arc stud welding with shielding gas or with ceramic ferrule is especially suitable when high demands relevant to safety regulations are made on the welding quality. Owing to the increased weld penetration of approx. 1-3 mm, this method is mainly used for workpieces with a minimum thickness of 2 mm. Drawn arc stud welding generates high-quality welded joints. The stud face is completely and perfectly welded to the workpiece. The application of this welding method has proven very successful e.g. in structural steel engineering, mechanical engineering, shipbuilding, building construction and civil engineering, power plant construction, boiler construction, apparatus engineering, insulating engineering, reinforced concrete construction etc. Short-cycle drawn arc stud welding is a variant of drawn arc stud welding. Owing to the low weld penetration of approx. 0.4 mm, this method can even be applied on sheet metals with a minimum thickness of 0.6 mm. When correctly adjusting the welding parameters, this welding process guarantees particularly safe, uniform and reproducible stud welded joints. Test welds have to be carried out when using workpieces with difficult surface characteristics.
