Activating flux application at stud arc welding in bridge constructions production

An application of activating flux at arc welding processes can result with significant penetration improvement. This paper presents experimental investigation of activating flux application at arc welding processes. Special emphasis is put to stud arc welding processes in bridge constructions and steam boiler thermal insulation production. Besides welding param¬eters, the authors provided photographs of appropriate cross-section of weldments.
