Examination of welding parameters influence on Stud Arc Welding process

It is well known that the quality of welded joint depends on good selection of welding parameters, and their application during welding process. Also, one can mention, that the stud arc welding process involves the same electrical, mechanical and metallurgical principles as other arc welding processes. As the application of stud welding process is established in many production areas (steam boiler production, bridge construction, automotive and appliance industry), in this paper, the influence of the welding parameters on the weld joint properties at the drawn arc stud welding process with ceramic ferrule is analysed. In the experimental part of the paper, the arc stud welding process is applied with the different welding time and the application of the activating flux for ATIG process (applied with a brush, as a suspension, on the base metal surface). The macrosections of the weld joints welded with different parameters are shown.
