Influence of the activating flux on weld joint properties at arc stud welding process

In this paper, the influence of the activating flux 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 was performed, with the application of the activating flux for ATIG process. In order to evaluate the influence of the activating flux on the welding process parameters variations, the main welding parameters were monitored by an on-line monitoring system. Besides monitoring of welding current and voltage, the influence of the activating flux on the weld joint appearance was investigated. The macrosections of the weld joints welded with the same parameters, but with and without the presence of activating flux are shown.
