Heat treatment influence on stud arc welding process characteristics

In this paper the influence of welding current and heat treatment (normalizing) on the weld joint area hardness changes at Drawn Arc Welding – DAW - process with a ceramic ferule is examined. The changes of weld joint characteristics before and after the heat treatment are investigated by micro-hardness HV0, 2 measuring across the weld joint and analysing the hardened zone by presentation in diagrams and through macro and micro section analysis of weld before and after the normalising process.
