Influence of welding conditions on resistance flash welds

The contribution gives an insight into resistance flash welding with emphasis on process dynamics. For the experiments ribbed mild steel concrete reinforcement bars were used with a range of welding parameters used in a normal welding praxis. The welded bars were tested for tensile strength and the results were used to develop a regression model. The model was designed to predict weld piece strength according to input welding parameters. The input welding parameters were: welding force, welding current and welding time.
