The final assignment is about influence of basic welding parameters on quality and appearance of projected welding joint at the process of resistance projection welding of 3 mm thick stainless wires. The basics of electrical resistance welding are first presented with emphasis on projection and spot welding. The parametric analysis of resistance projection welding was performed, where we were changing main welding parameters. We used C0 cooper rod electrodes. The samples were visually inspected, and the manual torsion test was performed. We found out, that correct settings of basic welding parameters is very important in resistance projection wire welding, to achieve welds that are acceptable in terms of strenght as well as visually. For our welding example where we use 3 mm thick stainless-steel wires, we achieve the most suitable welded joint with the parameters: electrode compression force 25 N, current welding strenght 80 kA and welding time 0,117 s.
