Abstract :

Nowadays welding is the most important and the most common joining processfor Metals (and sometimes other metals). Among the existing methods for welding, ressistance welding uses heat and pressure simultaneously, In this thesis, effect of the process parameters on torsional strength of resistance projection welds in sheet metal and nut with different thickness has been investigated. Welding time, welding current and electrode force are the most important factors affecting the quality of a the weld. The Minitab16 software and response surface method have been used to conduct experiments to find the effect of the above parametrs on torsional strength.
