Optimization of resistance spot welding process parameters on shear tensile strength of SAE 1010 steel sheets joint using Box-Behnken design

In the present investigation,sae 1010 steel sheets are welded by resistance spot welding. the welding current,welding cycle and electrode force are the principal variables that are controlled in order to provide the necessary combination of heat and pressure to form the weld. response surface methodology (box-behnken design) is chosen to design the experiments. in the range of process parameters,the result shows that as welding current increases shear tensile strength decreases,whereas welding time (cycle) and electrode force increase shear tensile strength increase. from the anova table it can be concluded that electrode force is contributing more and it is followed by welding time and welding current. optimum values of welding current (6 ka),welding time (25 cycle) and electrode force (4.5 kn) during welding of sae 1010 steel sheets joint to maximize the shear tensile strength (predicted 8.214 kn) have been find out. there was approximately 6.12 % error was found between experimental and modeled result. © 2016 jordan journal of mechanical and industrial engineering. all rights reserved.
