Özet

In this study, commercial titanium (Grade 2) plates, which are commonly used in aviation, space and chemistry industries because of its low density, high resistance and perfect corrosion resistance, are jointed by using spot resistance welding. In the process, the effect of welding parameters on tensile strength using different electrode strengths (3 and 6 kN), welding current (3, 5 and 7 kA) and welding time (10, 20 and 30 cycles). The results of tensile strength test were optimized with the characteristic of maximum-best control of Taguchi method. Optimum test combination for maximum tensile strength was designated as A2B3C3 (6 kN-7 kA-30 cycles). Effects of welding parameters on tensile strength results were analyzed with analysis of variant (ANOVA) method and the most effective parameter was determined as welding current with %45.82.
