| Abstract | ||
| There is a strong interest in the use of aluminum alloy sheet for vehicle applications, particularly the body, where resistance spot welding is the principle joining method. The resistance spot welding (R.S.W) quality has a great effected by the process variable such as, welding current, welding time, and electrode pressure beside other variable such as material thickness and type and electrode diameter. In this work the effect of process variable on welding quality was investigated. Trials were conducted on 1.2 mm thick 2014 – O aluminum alloy sheet. The tensile shear strength was used as primary index of welds quality. Experimental investigation show that the best current is 45 KA, best time is 10 cycle, and electrode pressure of 3 KN . | ||
