Arc Stud Welding used to weld studs (electrodes) to base metal directly, has continued to grow recently because of its applications such as, in automotive constructions, steel frameworks, containers and assembling electrical panels. In this research, stud arc welding of Nickel-base alloy with stainless steel (stud) was investigated. Main welding parameters were used; welding current and welding time at constant protrusion. Three levels of welding current (400, 600 and 800A) and fourteen levels of welding times (0.1-0.75 second). The effect of the selected parameters on mechanical properties was studied. It was shown that dissimilar welding of ASTM Inconel 600 to steel stud AISI 431 recorded higher torque strength of 85.74 Nm
