Abstract
Dissimilar arc stud welding is one of the most important tasks in manufacturing processes used to join the various metals with different dimensions. In the present work, AISI 304 austenitic stainless steel studs were joined to AISI 1008 low carbon steel base plate using an arc stud welding technique. The quality performance of the weld joint was analyzed employing the bending and torque test. A range of welding current and welding time were used to elucidate the effect of welding parameters on weld quality corresponding to bending and torque strength. The statistical method based on the Taguchi technique was applied for determining the optimum parameters. The results revealed that welding time play important role in arc stud welding followed by welding current. The actual torque of 90 N.m can be obtained according to the optimum condition for the stud welding by using (DOE) at 600 AMP and 0.3 second.
