Dissimilar Arc Stud Welding AISI 304/ AISI 1008: Mechanical Properties

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.

“…Tensile strength and fracture mode Figure 3b presents the tensile strength of the samples processed at 400 A and different welding times 0.1, 0.2, 0.3, 0.4, 0.5, 0.6 sec. The mean A similar result was reported by Hameed et al [23], which they performed bending test of AISI 304 screw stud using arc stud welding. The successful results were obtained for current and time values (400 A, 0.25 sec), (600 A, 0.3 The joint performed using welding current of 400 A and welding time 0.4 s shows a highest mean tensile strength of 583 MPa which is considered as a preferred process parameter.…”
