Popis:	Dissimilar metals welding using shielded metal arc welding (SMAW) has been widely used in various industries such as automotive, maritime, transportation, and offshore structures. In this work, the Taguchi approach was applied for improving the tensile strength of dissimilar welding between AISI 4340 steel and 304 Austenitic stainless steel. The effects of four welding factors: electrode type, welding current, joint type, and welding speed on the tensile strength were studied. The various factors were assigned to an L9 orthogonal array, and analysis of variance (ANOVA) was utilized to determine a significant contributing factor. It was found that electrode type and current welding factors significantly affect tensile strength. The optimum condition parameters for tensile strength were achieved with an electrode type (E309), welding current (110 A), joint type (II), and welding speed (2 cm/min).
