Effect of Process Parameters on Quality of Seam Welded AISI 304L | Original Article
Resistance Seam welding is one of the most commonly used methods for joining of two faying surfaces of metal sheets in automobile industries for producing leak proof joints. It is a process in which heat is produced at the joint by resistance to the flow of current. The aim of the work was to study the influence of process parameters on tensile strength of resistance seam welded joint for AISI 304L Stainless steel. The experimental studies were conducted under varying the electrode current, electrode force and heat time. Taguchi’s experimental design method was used for setting of process parameters. Signal to noise ratio (S/N) was used to obtain combination of optimum welding parameters and analysis of variance (ANOVA) for determining the most dominating parameter which affects seam welded quality.
