Abstract

The point of the exploration review was to examine of divergent obstruction spot welding (RSW) process on austenitic tempered steel (304 grade) and austenitic hardened steel (AISI 202 grade) is concentrated tentatively. According to a process by using 304 stainless steel is smart choice for your cost effective in comparison to other materials, due to its durability, ease of fabrication and cleaning, corrosion resistance to oxidation. The impact of cycle boundaries, for example, welding current, welding time, welding pressure and electrode force on elastic shear strength of obstruction spot welded joints are explored with reaction surface approach (RSM). Taguchi method of design experiments was applied. This research work presents the high strength and high corrosive applicants use 304 instead of 202 are used as applications such as kitchen sinks, railway bogeys, automobile trim, chemical containers. The combination of AISI 304 and AISI 202 joined together to give the accompanying outcomes is not done before with this combination and composition, this is the Novelty of this research To achieve corrosion resistance using low grade carbon steel experimental test where taken for samples such as hardness test, tensile shear strength test and morphological characteristics on scanning electron microscope (SEM) where analysed.
