Plasma Arc Welding (PAW) is one of the important arc welding process commonly using as aerospace, medical, power plants, and automobile industry. Especially stainless steel 316L (SS316L) has been successfully utilized in many sectors because of its excellent corrosion resistance, self-healing property, and biocompatibility, high fatigue life and creep resistance. The paper focuses on weld quality characteristics like weld bead geometry, grain size, hardness and ultimate tensile strength of PAW welded joints of austenitic stainless steels AISI 316L. From the analysis carried out it is noticed that AISI 316L has achieved sound weld bead geometry, good tensile strength and hardness. Welding of Low Nickel Chrome-manganese Austenitic is an emerging area of research. Due to nickel price volatility, there was been increased interest in no-nickel or low-nickel economical grades of stainless steel. Chrome -manganese austenitic (“standard 200-series”) and ferritic stainless steel (“standard 300-series”) grades with well-defined technical properties have proved acceptable materials for specific applications for many years. This increase in the use and production of these low nickel grades is not currently matched by a proper level of user knowledge. So there is a risk that they may be used in unsuitable applications. It is very important to cultivate the method of fabrication like welding. This paper looks at the behaviour of low nickel chrome-manganese austenitic stainless steel in terms of microstructure and sensitization effects upon welding by PAW process. In this project, we performed 5 mm thick AISI 316L bead-on and joint using PAW. Further study the geometric analysis, microstructure, micro-hardness, tensile strength, SEM analysis and TAGUCHI analysis of the welded workpieces and analyzed the benefits and shortcoming methods.
