Mathematical & Computational Analysis of Process Parameters in Gas Metal Arc Welding of Austenitic Stainless Steels: A Review

Abstract

Since, the transition of human civilisation from stone age to metal age, metals and alloys have become the inevitable parts of human life. Since its invention, steel has been a material of prime importance in the field of fabrication. With the addition of various types of impurities in various compositions, thousands of varieties of steels are formed. These alloys, thus, find wide range of applications in our day to day life and engineering applications as well. Moreover, with the advent of arc welding technique in mid-1800s, manufacturing got even easier and diversified. MIG welding, also known as Gas Metal Arc Welding (GMAW), is a special kind of arc welding, developed later, in which inert/active gases are used. It is a more user friendly and robust technique, which has got wider range of applications and thus, increased industrial production rates by manifolds. Accordingly, over the period of time, both steels & MIG welding technique have captured the attention of researchers across the globe and generated the curiosity among them to explore these manufacturing gems more deeply. Nevertheless, with the consideration of various input & output process parameters as well as application of various mathematical & computational techniques, research has become more precise and easier. In this investigation work, the authors have tried to compile the various input/output process parameters and computational & mathematical research tools employed to explore the various facets of MIG welded Austenitic Stainless steels and further research prospects thereof.
