A Review on Optimization of Mechanical Properties for Aisi 1020 on Mig Welding

Welding is a manufacturing process, which is carried out for joining of metals by Metal Inert Gas (MIG) welding. This is the one types of Gas Metal Arc Welding (GMAW), in which Argon and Helium is used as a inert gas. Shielding gas Argon and Helium is used and consumable electrode is used which also plays role of conductor. MIG welding is versatile, gives very little loss of alloying elements and can be operated as semi as well as fully automated. All welds will be prepared by MIG welding technique. We studied Design of Experiments for this work and by use of the experimental data have optimize by any one optimization techniques which has decide later. In which inputs parameters for MIG welding are welding current, arc voltage and welding speed and the output parameter are hardness, tensile strength. We use AISI 1020 or C20 material for welding. It is plain carbon steel and also known as “soft” or mild steel. Small scale trial welding experiments, in the light of field joint of plate have been planned to perform on 5 mm plate thicknesses of low alloy steel AISI 1020 or C20 and double V-groove joint is used. For Experimental design I will use full factorial method (L=mn) to find out numbers of reading. To find out percentage contribution of each input parameter for obtaining optimal conditions, I will use manually method. I will make a mathematical model regarding to different input parameter values by using of gray relational analysis optimization
