Analysis of Weld Characteristics of MIG Welded Aluminum 6063 Material: A review

Abstract

The welding procedure is formed by welding two or more work pieces (metal or plastic) according to a particular geometry. Welding is the main joining method for these materials. Many welding methods for Aluminium include tungsten arc welding (TIG), metal inert gas welding (MIG), laser welding, and friction stir welding (FSW) . Welding is a process of joining two metal pieces by the appliance of heat. Welding is that the least expensive process and widely used now a days in fabrication. MIG welding are often wont to join differing types of ferrous metals and non-ferrous metals that can't be welded by non-traditional welding processes. This welding process parameters was used during joining of metal and parameter like welding current, welding voltage, welding speed, nozzle distance, wire feed rate, gas flow and torch angle . Welding joints different metals with the assistance of variety of processes during which heat is supplied The main objective of this review is to study the MIG welding on Aluminium 6063. During this study the properties of MIG is used to weld Aluminum 6063. This method is an arc welding method in which electric spark is used to generate required thermal energy to fuse the metals.MIG uses CO2 gas to protect the weld pool .In this method a consumable feed wire is used in welding. In this paper,theAluminum 6063 was welded by butt joint by metal inert gas (MIG) welding process. Then various tests were conducted to the joints like lastingness , bending test,micro structural test, grain size test. And then with the final results, the physical and mechanical properties were investigated. Applications of mig welding are Saucepans ,nuts ,bolts screws, sanitary ware, tubing, food and pharmaceutical production equipment ,springs ,sinks and splash backs ,architectural paneling.
