Abstract :

MIG/MAG process is widely used for faication of wide variety of materials. This process is widely used because it can be applied for all welding positions. Industries as well as researchers are engaged to improve the properties and quality of the welded joint. The selection of the shielding gas is a very typical work because it effect the mode of metal transfer, inclusion volume, melting rate of electrode, current setting etc. Lot of research work has been done regarding the effect of shielding gases on the welded joint characteristics on the MIG/MAG process. Based on the study of various works, the present paper provides a review of the effect of Ar+CO2 and Ar+CO2+O2 (with different quantities) on the mechanical properties, inclusion and microstructure.
