Abstract
In the past years so many developments and innovation are made to increase the performance of the
welding machine by reducing the power consumptions, cost, labour skills and many more. In a row, AMIG welding process is one of the welding processes which increase the welding properties of material
at the same consumption of the power and resources. A-MIG welding is wildly used to optimize the
parameter of MIG welding. A steady flow welding power gracefully delivers electrical vitality, which is
directed over the bend through a segment of exceptionally ionized gas and metal fumes known as
plasma. Metal inert gas (MIG) welding is most regularly used to weld thick segments of tempered steel
and non-ferrous metals, for example, aluminum, magnesium, and copper compounds. Three sorts of
oxides, Fe2O3, SiO2, and MgCO3, were utilized to research the impact of initiating transition helped gas
metal bend welding (GMAW) on weld dab math, precise twisting and mechanical properties. The most
noteworthy impact on the inward structure factor was knowledgeable about instance of MnO dynamic
transition, which diminished the inside structure factor by 20 %. If there should arise an occurrence of
the outside structure factor the applied SiO2 dynamic transition caused the greatest increment which is
37 %. In the hardness dispersion and the microstructure of the joints, including the weld metal and the
heath influenced zone, no critical contrasts were experienced contrasted with the example welded with
no transition material.
