Latest Developments in MIG Welding - A Review

Abstract: By continually supplying a wire electrode and a shielding gas to protect the weld pool from air contamination, MIG welding has been used to combine two metals or alloys. In comparison to other traditional techniques of combining the alloys using straightforward arc welding processes, the delivery of inert shielding gas provides a number of advantages. Better tensile strength, finer grain hardness, high weld quality and appearance, microstructure improvement, and metallurgical characteristics over the parent metal are a few advantages of this welding process. Therefore, the main goal of this research is to analyse current developments in the MIG welding industry and shed light on those areas that have not yet reached their full potential. As a result, various MIG welding stories are gathered and examined in this study paper based on tests, parameters, and the types of materials used for welding. According to the majority of the publications cited, current was discovered to be the dominant parameter among them, however gas flow rate and angle of weld using modern techniques have not been employed up to that level. Some suggestions for the manufacturing industries are noted below based on the evaluation, which may prove helpful for industrial applications in the future.
