The review focused on the applications of tungsten inert gas a (TIG) metal inert gas (MIG) welding processes. Each of the welding process was critical studied to understand the operations and the need to maintain safety and reliable weld with adequate mechanical properties. In addition, the various applications in the aerospace, aeronautic, automotive and food packaging industries were critically highlighted. However, there potentials as well as problems highlighted have been critically reviewed and reported especially porosity which usually result into hole defects at the weld joint as well as plastic deformation due to the frictional heat induced have been reported in this study. Furthermore, the study further recommended friction stir processes integrated with TIG/MIG welding as an alternative method that will solve the problems associated with fatigue behaviour of welded joint.
