The objective of this article is to review the TIG/MIG welding technology and its application in improving the microstructural, mechanical and metallurgical properties of engineering materials. It is shown that the TIG/MIG hybrid process is very effective in improving the mechanical and metallurgical properties of welded structures compared to independent welding processes. Combining the positive properties of individual welding process in the same weld pool is a novel technology. However, more studies reveal that Hybrid MIG-TIG process has not been extensively researched despite its promising benefits. The optimization of its process parameter is not fully understood. Its processes and applications are still limited. Most studies either focus on experimental investigation limited to the geometric properties like tensile and hardness properties. The TIG/MIG hybrid welding method has not been used to solve fatigue and its related problems of steel components in the structural industries. Just a few numerical analyses are done. Extensive work has not been done on the mechanical, metallurgical and corrosion properties of the hybrid. Information on the thermal behaviours and temperature distribution is also lacking. Hence, there is a need to research the TIG/MIG hybrid welds and perform numerical modelling to validate the results using experimental data.
