The study focused on the standalone TIG and MIG welding and the combined effect, emphasizing the microstructural properties and strength of the welded joint, especially the heat-affected zone. The literature study revealed that both welding techniques and their combination have full penetration in terms of the weld, and the HAZ for TIG-MIG has a larger width in comparison with TIG and MIG. TIG-MIG joints usually demonstrate ductile fracture compared with standalone MIG or TIG welded joints. However, it is characterized by adequate properties like tensile strength compared with the TIG and MIG welding processes. In addition, a comparison between the TIG-MIG techniques and the traditional MIG welding revealed a refined appearance in the joint, as revealed by several microstructures of the joints.
