Current Status and Development of Submerged Friction Stir Welding: A Review

Submerged Friction Stir Welding is a modification of the friction stir welding process in which the water as the coolant is employed to standardize the temperature. It is considered as a green and environmentally friendly welding technology because of low energy consumption, no gas emission, and no need for consumable material. It is applied to structural purposes like oil platforms and pipelines, or in industrial and laboratories for enhancing the weld strength. This review paper is classified into three categories, the first one studies the preceding experimental investigations, the second one is modelling/optimization, and the third one is current status and development of submerged friction stir welding. The experimental results of the previous research findings in submerged friction stir welded sample with performance characteristics, tensile properties, microhardness, fracture analysis and corrosion resistance, macro/microstructure analysis on the various materials are discussed. This review articles concludes with recommendations for future research exertion.

Automated summary

Submerged Friction Stir Welding is an environmentally friendly welding technology that uses water as a coolant to standardize temperature. It is widely applied in structural, industrial, and laboratory settings for enhancing weld strength.
