Study of Metallurgical and Mechanical Properties in Submerged Arc Welding With Different Composition of Fluxes-A Review

Welding is most widely used in the manufacturing industry; submerged arc welding is one of the predominantly used joining process to join materials with a higher thickness to reduce the defects during welding. This welding process is preferable due to ease of automation, less skilled operator, high production rate and high efficiency. The quality of the joint is profoundly influenced by flux, and it is composition. In the present paper, a review has been reported on study the metallurgical and mechanical properties of the joint with different flux compositions. The flux composition is varied by adding other fluxing elements like MnO, Cr2O3, Ti2O3, MgO, etc., in the powder format to the regular flux (SiO2-Al2O3-CaO). The influence of each composition is discussed with merits, demerits, and mechanical properties are reported in the present study
