Optimizing Hardness Measurements in Submerged Arc Welding of Ms-(Is:2062) Material: A Focus on Hardness Enhancement

Abstract
Hardness, specifically measured through the Brinell Hardness Test designated as HBW, is another critical mechanical property that directly relates to a material's resistance to penetration or deformation. In the context of the submerged arc welding (SAW) process optimization study, HBW played a significant role in assessing the hardness of the welded joints in Material MS-(IS:2062). The study focused on utilizing the Taguchi technique to adjust welding parameters effectively and enhance the hardness values of the welded samples. By optimizing factors such as current, voltage, and speed, researchers were able to improve the overall hardness measured in HBW units, indicating a higher degree of resistance to deformation in the welded joints. The successful application of the Taguchi method in predicting and achieving optimal HBW values highlights its effectiveness in optimizing process parameters to enhance mechanical properties, ultimately contributing to improved weld quality and material performance.
