Welding Metallurgy and Welding Technology

Welding Metallurgy and Welding Technology provides a comprehensive understanding of welding processes, metallurgical principles, materials, and practical welding applications. The course explains how heat input, cooling rates, and welding parameters influence the microstructure and mechanical properties of welded joints. Participants learn about common welding processes such as SMAW, GMAW, GTAW, FCAW, and SAW. It covers weldability of carbon steels, stainless steels, alloy steels, and other engineering materials. The course introduces welding consumables, electrodes, filler metals, shielding gases, and their selection criteria. Participants understand common weld defects, their causes, prevention, and inspection methods. Welding procedures, WPS, PQR, welder qualification, and essential quality requirements are also discussed. The course covers heat-affected zones, residual stresses, distortion, preheating, and post-weld heat treatment. It also provides an overview of welding inspection and testing techniques used to assess weld quality. Overall, the course helps engineers and professionals develop practical knowledge for effective welding design, production, inspection, and quality control.
