Welding Metallurgy Training
Gain mastery in welding metallurgy for shafts and flanges. Understand how heat input, microstructure changes, machining practices, and residual stresses cause cracking, and learn prevention strategies using smart procedures, filler selection, preheat, PWHT, and thorough inspection to ensure reliable weld performance and longer component life.

What will I learn?
This practical course delivers essential knowledge on welding metallurgy to minimise cracking, manage hardness, and boost reliability. Discover how thermal cycles alter microstructure, the role of hydrogen and residual stresses in failures, and practical applications of preheat, PWHT, consumable choices, joint designs, machining controls, and testing to avoid defects and prolong component durability.
