Welding Metallurgy Training
This course teaches welding metallurgy for shafts and flanges, covering how heat input, microstructure changes, machining, and residual stresses cause cracking. Students learn prevention strategies including smart procedures, filler selection, preheat, post-weld heat treatment, and inspection to ensure reliable welds and longer component life.

What will I learn?
Gain practical knowledge in welding metallurgy to minimize cracking, manage hardness, and boost reliability. Understand thermal cycle effects on microstructure, hydrogen and stress-induced failures, and apply techniques like preheat, PWHT, consumable choices, joint designs, machining controls, and testing to avoid defects and prolong part lifespan.
