Welding Metallurgy Training
Master welding metallurgy for shafts and flanges in this hands-on course. Discover how heat input, microstructure changes, machining practices, and residual stresses cause cracking, and learn prevention strategies using optimised procedures, filler metals, preheat, PWHT, and thorough inspections for dependable weld results.

What will I learn?
Gain practical insights into welding metallurgy to minimise cracking, manage hardness, and boost weld reliability. Understand thermal cycle effects on microstructure, hydrogen and stress-induced failures, and implement preheat, PWHT, consumable choices, joint designs, machining, and testing to avoid defects and prolong component lifespan.
