Welding Metallurgy Training
This course equips you with essential welding metallurgy knowledge for shafts and flanges. Explore how heat input, microstructure changes, machining practices, and residual stresses cause cracking, and master prevention strategies including optimised procedures, filler metals, preheat, PWHT, and thorough inspections for dependable welds that stand up to tough conditions.
