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.

What will I learn?
Gain practical insights into welding metallurgy to minimise cracking, manage hardness, and boost weld reliability. Understand thermal effects on microstructure, hydrogen and stress-induced failures, and implement preheat, PWHT, consumable choices, joint designs, machining, and testing to avoid defects and prolong part lifespan.
Elevify advantages
Develop skills
- Control weld hardness by adjusting microstructure to avoid cold cracking in shafts.
- Prevent hydrogen cracking through preheat management, diffusion control, and low-hydrogen consumables.
- Minimise weld and machining stresses via optimal joint design, toe finishing, and sequencing.
- Conduct weld failure investigations by choosing tests, mapping hardness, and analysing fracture surfaces.
- Choose welding processes and fillers to match AISI 4140 shafts for strength and toughness.
