Welding Metallurgy Training
Master welding metallurgy fi shafts an flanges. Learn how heat input, microstructure, machining, an residual stress cause cracking—an how fi prevent it wid smart procedures, filler choices, preheat, PWHT, an inspection fi reliable weld performance. Dis course gi yuh di knowledge fi reduce cracking, control hardness, an boost reliability.

What will I learn?
Dis short, practical course gi yuh clear, actionable knowledge bout welding metallurgy so yuh can reduce cracking, control hardness, an improve reliability. Learn how thermal cycles change microstructure, how hydrogen an residual stresses drive failures, an how fi apply preheat, PWHT, consumable selection, joint design, machining controls, an testing methods fi prevent defects an extend component life.
Elevify advantages
Develop skills
- Control weld hardness by tuning microstructure to stop cold cracking on shafts.
- Prevent hydrogen cracking through managing preheat, diffusion, and low-hydrogen consumables.
- Reduce weld and turning stresses by optimising joint design, toe finish, and sequencing.
- Plan weld failure analyses by selecting tests, mapping hardness, and reading fracture surfaces.
- Select weld processes and fillers to match AISI 4140 shafts for strength and toughness.
