Heat Treatment is the heating of steel to relatively high temperature (Ex: 590c-700c) shortly after welding and maintaining that temperature for a specific period of time. The purposes is to reduce internal stresses, caused by welding, quench hardening or by cold working .It also has an advanta-geous effect on the elasticity, ductility and strength of the metal.
Types of Heat Treatment :
- Annealing
- Normalizing
- Preheating
- Post weld heat treatment
- Solution Heat Treatment
