Post Weld Heat Treatment (PWHT) PWHT Requirements

Post-weld heat treatment or PWHT is a controlled process that involves reheating the metal below its lower critical transformation temperature, following a welding process. The material is then held at the elevated temperature for a predetermined period of time to alleviate residual stresses, increase the strength, increase or decrease the hardness, and reduce the risk of cracking by Heat Treatment Methods for Carbon and Alloy Steel PipeIBR - 1950 Reg. 348Reg. 348.

The temperature of the heating and the length of time at this temperature, or soaking period,

Heat Treatment of Welded Joints - Part 1 - TWI

Normalising This is a heat treatment that is carried out only on ferritic steels. It comprises heating the steel to some 30-50°C above the upper transformation temperature (for a 0.20% carbon steel this would be around 910°C) and cooling in still air. This results in a reduction in grain size and improvements in both strength and toughness.Heat Treatment Solution Treatment Stainless Steel CastingWith the method of solution treatment, stainless steel castings are softened. Generally, stainless steel castings are heated to around 950-1150 °C and kept for a period of time for the purpose of making carbides and various alloy elements to be fully and uniformly dissolved in austenite, and then it is quickly quenched and cooled.Heat Treatment Process of ASTM A53 Line PipeHeat Treatment Process of ASTM A53 Line Pipe.
