Fig. 1 Heat treatment of welded joints. Solution treatment. Carried out at a high temperature and designed to take into a solution elements and compounds which are then retained in solution by cooling rapidly from the solution treatment temperature. This may be done to reduce the strength of the joint or to improve its corrosion resistance.

In order to ensure the material strength of a part is retained after welding, a process known as Post Weld Heat Treatment (PWHT) is regularly performed. PWHT can be used to reduce residual stresses, as a method of hardness control, or even to enhance material strength.

Several of the codes have a similar thickness limit, at ~32mm, above which PWHT is required. Provision is made in several codes [14,18 20,25] to extend this limit to 38 or 40mm if certain conditions, generally the imposition of a preheat of the order of 93°C (200°F), are met. The notable exceptions are ASME B31.1 and B31.3 , with a thickness limit of 19mm, and EEMUA 158 that specifies a
