Facts About National Texas Stress Day

Hidden Stresses in Welded Steel 

When steel components in refineries or power plants are welded, the metal near the joint cools unevenly, which locks in residual stresses high enough to cause cracking even under normal operating loads.

Post-weld heat treatment (PWHT) gently reheats the welded area, typically to about 1,100 to 1,350 °F (roughly 595 to 725 °C) for carbon steels, and holds it there long enough for the internal stresses to relax and the microstructure to stabilize, significantly reducing the risk of in-service failures.  

Why Temperature Control Around Welds Is So Precise

Industrial welds that will see high pressure or temperature cycles are often heated and cooled within very narrow bands, sometimes controlled within just a few degrees, because both underheating and overheating can damage the metal.

If the temperature is too low during stress-relief, residual stresses remain; if it is too high or held too long, the weld and surrounding steel can lose strength or toughness, so engineering codes specify tight temperature ranges and soak times based on alloy type and thickness. 

PWHT Requirements Are Written Into Power Piping Codes

For critical power piping in boilers and turbines, U.S. industry follows standards such as ASME B31.1, which require that certain alloy steels be post-weld heat treated at defined temperatures to be acceptable for service.

For example, some chromium-molybdenum steels used in high-temperature lines must be stress-relieved in the neighborhood of 1,200 to 1,375 °F, with the required hold time increasing as pipe wall thickness increases, so that the entire section reaches and maintains the target temperature.

Heat Treatment Helps Prevent Brittle Fracture in Thick Sections

Thick steel plates and heavy-wall pipes are especially vulnerable to brittle fracture at lower temperatures because welding can create hard, crack-prone heat-affected zones.

Proper PWHT reduces hardness and refines the microstructure, which raises the material’s fracture toughness so that, if a crack does start, it is less likely to run catastrophically through a pressure vessel, header, or high-pressure line.  

Preheating Welds Protects Against Hydrogen Cracking 

Before welding heavy or highly restrained components, technicians often preheat the joint to a specific temperature to slow the cooling rate and let hydrogen escape from the weld metal.

This controlled preheat, followed by correctly applied PWHT where required, is a proven way to reduce hydrogen-induced cracking in pipelines, boiler tubes, and pressure parts that operate in demanding petrochemical and power generation environments.

Not All Welds Are Allowed to Skip Stress Relief

Although some modern steels and joint designs can be exempted from PWHT, engineers cannot simply decide to skip it on their own.

Industry codes and standards set specific criteria, such as material group, wall thickness, and service conditions, that determine when post-weld heat treatment is mandatory, when it may be waived, and when alternative procedures must be qualified, which is why field heat-treatment providers work closely with welding engineers and inspectors.  

Field Heat Treatment Turned Into a Specialized Service Industry

As refineries, chemical plants, and power stations grew more complex after World War II, the need to perform controlled heat treatment on massive, fixed equipment drove the development of dedicated field heat-treatment contractors.

These specialists brought portable resistance or induction heating systems, calibrated thermocouples, and chart recorders to job sites so that large vessels, piping systems, and structural welds could be stress-relieved in place without dismantling, which helped reduce downtime while still meeting stringent code requirements.
