Heat treatment after welding

Home / Heat treatment after welding

Delta Heat Services specializes in performing heat treatments. A heat treatment is especially functional after metal processing such as welding, but also after casting, pre- or post-processing of metal, or as a repair treatment. Ultimately, it ensures that the mechanical properties improve, which is always an advantage. In this text, we will delve deeper into heat treatment after welding. Read on to discover more.

Reasons to choose for a heat treatment after welding


As already mentioned, heat treatment after welding, also known as PWHT, is very useful if the mechanical properties of the metal are damaged. Sometimes you may not be sure if this is the case. A heat treatment after welding will, in any case, improve the mechanical structure. This includes several subcategories. A heat treatment after welding ensures:

  • Increased flexibility of the metal, making it more resistant to cracks or fractures
  • Reduction of stresses in the metal
  • Enhanced corrosion resistance
  • Improved mechanical properties

How does a heat treatment after welding exactly work?


When a metal piece is welded, a high temperature is reached. As it cools down, residual stress often develops, which can be extreme. When a heat treatment after welding is applied, the stress level can be reduced back to a normal level. Ultimately, other problems related to changes in the mechanical structure can also arise during welding. Therefore, a heat treatment after welding always works well and serves as the finishing touch to the entire process. Did you know that a pre-weld heat treatment can also be performed? This also helps to prevent stresses and fractures.
