Residual Stress Relief via Heat Treatment

Physicochemical Mechanism of Action

Residual stresses arise from rapid cooling during welding or manufacturing. These stresses can strain the metal structure and lead to cracks.

Metallurgical Relevance & Risks in Welding

High residual stresses increase the risk of mechanical loading and can cause cracking or distortion in the metal. Targeted stress relief through heat treatment prevents these issues.

Workshop Practice & Procedures

After welding or manufacturing, the metal is heated to a specific temperature in a controlled annealing process and then cooled slowly. This reduces residual stresses in the metal structure. The exact temperature and cooling duration must be adjusted based on the material and application.
