PWHT

Post Weld Heat Treatment (PWHT) is a vital process in welding that reduces and redistributes residual stresses in materials caused by welding. The effectiveness depends on material type, temperature, and soaking time. PWHT guidelines suggest 1 hour of soaking at peak temperature for every 25mm of thickness, but specific cases vary. Higher temperatures during PWHT can improve ductility and reduce brittle fracture risk. Al-Nasha offers PWHT using electricity, enhancing structural integrity, and minimizing downtime. These services cover various components and can be applied on-site, ensuring flexibility and efficiency.
