Pre/Post Weld Heat Treatment

Pre/Post Weld Heat Treatment

Metalok Industries delivers reliable and precisely controlled Pre-Weld Heat Treatment (PWHT) and Post-Weld Heat Treatment (PWHT) services to enhance weld quality and structural integrity across Oil & Gas, Petrochemical, Power, and Industrial projects. Our pre-weld heating processes ensure proper temperature control to reduce thermal stresses, prevent cracking, and achieve optimal metallurgical conditions before welding begins. Using advanced resistance and induction heating systems, we maintain uniform heat distribution, ensuring strong, defect-free welds even in critical and high-pressure applications.

Our Post-Weld Heat Treatment services are designed to relieve residual stresses, refine grain structures, and restore the mechanical properties of welded joints to meet international codes and industry requirements. With certified technicians, precise temperature monitoring, and fully calibrated equipment, we deliver safe, consistent, and compliant heat treatment operations at site or in controlled environments. Metalok Industries ensures accurate temperature cycles, proper soaking times, and complete documentation—supporting enhanced durability, extended service life, and reliable long-term performance of welded components across Saudi Arabia.
