Post Heating Testing Service in Delhi NCR

Post-heating is a critical step in the welding and heat treatment process, conducted after the welding has been completed. It involves applying controlled heat to the welded component, typically at a temperature lower than the original preheating temperature. This process is aimed at refining the microstructure of the welded joint and relieving residual stresses that might have accumulated during the cooling phase of welding. Post-heating allows for the reduction of hydrogen embrittlement, minimizes the potential for cracking, and aids in achieving better metallurgical properties by promoting grain refinement and stress relaxation. By carefully managing the temperature and duration of post-heating, manufacturers can enhance the durability and performance of welded structures, particularly in applications where strength, toughness, and fatigue resistance are vital.
