Pre Heating
Pre Heating Testing Service in Delhi NCR
Preheating is a fundamental practice in welding and metal fabrication that involves raising the temperature of the base material prior to initiating the welding process. By elevating the temperature in the immediate weld zone, preheating effectively reduces the temperature gradient between the welding heat and the surrounding cooler material, helping to mitigate potential cracking, distortion, and residual stresses. This process is especially beneficial when working with materials prone to high thermal contraction rates or when dealing with thick sections. Preheating ensures a more uniform distribution of heat, minimizes the risk of cold cracking, and promotes better fusion between the filler material and the base metal, ultimately contributing to improved weld quality and the overall structural integrity of the welded joint.
