Welding Pre-Heating / Post-Heating

The purpose of preheating before welding is to minimize the detrimental effects of high temperature and severe thermal gradients occurred at the time of welding.

Our company received welding preheating works from process and petrochemical industries and therefore the requirements and preheating conditions are to be in line with relevant standards such as ASME B31.3, ASME B31.1, etc..
