Pre-Heating and Post Weld Heat Treating(PWHT), Metal Stress Relieving and Bakeouts
Our heat treating process, can relieve stress on your weld by heating it to a predetermined temperature before welding. By pre-heating your metal, it does not react to the stress of the rapid temperature change that occurs during welding. After the weld, the same can occur. By applying post weld heat treating, the metal once again is less likely to react as temperature change is not so rapid, leading to a more successful weld.
Helix Oilfield Field Heat Treating technicians are experts at providing the right amount of heat to complete the job quickly and, above all, safely.
