Hot King Instruments manufactures Post Weld Heat Treatment (PWHT) Furnaces for controlled heating of welded components and fabricated structures after welding.
These furnaces help provide uniform heating and controlled temperature cycles for reducing residual stresses and achieving the required metallurgical properties.
A Post Weld Heat Treatment Furnace is an industrial furnace used to heat welded components under controlled temperature conditions after welding.
PWHT is commonly used for stress relieving and thermal treatment of welded pressure vessels, pipelines, fabricated structures, heavy engineering components, and other welded assemblies.
