POST WELD HEAT TREATMENT(PWHT) IN QATAR

Post Weld Heat Treatment (PWHT) in Qatar

Aries Marine LLC in Qatar specializes in performing PWHT for the steel and metal fabrication industries including the construction of Pressure vessels, Piping, Storage Tanks, Offshore platforms, Power plants, Oil and Gas refineries, and Petrochemical Industries.

PWHT reduces or redistributes the residual stress introduced by the welding process with a technique that involves heating, soaking and cooling the weldment/machined surface to controlled temperatures. This improves the properties of the weldment/machined surface.

Benefits of PWHT include:

  • Improved ductility of the material
  • Improved or reduced hardness
  • Reduced risk of brittle fracture
  • Relaxed thermal stress
  • Tempered metal
  • Removal of diffusible hydrogen (to prevent hydrogen induced cracking)
  • Improved metallurgical structure

Aries Marine is a flagship brand of Aries group, found in 1998 by Mr. Sohan Roy. Aries Marine LLC in Qatar have a good team of Technicians and Engineers who has adequate skill and expertise in all NDT testing practices.
