Product informationAbout Us
Post-weld heat treatment (PWHT) machine to improve the microstructure of the weld and reduce residual stresses generated during the welding process.Our company specializes in PWHT for the steel and metal processing industries, including pressure vessels, pressure pipes, storage tanks, buildings, bridges, offshore platforms, power plants, oil and gas refineries and petrochemical plants.PWHT is usually mandatory due to compliance with welding specifications and specifications for certain materials, including but not limited to carbon steel, stainless steel/high alloy steel and work hardened steel. PWHT requirements may also be present based on the wall thickness of the components that are welded together.

PWHT reduces or redistributes the residual stress introduced by the welding process by heating, soaking and cooling the weldment/machined surface to a controlled temperature. This improves the performance of the weldment/machined surface. Other benefits of PWHT include:

1. Improve the ductility of materials

2. Improve or reduce hardness

3. Reduce the risk of brittle fracture

4. Relieve thermal stress

5. Hardened metal

6. Eliminate diffusible hydrogen (prevent hydrogen from cracking)

7.Improve metallurgical structure

The 50KVA heat treatment unit has been robustly constructed to provide power to electrical resistance heaters at 60 volts, suitable for site and shop working. The output from the unit is split into six individual heating circuits for temperature control. Each output circuit has 8.3KW of power, which is sufficient capacity for 3 standard ceramic pads rated at 2.7 kW and connected in parallel.There are 3 operational methods of heat control; fully-integrated individual programmers, an external programmer for all channels, and individual proportional energy regulators.Sufficient for 3 ceramic heater pads per channel, this mobile unit is suitable for both site or fabrication shop use.
