Postweld heattreatment (PWHT)
Post-weld stress relief annealing is carried out in our large heat treatment furnace (width 10.3 m, depth 8.5 m and height 5.5 m, Tmax 600 °C).
The instructions of the customer, material manufacturers and the designer are followed in stress relieving. The holding temperature, holding time, and temperature increase and decrease rates in stress relief annealing are determined based on the material and its thickness.
