PWHT TEMPERATURE OF DISSIMILAR MATERIAL

PWHT TEMPERATURE OF DISSIMILAR MATERIAL

PWHT TEMPERATURE OF DISSIMILAR MATERIAL

(OP)
I have to weld SA 592 Gr F material with SA 516 Gr 70 material. The joint requires PWHT.

PWHT Temp of SA 592 Gr F - 540 TO 595 Degree cel.
PWHT temp of SA 516 Gr 70 - minimum 595

Which temperature should we follow?

We can not have 595 exactly as the temperature shall always have tolerance , e.g. + - 10 degree cel.

RE: PWHT TEMPERATURE OF DISSIMILAR MATERIAL

Per asme VIII, Div1 you can increase hold time at lower temps.

RE: PWHT TEMPERATURE OF DISSIMILAR MATERIAL

Generally, the higher PWHT should be followed. Customer specifications will usually dictate otherwise.

The devil is in the details; she also wears prada.

RE: PWHT TEMPERATURE OF DISSIMILAR MATERIAL

DVWE is absolutely correct. But you do not face any issues, 595 qualifies for both.
