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.
