Hi and thank you all for your interest in providing a solution to our "dilemma."
The preheat statement was found in a gneric procedure for making any type of
weld repair at my employer. To date there has been alot of research and we have

I agree, but still want to see where something tells the requirement of having
the preheat temperature for a weld repair increased by 150 degrees F.
What about 125 degrees? What about 200 degrees? I know there is also a
metallurgical concern such as hydrogen cracking, HAZ hardness, weld metal...
Thank you for taking time to respond to my inquiry.
I was merely hoping someone might remember which document / which specification / which procedure may / might have an instruction to preheat the area of a weld repair 150 degrees F higher than the preheat requirement as shown on the related WPS...
Good afternoon,
Being new to the job, I reviewed a Quality Control Procedure which mentioned the need for preheating the area of the weld repair 150 degrees F. higher than the normal welding procedure preheat temperature. We have looked in ASME Section IX, Section VIII, Section V, API-8C and...
