We are currently developing temper bead procedures to be used in conjunction with the NBIC alternative methods to PWHT. Will I need to have our qualified welders to perform the proficiency demonstration when using these procedures for repairs?
I need to attach some temporary lugs (push-pull) to a section of the vessel that has been heat treated. The lugs will be of P-1 material and attached by 3/8" fillet weld, the shell is P-1 material with a 1" thickness.
I don't see anything in sect. VIII that gives me a out to having to PWHT these...
