No we will not do PWHT more than once. Just concerned if the current from welding on butt will affect the recorder that is being used to monitor the PWHT on another Butt on the same line
In my opinion these materials should be rejected if there is no traceability between the actual material and the MTC. There will be no way for you to confirm that the actual material conforms to the material specification to which it was manufactured. Some tests that may have been required by...

My PWHT contractor has stated that this may be a problem. I myself have never heard of this being an issue.
