We have a seam less carbon steel SA-106 pipe spool duly Post weld heat treated.
Due to mis match, we had to cut two circumferencial welds and re done them. We are ready to conduct PWHT again, the question is do we need to re test any property of spool or place a test pipe and check properties again?

Thanks all!!
