I have an issue with an NDT vendor. He is asked to perform MPI per ASTM E1444 Rev.5 on the welds only. He provides me a cert indicating the part passed. A picture is on the cert showing an indication .125" lg. on the material 5" away from the weld. Asking a question on the cert "This is noted for customer to review.".
The area he shows gets machined away, he does not know this. My question is what is base metal? The two materials being welded? Or two pieces of parent metal being welded by the weld area only. Please clarify.
