We are constructing to B31.3 and have determined what we are going to define as a welding lot. We have a pipe spool in one of our welding lots that has not been fabricated correctly to the drawing. We need to cut out several welds to correct the piping spool. Should the cut out welds be considered when determining our x-ray percentage for the lot? If the welds were being cut out due NDE finding weld defects then the welds would definitely have to be considered. However, these welds are being cut out because of a fitting error and will not be part of the final product. Is the intent of B31.3 to have a lot include all welds including fitting mishaps or just all welds that will be apart of the final product and put into service?
