We are use to test (After re-beveling or cutting) before welding. The reason what I know, you may have some acceptable indication before cutting in that location. That indication may become open to surface. Ref. Below Procedure: This Procedure describes the Operations which will be used to carry-out repairs to damaged bevel ends on materials supplied for the Slug Catcher Works associated with the Offshore Gas Gathering System (OGGS) Project. The methods described in this Document are based upon the requirements of the Specifications and proven methods of achieving the required results. It must be appreciated, however, that these methods may be subject to revision or modification depending upon conditions and circumstances actually encountered. Bevel End Repairs Repairs to damaged bevels will be carried-out as detailed below: i) Minor damage to bevels will be repaired by grinding and/or filing. After affecting such a repair, the bevel will be checked visually by the QA/QC Representative. ii) Major damage to pipe ends, which renders the end preparation unfit for production welding, will be repaired by initial grinding, followed by repair welding in accordance with the attached approved WPS (WPS P -1027a, Rev. 0). The welded repair area will be redressed by grinding. After final grinding, the repaired bevel shall be checked visually and by Magnetic Particle Inspection (MPI) in accordance with the approved procedure by the QA/QC Representative for this operation. The results of the MPI shall be recorded on Form QR-035. iii) Contractor may also opt to utilize a purpose-built End Facing Machine appropriate for bevel repairs on straight lengths of pipe. Once the Machine has 'faced' the desired bevel, the new bevel shall be checked visually and by Magnetic Particle Inspection (MPI) by the QA/QC Representative in accordance with the approved procedure for this operation, and the results recorded on Form QR-035.
