(EC234/85; 795/24) PREPARATION OF TEST 8.05 Materials (1) The base material, the filler metal and the technique shall comply with the procedure specification. The dimensions of the test material and the length of the weld shall be sufficient to provide the required test specimens. Pipe (2) A minimum nominal diameter of 127 mm and a wall thickness of 9.5 mm is recommended for pipe used as base material, although larger diameter pipe may be used and will satisfy the procedure requirements for all sizes. A smaller size pipe may be used, such as job-size pipe, but in such cases the procedure shall be qualified for that thickness only. Marking (3) Every test shall be witnessed by an inspector who shall mark each coupon on the face side to denote the test position. Test specimens (4) Test specimens shall be welded from one side only and metal or non-combustible backing strip shall not be used, except when required in special cases. (EC234/85; 795/24) 8.06 Purpose of tests (1) The welding tests are intended to determine the ability of welders and welding operators to make sound welds. Termination (2) The certification test may be terminated at any stage of the testing procedure whenever it becomes apparent to the inspector conducting the tests that the welder or welding operator does not have the required skill to produce satisfactory results. Records (3) Each manufacturer shall maintain a record of the procedures, including the essential variables under which welders are examined, and the results of the examinations. Re-examination (4) Where a welder fails a certification test in one position only, that welder may undergo a retest in that position consisting of two separate welds, both of which must pass the test. Failing this retest, that welder may undergo a further certification test after having had additional training or experience satisfactory to the chief inspector. Idem (5) Where a welder fails a certification test in more than one position, that welder shall be required to have additional training or experience before being eligible to undergo a further certification test. c t Current to: September 7, 2024 Page 35 PART VIII - WELDING OF PRESSURE SYSTEMS Section 8.07 Boilers and Pressure Vessels Act Regulations Grinding (6) Weld test specimens are to be machine or flame cut to coupons 38 mm wide and all excess weld material, including backing strip, if used, must be ground off by the welder. Coupons shall not be ground so as to reduce their thickness at the weld below the thickness of the parent metal. Guided bend tests (7) Guided bend tests which show any cracks, openings or other defects in the weld or heat- affected zone on the convex surface and exceeding 3 mm measured in any direction, shall be considered as having failed, except cracks occurring on the corners of the specimen shall not be considered unless there is definite evidence that they result from lack of fusion, slag inclusions or other internal discontinuities. Special materials qualifications (8) A welder must hold a valid certificate (P-1) (F-3) or (P-1) (F-4), issued under these regulations, a welding certificate issued pursuant to section 8.04 for a special material, or a journeyman’s certificate acceptable to the chief inspector before the welder can be considered for testing in a special material or process. Waiver of certain requirements (9) The Chief Inspector may waive the requirement for a fillet weld test for a welder who has successfully passed the tests required for a groove weld. Certificate (10) A welder’s certificate shall show the process, positions, thickness of plate material and symbol under which the holder of the certificate may weld. Duration (11) A welder’s certificate is valid for a period of twelve months from the date of issue or for a longer period if approved by the Chief Inspector provided that a retest may be required at any time if a welder is suspected of losing his proficiency. Waiver of annual test (12) Where a contractor can produce satisfactory radiographic evidence of the continued ability of a welder to do approved welding or proof of welding continuity acceptable to the chief inspector, the annual retest may be waived at the discretion of the chief inspector. Transfer of certificate (13) When an employer requests a transfer of a certificate, that employer shall return it to the chief inspector giving the procedure number of the work about to be assigned to the welder and, if the chief inspector is satisfied that the procedure is similar, the chief inspector may without further test and on payment of the fee, issue to the welder a new certificate which shall bear the same expiry date as the original certificate.

If possible, welding shall be applied from both sides of the plate, or a backing strip or ring may be used to ensure complete penetration. Manually applied welds shall have a convex surface on both sides if applied on both sides of the plates being joined, or on one side if welding is applied from one side only. Valleys and undercutting at edges of welded joints shall not be permitted. The reinforcement may be chipped, ground or machined off flush with the base metal if so desired, after the welding has been completed. (EC234/85) 8.15 Thermal stress-relieving In repairing carbon or low alloy steels, when required by these regulations and considered necessary by an inspector, thermal stress-relieving shall be applied to the completed work in accordance with the requirements of the applicable ASME Code section. Thermal stress- relieving of austenitic steels should not be attempted except in accordance with the recommendations of the manufacturer of the materials or the requirements of the applicable ASME Code. In lieu of thermal stress-relieving of carbon steels, peening or other methods acceptable to an inspector may be employed. (EC234/85; 795/24) 8.16 Repair of defective welds In making a repair to a weld that has failed in service, the defective weld shall be removed by chipping, grinding or gouging until sound metal is reached on all sides. The resulting groove shall be filled as required by the applicable welding procedure. (EC234/85) PERMISSIBLE WELDED REPAIRS CRACKS 8.17 Repair of cracks Before making repairs, care should be taken to investigate the cause of cracks. Where circumstances indicate that welding the crack is likely to result in recurrence, consideration should be given to cutting out the cracked area and installing a patch. Cracks in unstayed shells, drums or headers of boilers or pressure vessels may be repaired by welding provided the cracks do not extend between riveted holes in a longitudinal seam or parallel to the longitudinal riveted seam within 20 mm measured from the nearest caulking edge. The total length of any one such crack shall not exceed 45 mm. Cracks of greater length may be welded, provided the complete repair is radiographed and stress-relieved in compliance with section 8.15. (EC234/85) 8.18 Unstayed surfaces Cracks of any length in unstayed surfaces may be welded provided the welds are thermally stress-relieved in accordance with section 8.15.

(EC234/85) 8.21 Idem Corroded areas around manhole or handhole openings in either stayed or unstayed plates, may be built up by fusion welding provided the average loss of thickness does not exceed fifty percentum of the original plate thickness and provided further that the area to be so repaired does not exceed more than 23 mm from the edge of the hole. (EC234/85) 8.22 Idem Corroded areas in unstayed shells, drums or headers may be built up by fusion welding provided that, in the judgment of an inspector, the strength of the structure has not been impaired. (EC234/85) 8.23 Seal welding Edges of butt straps or plate laps and nozzles or of connections attached by riveting may be restored to original dimensions by welding. Seal welding shall not be used except with the approval of an inspector and in no case where cracks are present in riveted areas. (EC234/85) 8.24 Idem The ends of tubes in fire-tube boilers may be seal welded provided they have not been reduced more than ten per cent in thickness and the requirements of Paragraph PFT-12.2 of Section I of the ASME Boiler and Pressure Vessel Code are satisfied.

Subject to compliance with this requirement, no limit is placed on dimensions or location of such patches nor on the thickness of the material. When the longest dimension of a patch does not exceed sixteen times the plate thickness or a maximum or 200 mm, radiography and stress- relieving are not required. (EC234/85; 795/24) 8.28 New sections Flush or butt-welded patches of new sections may be applied to stayed plates without limitation of size or plate thickness.
