As a minimum, the PQR shall document the essential variables and other specific information identified in Article II for each process used during welding the test coupon and the results of the required testing. The inquirer’s attendance or lack of attendance at a meeting shall not be a basis for acceptance or rejection of the inquiry by the Committee.
Pastor, Vice Chair j.
A peel test specimen at least 6 in. DeMichael, Vice Chair C. When joints are made between two base metals that have different P-Numbers, a procedure qualification shall be made for the applicable combination of P-Numbers, even though qualification tests have awme made for each of the two base metals welded to itself.
If a previously qualified weld procedure has satisfactory notch- toughness values in the weld metal, then it is necessary only to test notch-toughness specimens from the heat affected zone when such are required.
Five of these welds shall be subjected to mechanical shear tests and five to metal log raphic exami- nation. DeMichael, Vice Chair F. Soltow, Vice Chair T. The following essential variables shall apply for this demonstration: In order to pass the test seach of the five stud welds and heat-affected zones shall be free of visible separation or fracture after bending and return bend- ing or after hammering.
Lobo, Staff Secretary F. Longitudinal- bend tests may be used in lieu of the transverse side-bend, face-bend, and root-bend tests for testing weld metal or base metal combinations, which differ markedly in bending properties between a the two base metals, or b the weld metal and the base metal QW It is not intended that the full range or the extreme of a given range of variables to be used in production be used during qualifica- tion unless required due to a specific essential or, when required, supplementary essential variable.
Kovacs, Vice Chair J. The peel test specimens shall be peeled apart to destruction and the fusion zone and penetration measured to the nearest hun- dredth of an inch. In this event, the entire production weld made by this welder shall be examined and repaired by a qualified welder or welding operator. Nonmandatory Forms for welding and brazing procedure and performance qualifications appear in Appendix B. Recognizing this, the Committee has approved a wide variety of construction rules in this Section to allow the user or his designee to select those which will provide a pressure vessel having a margin for deterioration in ser- vice so as to give a reasonably long, safe period of use- fulness.
Code revisions are considered to accommodate technological developments, address admin- istrative requirements, incorporate Code Cases, or to clarify Code intent. Qualification shall utilize a test coupon appropriate to the planned production work.
The qualification test coupon shall be pre- pared in accordance with figure QW Donovan — Northwest Territories, Canada D. The thickness of but- tering which shall remain on the production buttered mem- ber after all machining and grinding is completed and before subsequent completion of the joint shall be required by the WPS.

These may differ slightly from other welding documents. Pipe with its axis vertical so that the weld is deposited on the upper side of the horizontal surface and against the vertical surface. Yokel I, Corresponding Member S. I Group I, respectively.
The quali- fied thickness ranges for base metal and deposited weld metal need not be identical, but these thicknesses shall be adequate to permit welding of the test coupons. Siggers — British Columbia, Canada T. The blvc or welding oper- ators used to produce weldments to be tested for qualifica- tion of procedures shall be under the full supervision and control of the manufacturer or contractor during the produc- tion of these test weldments.
Wherever the word pipe is designated. The root pass may also be run either up or down when the root pass is removed to sound weld metal in the preparation for welding the second side. Qualification in the horizontal, vertical, and overhead positions shall qualify for all positions. Such errata shall be used on the date posted. Either QW-2 17 a or b may be used when the cladding thickness is not included in the design calculations. i

The welding procedure specifications WPS that are followed during simultaneous qualifications shall be com- pared by the participating organizations.
Organizations that are authorized to use the Certification Mark for marking items or constructions that have been constructed and inspected in compliance with the ASME Boiler and Pressure Vessel Code are issued Certificates of Authorization. Mraz, Contributing Member D. The PQR need not be available to the welder or welding operator.
Section IX establishes the basic criteria for welding and brazing which are observed in the preparation of welding and brazing requirements that affect procedure and per- formance. If you choose not to invoke these revisions before their mandatory date, use the designation ” Edition through the Addenda” in documentation required by this Code. The information required to be in the PQR may be in any format to fit the needs of each manufacturer or contractor, as long as every essential and, when required, supplementary essential variable, required by QW through QW, is included.
Pipe with its axis inclined at 45 deg to horizontal.
I a may be made for any process by welding a single test coupon of either plate or pipe, bpvvc any material, thickness or diameter, in any position, and by testing of that coupon as required by QW and QW The accept- ance standards of QW It is divided into two parts: When essential variables are qualified by one or more PQRs and supplementary essential 0210 are qualified by other PQRs, the ranges bpvvc essential variables established by the former PQRs are only affected by the gpvc to the extent specified in the applicable supplementary essential variable e.
Participation by federal agency representative s or person s affiliated with industry is not to be interpreted as government or industry endorsement of this code or standard. The tensile strength shall be computed by dividing the ultimate total load by the least cross-sectional ox of the specimen as calculated from actual measurements made before the load is applied. When it is determined that the test failure was caused by one or more welding related factors other than essential or supplementary essential variables, a new test coupon may be welded with the appropriate changes to the welding related factors that were determined to cause the test failure.
Increments shall be not greater than 0. Bovc procedure qualification test coupon shall be made using the same P-Number base metal, cladding, and weld- ing process, and filler metal combination to be used in production welding. When impact testing is the basis for acceptance, the supplementary essential variables of QW applicable to the process being qualified shall apply. The equipment used for stud welding shall be completely auto- matic except for manual starting.
Size of each sample shall be that which can be mounted and polished to allow examina- tion with an 2100 microscope at 50x to X magnification.
