This includes requirements for mate- rials, design, fabrication, examination, inspection, and stamping. For the listing below, the Page references the affected area.
Refer to figure QW 1. The minimum temperature for welding shall be specif ed in the WPS. Davenport — Pennsylvania S. The accept- ance standards of QW Qualification in accordance with Section IX is not a guarantee that procedures and performance qualifi- cations will be acceptable to a particular construction code. Where temper bead welding is to be applied to only one side of a joint e.
When essential variables are qualified by one or more PQRs and supplementary essential variables are qualified by other Aeme, the ranges of essential variables established by the former PQRs are only affected by the latter to the extent specified in the applicable supplementary essential variable e.
Rounded indications less than V 32 in. As a minimum, the PQR shall document the essential variables and other aske information identified in Article Vpvc for each process used during welding the test coupon and the results of the required testing.
Pro- duction assembly mockups may be used in lieu of QW When notch toughness is required by 20110 construction code, the supple- mentary essential variables become additional essential variables and a change requires requalification of the procedure. McLaughlin, Vice Chair U. However, other Sections of the Code state the rules under which Section IX requirements are mandatory, in whole or in part, and give additional requirements.
For other metals, the failure strength shall not be less than half of the minimum specified tensile strength of the stud material. The specimen thickness and bend radius are shown in figures QW The footnotes wsme this document are part of this American National Standard.
A peel test specimen at least 6 in. When an immediate retest is made, the welder or welding operator shall make two consecutive test coupons for each position which he has failed, all of which shall pass the test requirements.

Pucek — Wisconsin R. 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. Mraz, Contributing Member D. A welder qualified to weld in accordance with one quali- fied WPS is also qualified to weld in accordance with other qualified WPSs, using the same welding process, within the limits of the essential variables of QW When a procedure has been previously qualified to sat- isfy all requirements other than notch toughness, it is ixx necessary only to prepare an additional test coupon using the same procedure with the same essential variables, but additionally with all of the required supplementary essen- tial variables, with the coupon long enough to 210 the necessary notch- toughness specimens.
For combination qualifications in a single test coupon, the limits for thicknesses of deposited weld metal, and bend and fillet testing are given in QW and shall be consid- ered individually for each welder or welding operator for each welding process or whenever there is a change in an essential variable.
Plate in a horizontal plane with the weld metal deposited asmd above. Guided-bend specimens shall be bent in test jigs that are in substantial accordance with QW If the welder or welding operator has had his qualification with- drawn for specific reasons, the employing organization shall notify all other participating organizations that the welder’s or welding operator’s qualification s has been revoked in accordance with Bpvvc When the welder or the welding operator has had further training or practice, a new test shall be made for each position on which he failed to meet the requirements.
Alternatively, a minimum 6 in. If it is desired to provide tolerances in the WPS for two variables, the first variable with a tolerance shall be set at the midpoint of its tolerance and two test coupons shall be welded with each of the upper and lower extremes of the tolerance for the second variable i. D’Urso, Staff Secretary J. The essential variables listed in table QW In addition, when notch toughness testing is required for procedure qualification, the applicable sup- plementary essential variables for each process shall be recorded.
Bryan — Tennessee M. Jacobs, Contributing Member R. PublicReview — Revisions to invite comments from all interested persons. The performance qualifica- tion tests are intended to determine the ability of welders and welding operators to make sound welds. QW I Criteria — Bend Tests The weld and heat-affected zone of a transverse weld- bend specimen shall be completely within the bent portion of the specimen after testing. Ghosal, Vice Chair B.
Rodriguez, Vice Chair P. Hall, Vice Chair G. Using a magnification of 10X to 20X, the exposed cross sections bovc the weld shall confirm a minimum leak path dimension required by the design b no cracking c complete fusion of the weld deposit into the tube- sheet and tube wall face d complete id of the weld deposit to within!
Alternatively, if adequate material of the original test coupon exists, additional test specimens may be removed as close as practicable to the original specimen location to replace the failed test specimens.

Sullivan, Contributing Member P. Production tests conducted in accordance with the requirements of other Sections may be used to satisfy this requirement.
The approximate location of beads to be deposited relative to the original base metal surface shall be identified, and the applicable parameters shall be used for the layers to be deposited as specified by the WPS. Kraft — Maryland B. Brzuszkiewicz, Staff Secretary R. No more than three essential variables on a WPS may show tolerances.
These rules may also be applied, insofar as they are applicable, to other manual or machine welding processes permitted in other Sections. When joints are to be made between base metals from two different groups, a procedure qualification must be made for the applicable combination of base met- als, even though procedure qualification tests have been made for each of the two base metals welded to itself. The welding operator qualification is limited by the essential variables given in QW for each type of weld.
Weld metal deposited using each set of variables shall be included in the tension, bend, notch toughness, and other mechanical test specimens that are required. Basile, Vice Chair S.
