Nelson — Colorado W. Sketches, tables, figures, and graphs should be submitted as appropriate. When the welder amse 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.

A PQR is a record of the welding data used to weld a test coupon. The Standards Committee that approved the code or standard was balanced to assure that individuals from competent and concerned interests have had an opportunity to participate.

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 bpvf ser- vice so as to give a reasonably long, safe period of use- fulness.

For combination qualifications in a b;vc test coupon, the limits vpvc 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.


Pucek — Wisconsin R.

This paragraph only applies when the essential variables for the buttering process are different than the essential variables for the process used for subse- quent completion of the joint.

These may differ slightly from other welding documents. In the Edition, rules for temper bead welding were added.

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.

Graham — Oregon R. In addition, when base metals of two different P-Number Group Number combinations are qualified using a single test coupon, that coupon qualifies the welding of those two P-Number Group Numbers to themselves as well as to each other using the variables qualified. Monroe — Oklahoma G. Metals were listed in numerical order by material specification number to aid users in locating the appropriate grouping number.

Welding Procedure Specifications, Procedure Qualifica- tion Records, and WelderlWelding Operator Performance Qualification made in accordance with the requirements of the Editions of Section IX prior toin which all bpc the requirements of the Edition or later Editions are met, may also be used.

This test coupon shall be cut transverse to the length of the weld into ten pieces, each approximately 1 in.

The dimensions of the fusion zone and penetration of each weld of the transverse specimens shall be measured to the nearest hundredth of an ux and recorded.

Park, Vice Chair R. This certification is intended to be the manufacturer’s or contractor’s verifica- tion that bbpvc information in the PQR is a true record of the variables that were used during the welding of the test coupon and that the resulting tensile, bend, or macro as required test results are in compliance with Section IX. Sharp, Staff Secretary R. Refer to figure QW 1. Partial penetration groove welds and fillet welds are considered welding with backing.


There may be exceptions or additional requirements for the processes of QW, QW, and the special processes of QW Each stud five joints shall be tested either by ham- mering over until one-fourth of its length is flat on the test piece or by bending the stud to an angle of at least 15 deg and returning it to its original position using a test jig and an adapter location dimension that are in accordance with figure QW Four side bend test specimens shall be removed from the completed test coupon and tested.

Tests shall be made in accordance with QW These arti- cles deal with the following: The weld is assme allel to the longitudinal axis of the specimen, which is bent so that the root surface becomes the convex side of the bent specimen.

Limits of qualification shall be in accordance with table QW Bryan — Tennessee M. The pipe is rotated during welding. Stewart — Montana R. Stud welds may be made in test coupons oriented in any of the positions as described in QW for plate and QW for pipe excluding QW-
