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 amse for the second variable i. If variables are not monitored during welding, they shall not be recorded. San March i, Contributing Member B.
Five mockup welds are required to qualify each welder or welding operator. Essential variables for performance qualification are referenced in QW for each specific welding process. Erler, Contributing Member T. Plate in a horizontal plane with the weld metal deposited from above. Donovan — Northwest Territories, Canada D.
Article V provides the requirements and limitations that govern the use of these documents.

Engineering judgments must be consistent with Code philosophy and such judgments must never be used to overrule mandatory requirements or specific prohibitions of the Code.
Tension tests as described in QW are used to determine the ultimate strength of groove- weld joints. Pipe with its axis vertical so that the weld is deposited on the underside of the horizontal surface and against the vertical surface.
Proposed revisions to 20110 Code approved by the Committee are submitted to the American National Standards Institute and published at http: The coupon shall be pressurized hydrostatic ally until failure occurs. 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 Automated vertical gas metal-arc welding for vertical position only.
Essential variables are those in which a change, as described in the specific vari- ables, is considered to affect the mechanical properties of the weldment, and shall require requaiification of the WPS.
QW Fracture Tests The stem of the 4 in. This test coupon shall be cut transverse to the length of the weld into ten pieces, each approximately 1 in. Owens — Louisiana R.
Refer to figure QW The remaining five welded stud joints shall be tested in torque using a torque testing arrangement that is substan- tially in accordance with figure QW QW Combination of Welding Processes Each welder or welding operator shall be qualified within the limits given in QW for the specific welding pro- cesses he will be required to use in production welding.
C Sallash, Secretary M. 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 22010 change in an essential variable. The Committee’s function is to bvpc rules of safety, relating only to pressure integrity, governing the construc- tion 1 of boilers, pressure vessels, transport tanks and nuclear components, and inservice inspection for pressure integrity of nuclear components and transport tanks, and to interpret these rules when questions arise regarding their intent.
If a production weld is selected for welder performance qualification and it does not meet the examination stan- dards, the welder has failed the test. Such conditions are referred to in this Section as welding “variables. A pipe nipple shall be welded or brazed to the outer member at the hole. The depth of preparation shall be such that at least two layers of weld metal are deposited, one of which may be the surface temper bead layer and deep enough to remove the required bpvv specimens.
There may be exceptions or additional requirements for the processes of QW, QW, and the special processes of QW The test method, extent of tests, and acceptance criteria of the other Sections and QW Brusewitz, Contributing Amse J.
Each part is then divided into articles. Monroe — Oklahoma S. Specify one of the following: QW and QB list additional essential variables which are applicable for specific processes.

Accordingly, it is not intended that this Section be used as a design handbook; rather, engineering judgment must be employed in the selection of those sets of Code rules suitable to any specific service or need.
The Interpretations for each individual Section will be pub- lished separately and will be included as part of asmee update service to that Section. L The tension shear specimens shall conform to the dimensions indicated in the table of figure QW Demonstration of density and image quality requirements on production or technique radiographs shall be considered satisfactory evidence of compliance with Article 2 of Section V b final acceptance of radiographs shall be based on the ability to see the prescribed image and the specified hole of a as,e image quality indicator IQI or the designated wire of assme wire-type IQI.
The American Society of Mechanical Engineers does not “approve,” “certify,” “rate,” or “endorse” any item, construction, or activity and there shall be no statements or implications that might so indicate. The extent of testing i. This code does not address other safety issues relat- ing to the construction of asmme, pressure vessels, transport tanks and nuclear components, and the inservice inspection of nuclear components and transport tanks.
More than one set of impact test specimens shall be removed and tested when weld metal and heat-affected zone material from each process or set of variables cannot be included in a single set of test specimens. Acceptance criteria for the notch- toughness tests are as established in the other Sections of the Code.
These forms are provided for the aid of those who do not wish to design their own forms. When the qualification coupon has failed the visual examination of QW Additional sketches or information may be attached or wsme to record the required variables. The remaining participating organizations shall determine that the welder or welding operator can perform satisfactory 0210 in accor- dance with this Section.
Welders and welding operators who pass the required tests for fillet welds in the test positions of table QW
