When it has been determined that the test failure was caused by an essential or supplementary essential variable, a new test coupon may be welded with appropriate changes to the variable s that was determined to cause the test failure. If this length does not meet the examination standards, the welding operator has failed the retest and all of the produc- tion welds made by this welding operator shall be examined completely and repaired by asmr qualified welder or welding operator.

bvpc QW describes etching processes and reagents. In addition, welders and welding operators who pass the required tests for groove welds shall also be qualified to make fillet welds in all thicknesses and pipe diameters of asms size within the limits of the welding variables of QW or QW, as applicable.

The equipment used for stud welding shall be completely auto- matic except for manual starting. Welders and welding operators who pass the required tests for groove welds in the test positions of table QW The radiographic examination in QW for welders and in QW for welding opera- tors shall meet the requirements of Article 2, Section V, except as follows: The Committee recognizes that tools and techniques used for design and analysis change as technology prog- resses and expects engineers to use good judgment in the application of these tools.

Also, removed the words “visual observation” and replaced them with “changes” since there are other means, e. These variables listed for each welding process in tables QW through QW bpvd subdivided into essential variables, supple- mentary essential variables, and nonessential variables QW The specimens shall be tested in amse with QW, except for the following: For test coupons made on pipe in position 5G or 6G of figure QW San March i, Contributing Member B.

The approximate location of beads bvc 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. Each WPS may include one or a combination of processes, filler metals, or other variables.

The assignments do not imply that base metals may be indiscriminately substituted for a base metal which was used in the qualification test without consideration of the compatibility from the standpoint of metallurgical proper- ties, postweld heat treatment, design, mechanical proper- ties, and service requirements.

If specific qualification test requirements are not specified by the applicable Code Section, welders and welding operators shall be qualified with one of the follow- ing methods: 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.

Chockie, Honorary Member C. Oyamada, Contributing Member C.

The Boiler and Pressure Vessel Committee in the formu- lation of its rules and in the establishment of maximum design and operating pressures considers materials, con- struction, method of fabrication, inspection, and safety devices.

Designation of nominal chemical composition may also be by reference to the AWS classifi- cation except for the “G” suffix classification, the manufac- turer’s trade designation, or other established procurement documents.

Norton, Vice Chair G. Mechanical testing of the completed weldment shall be in accordance with QW When essential variables are qualified by one or more PQRs and supplementary essential variables are qualified by other PQRs, 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.

DeMichael, Vice Chair C. The weld is par- allel to the longitudinal axis of the specimen, which is bent so that the root surface becomes the convex side of the bent specimen.

C Turczynski B, W. It shall consist of a groove weld, a cavity in a plate, overlay, or other suitable geometry.

In addition, welders and welding operators who pass 0210 required tests for groove welds shall also be qualified to make fillet welds in all thicknesses and pipe diameters of any size within the limits of the welding variables of QW or QW, as applicable.

Where such welding or brazing factors are determined by the Manufacturer to affect weld or braze properties, the Manufacturer shall address those welding or brazing factors to ensure that the required properties are achieved in the production weld- ment or brazement.

Sharp, Staff Secretary R. Six tension shear spec- imens and eight macro specimens are required to qualify each procedure.

I us, Delegate M. Guided-bend specimens are of five types, depending on whether the axis of the weld is transverse or parallel to the longitudinal axis of the speci- men, and which surface side, face, or root is on the convex outer side of bent specimen.

More than one procedure qualification may be required to qualify for some dissimilar thickness combinations. For pipes NPS 20100 DN25 and smaller, and nontubular cross sections, two full-section tensile specimens shall be prepared in accordance with figure QW Looking forward, a number of CSEF alloys strength is enhanced by the creation of a precise condition are already in use in Code Cases and drawing near to of microstructure, specifically martensite or bainite, which incorporation.

Welders and welding operators who will apply the cladding portion of a weld between clad materials shall be qualified in accordance with QW No changes were required.

Burpee — Maine C. Groove weld test specimens shall be removed in a manner similar to that shown in bpvvc QW It is divided into two parts: Those cross sections shall be smoothed and etched with a suitable etchant see QW to give a clear definition of the weld metal and heat affected zone.

Those cross sections shall be smoothed and etched 200 a suitable etchant see QW to give a clear definition of the weld metal and heat affected zone.
