Where a combination of welding processes is required to make a weldment, each welder shall be qualified for the particular welding process or processes he will be required to use in production welding. Piatt — Connecticut J. The samples shall be polished, etched, and shall be free from cracks and shall show no incomplete bond or porosity on or adjacent to the bond lines.
Each organization’s representative shall perform a visual examination of each completed test coupon and shall exam- ine each test specimen to determine as,e acceptability. Solovey, Vice Chair D.
Materials covered by these specifications are acceptable for use in items covered by the Code Sections only to the degree indicated in the applicable Section. O’Brien, Staff Secretary J.
The Secretary of the ASME Boiler axme Pressure Vessel Committee or of the appropriate Subcom- mittee shall acknowledge receipt of each properly prepared inquiry and shall provide a written response to the inquirer upon completion of the requested action by the Code Committee.
The action of the Standards Committees becomes effective only after confirmation by letter ballot of the Committees and approval by ASME. For nontubular cross sections, four side-bend specimens shall be prepared from the two remaining coupons adme specified in figure QW Revised QW to provide a space for recording heat input.
All mechanical tests shall meet the requirements pre- scribed in QW or QW, as applicable. A change from one welding process to another welding process is an essen- tial variable and requires requalification. A peel test specimen at least 6 in. Every other welding stud five joints shall be tested either by hammering 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 The inquirer may desire or be asked to attend a meeting ixx the Committee to make a formal presentation or to answer questions from the Committee members with regard to the inquiry.
Qualification shall utilize a test coupon appropriate to the planned production work. These articles also include assignments of P-Numbers and F-Numbers to particular base materials and filler mate- rials.

aasme Only one mockup weld is required to renew a welder’s or welding operator’s qualification when that qualification has expired or been revoked per the requirements of QW Tests as described in QW are used to determine the size, contour, and degree of soundness of fillet welds. It shall consist of a groove weld, a cavity in a plate, bpvv, or other bpvcc geometry. When using the jigs illustrated in figure QW Alter- natively, after visual examination, when the test coupon s are prepared and tested by an independent laboratory, that laboratory’s report may be used as the basis for accepting the test results.
WPS qualified on groove welds shall be applicable for weld repairs to groove and fillet welds and for weld buildup amse the following provisions: Qualification in the horizontal, vertical, and overhead positions shall qualify for all positions.
One of the test specimens shall be fracture tested in accordance with QW and the other macro- examined to the requirements of QW-1 In-process repairs are defined as repairs in which a flaw is mechanically removed and a repair weld is made before welding of a joint is presented for final visual inspection.
In general, notch-toughness requirements are mandatory for all P-No. Doty, Honorary Member D. Revised temper bead welding essential variable QW If there is evidence that xi production welds are not being made in accordance with the procedure specification, the authorized inspector may require that a check be made on the chemical composition of the weld metal.
Additional information can be incorporated into a PQR at a later date bpbc the information is substantiated as having been part of the original qualification condition by lab record or similar data. Bryan — Tennessee M. No more than three essential variables on a WPS may show tolerances.
Refer to figure QW Each WPS may include one or a combination of processes, filler metals, or other variables.
