These may differ slightly from other welding documents. Testing and acceptance criteria shall be in accor- dance with QW Rieger — Manitoba, Canada A.
The test coupon shall then be welded around the edges, sealing the space between the members as shown in figure QW The welds shall show complete fusion and no evidence of burn- ing through the tube wall, and shall be free from cracking or porosity.
Pipe with its axis vertical so that the weld is deposited on the upper side of the horizontal surface and against the vertical surface. Nonpressure-retaining fillet welds, as defined in other Sections of the Code, may as an alternate be qualified with fillet welds only.
He is qualified only within the limits for positions specified in QW 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.
Norton, Vice Chair G. A machine shall be requalified whenever it is rebuilt, moved to a new location requiring bpvx change in power supply, when the power supply is changed, or any other significant change is made to the equipment. In general, notch-toughness requirements are mandatory for all P-No.

Nisbett, Corresponding Member G. The purpose for qualification of a WPS is to determine that the weldment proposed for construction is capable of providing the required properties for its intended applica- tion. 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.
Half of the strips from each pipe specimen shall then be prepared as root bend specimens and the remaining strips shall be prepared as face bend specimens in accordance with QW Nonpressure-retaining fillet welds, as defined in other Sections of the Code, may as an alternate be qualified with fillet welds only. The acceptance criteria for welders or welding operators who qualify on production welds by radiography as permitted in QW Cantrell — Nebraska D.
Ryan — Illinois T. The reader is advised to take these pbvc into consideration when using this Section. This limitation applies to fillet welds as well as to ixx welds.
The specimens shall be tested in accordance with QW Hilton — Virginia K. When notch toughness is required by the construction code, the supple- mentary essential variables become additional essential variables and a change requires requalification of the procedure.
A single WPS may cover several essential variable changes as long as a supporting PQR exists for each essential and, when required, supple- mentary essential variable [e. Examination, testing, and acceptance criteria shall be in accordance with QW Welding procedure qualification establishes the prop- erties of the weldment, not the skill of the welder or welding operator.
The drop weight test specimen, the crack starter location, and the orientation shall be as given in the Section requiring such tests. Ghosal, Vice Chair B. The WPS shall limit the depth of the groove, which will receive the corrosion-resistant overlay in order to ensure develop- ment of the full strength of the underlying weld in the base metal.
The revisions are identified with the designation 10 in the margin and, as described in the Foreword, become mandatory 6 months after the publication date of the Edition. As such, this is an active document subject to constant review, interpretation, and improvement to recognize new developments and research data.
Birdsall, Contributing Member M. Handy — Kentucky J. Everett — Georgia C. In order to be acceptable, each specimen shall exhibit complete fusion of the weld metal with the base metal and freedom from cracks.
When the test coupon s is radiographically examined QW The minimum pass length shall be 4 in. These paragraphs require that each manufacturer or con- tractor an assembler or an installer is to be included within this premise shall be responsible for conducting tests to qualify the performance of welders and welding operators in accordance with qualified Welding Procedure Specifica- tions, which his organization employs in the construction of weldments built in accordance with the Code.
The PQR is a record of variables recorded during the welding of the test coupons. The performance qualification articles have numerous paragraphs describing general applicable variables for all processes.
