II. WELDING PROCEDURE AND QUALIFICATION EVALUATION BASED ON ASME BOILER AND PRESSURE VESSEL CODE, SECTION IX
WELD PROCEDURE REVIEW
The inspector should have the knowledge and skills required to review a Procedure Qualification Record, a Welding Procedure Specification and a Welder Performance Qualification to be able to determine the following:
a) Determine if procedure and qualification records are in compliance with applicable ASME Boiler and
Pressure Vessel Code and any additional requirements of API- 510
The weld procedure review will include:
• Weld Procedure Specification (WPS)
• Procedure Qualification Record (PQR)
• Welder Performance Qualification (WPQ)
b) Determine if all required essential and non-essential variables have been properly addressed.
(Supplemental essential variables will not be a part of the WPS/PQR)
c) Determine that the number and type of mechanical tests that are listed on PQR are the proper tests, and
whether the results are acceptable.
d) Determine that the welder is qualified to make a production weld according to the WPS
WELD PROCEDURE REVIEW WILL ONLY INCLUDE SMAW, GTAW, GMAW, OR SAW, WITH THE FOLLOWING LIMITATIONS:
a) No more than one process will be included on a single WPS,PQR or WPQ and the WPS to be reviewed
will be supported by a single PQR.
b) Filler metals will be limited to one-per-process for SMAW, GTAW, GMAW, or SAW
c) The PQR will be the supporting PQR for the WPS.
d) The WPQ test coupon is to be welded in accordance with a qualified WPS.
e) Base metals will be limited to P1, P3, P4, P5, and P8.
f) Dissimilar base metal joints, and dissimilar thicknesses of base metals will be excluded.
g) Special weld processes such as corrosion-resistant weld metal overlay, hard-facing overlay, and dissimilar
metal welds with buttering of ferritic member will be excluded.
h) For P1, P3, P4, and P5, for the purpose of the examination the lower transition temperature will be 1330°
F and the upper transformation temperature will be 1600°F.
