Question(s) and Reply(ies): Background: A welder/welding operator is required to weld with a process within a six month period, in order to maintain qualification to use that process. A welder/welding operator takes a performance qualification test using a process for which the welder is already qualified (e.g. SMAW), but with different essential variables (e.g. different F-number, progression, etc.). During the performance of the test, the organization responsible for supervising and controlling the test, visually examines the weld and determines that it meets the visual acceptance criteria of QW-194. Subsequently, the test coupon is subjected to volumetric NDE or mechanical testing, and fails to meet the acceptance criteria. Question: May a failed performance qualification test, utilizing a process for which the welder/welding operator is currently qualified, satisfy the requirements of QW-322.1(a) for maintaining continuity?

Question(s) and Reply(ies): Background: ASME Section IX, QW-151.2(d), on Reduced Section Tension Test on Pipe, specifies that “When multiple specimens are necessary, the entire thickness shall be mechanically cut into a minimum number of approximately equal strips of a size that can be tested in the available equipment.” However, substantial cross sectional area is lost while splitting the entire thickness for multiple specimens, resulting into untested area at the mid-thickness. By allowing specimens from adjacent areas, full thickness will get tested. Other international standards allow the same. Question: Is it permissible to take specimens from adjacent locations, one sample representing the outer thickness and the other, the inner side of the thickness, with overlapping areas in the mid-thickness, instead of cutting the entire thickness at one location into multiple strips, for one set of reduced section tension test specimens? Reply: No. Standard Designation:

SC IX; QW-202.3 & QW-407.4 P-No. 10H Thickness Restrictions for Weld Repair and Buildup 08/27/2015 15-1533

Question(s) and Reply(ies): Background: A weld procedure qualification is conducted using a base material under P-No. 10H, with a thickness of 1.5". Essential variable QW407.4 applies and restricts the maximum qualified base metal thickness to 1.65" (1.1 x T) when a solution annealing heat treatment is performed after welding. Paragraph QW-202.3(b) states that, "For other than fillet welds, the thickness range for base metal and deposited weld metal for each welding process shall be in accordance with QW-451, except there need be no upper limit on the base metal thickness provided qualification was made on base metal having a thickness of 1½" (38 mm) or more". QW-451.1 Note 1 states that variable QW-407.4 further restricts the limits in this table. Question (1): May this PQR be used to support weld repair and weld buildup on base metal thickness exceeding 1.65 in.? Reply (1): No.

Question (2): Does the term "weld repair" apply to any repair of a weld after the weld is completed and final heat treatment is performed? Reply (2): Section IX does not define weld repair. Standard Designation:

BPV IX-16-

Question(s) and Reply(ies): Background: Materials approved for use by a Code Case require separate qualification of the WPS for joining the “unassigned” material. The Code Case is subsequently revised multiple times. Some revisions alter the chemical composition or method of manufacture for the subject material, and others have no effect on the defining parameters for the material. After each revision of the Code Case, the WPS is reviewed by the qualifying organization to determine whether it remains valid for continued use.

Question: Under the conditions described in the background, do QW-200.1 (c) or QW-424.1 require annotation of the WPS to reflect the WPS remains qualified for joining the unassigned materials when a Code Case is revised, if requalification of the WPS is not required? Reply: No.

Question(s) and Reply(ies): Background: For welding procedure qualifications using the GTAW process, QW-409.1, is a supplementary essential variable. When the heat input method of QW-409.1(a) is used, the values for current, voltage and travel speed must be used in determining the heat input. Heat input calculations using the specified ranges on the WPS for current, voltage and travel speed may give values that exceed the maximum qualified when the results are maximized (e.g. using highest current and voltage values with slowest travel speed).

Question: Is it acceptable to add a statement to the WPS that “current, voltage and travel speed may be adjusted by the welder within the specified ranges provided the maximum qualified heat input is not exceeded”? Reply: Section IX does not address the method of complying with essential variable limits.

Question(s) and Reply(ies): Background: Company A qualified a WPS joining a P-Number 5A material to itself in accordance with QW-283 by buttering both groove faces using a filler metal that does not conform to an AWS classification but is identified on the PQR by trade name. The buttered ends were postweld heat treated and machined so that the buttered thickness after machining was not less than 3/16 inch. The buttered ends were then welded together using a different filler metal. The required mechanical tests were performed. Company B qualified a WPS to butter and heat treat the weld ends (but not perform the groove weld assembling the buttered parts) by making a groove weld in P-number 5A material using the same process, filler metal, and heat treatment temperature range that was used for buttering by Company A. The required mechanical tests were performed. Question (1): Is it required that the production buttering be made with the same heat of the filler metal that was used for the buttered portion of the procedure qualification test coupon? Reply (1): No. Question (2): Is the company B WPS qualified to butter and heat treat the weld ends of the production parts? Reply (2): Yes,

SC IX; QW-407.2 - PWHT Time range 03/03/2016 15-2692

BPV IX-16-

Question(s) and Reply(ies): Background: The range of qualified base metal thickness for a WPS is determined from Table QW-451.1 based upon the thickness of the PQR test coupon. During WPS qualifications, PWHT is applied to the PQR test coupon, at the holding temperature prescribed for the material, for the minimum holding time required by the construction code for the maximum qualified base metal thickness. As a result, the required holding time for PWHT at the holding temperature may vary considerably in production. The variable description for PWHT under QW-407.2 requires the WPS to be qualified with PWHT applied to the PQR test coupon “… essentially equivalent to that encountered in the fabrication of production welds, including at least 80% of the aggregate times at temperature(s)”.

Question (1): Is a WPS qualified for production welding where PWHT is applied for a holding time that is less than 80% of the holding time recorded on the PQR? Reply (1): Yes.

Question (2): Is a WPS qualified for production welding where PWHT is applied for a holding time longer than 125% (reciprocal of 80%) of the holding time recorded on the PQR? Reply (2): No. Standard Designation:
