Based on the ASME impact test requirement, you need to make assessment to see that either your pressure vessel is exempted from impact testing, or you need to carry out the test. There are 4 steps for impact test exemption assessment. I e i need to carry one impact test on for the base metal range T/2 to T+ 6. Example : for 5 mm sample (impact test coupon) :2.5 to 10 mm qualify. for 10 mm sample 5 to 20 mm .S = Supplementary Essential Variables must be indicated on the WPS and Recorded on the PQR when Impact Testing is required. Changes to these variables when Impact testing is .Normally you need to conduct two set of impact testing, one set in weld metal and one set in heat affected zone.

I have one PQR 9 mm thick, with impact test. The range qualification of qualified WPS with Impact test is 9 mm to 16 mm according QW 403.6 . My question is; What's the thick range qualification qualified by this PQR without impact test, where it's mention in ASME sect IX ? .The rules for austenitic stainless steels in this situation are summarized below. For MDMT below –320F (-196C) impact tests are REQUIRED of all raw material, weld procedure qualifications for both the weld and heat affected zone for each type of weld process, and production weld test specimens (weld and heat affected zone) for each type of weld process.
Specimens for doing mechanical testing (like bend test, impact test etc.) are carved out from the test coupon through machining. These specimens are then subjected to testing in a Laboratory. . What is a Procedure Qualification Record (PQR)? In simple terms, a PQR is a record of the events that happened during the Procedure Qualification .

Procedure Qualification Record (PQR) PQR's are not required if Standard Welding Procedures are used, see below for details. This document contains details of the welding test, it must include details of all the parameters listed as variables in tables QW250 to QW265 for each process involved and all the destructive test results. I need to produce a PQR that requires impact testing, per ASME VIII Div. 1. Is it required that the material I use for the procedure qualification be impact tested? Material used in production would be impact tested, but I am wondering if my PQR material also requires it (of course, the weld/HAZ will need tested). I'm currently looking at UG-84(d).

Reasons such as off-topic, duplicates . Dear Sir On your second input- We may "upgrade" existing 1G.2G.3G,4G PQRs( originally without impact testing- qualified following Table 4.5) by qualifying 3G PQR with Impact Testing. Then just have to revise the PQRs (Rev 1) and attached impact test results to each PQRs qualified earlier without CVN. Thus now i should have all the 1G,2G,3G,4G PQRs .
