Chemical analysis is not mandatory in PQR unless it is mentioned in WPS before PQR Qualification. Whatever the elements mentioned in WPS, it should be done in PQR.

There is no requirement for width.  There is no requirement for the length of a single film. There is a requirement for the minimum length to be radiographic in case of spot RT (read UW-52). Each one welder's job has to be RTed. One spot for each 15 meters of weld has to be RTed. The min length of the spot is 150 mm Στις Πέμ, 19 Μαρ 2020 στις 1:10 μ.μ., ο/η 'anand gupta' via Materials & Welding < materials-welding@googlegroups.com > έγραψε: Dear all Please confirm the width of RT film as per ASME Sec VIII.  Regards  A p gupta  Baroda  Sent from Yahoo Mail on Android -- https://materials-welding.blogspot.com/ https://www.linkedin.com/groups/122787 --- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.

When ASME BPVC Is applicable then: 1. The minimum thickness of hardfacing has to be specified in the WPS The minimum thickness depends on which surface the chemical analysis or hardness test is conducted. You should read the Notes on Fig. QW-462(s) 2. There is no limit to the max thickness that can be used in production 3. The Chemical analysis has to be defined in the WPS. ASME does not impose any ranges/ In ASME it is not mandatory to specify a chemical analysis in the WPS, but if specified it has to be checked. However, the Classification of the filler metal is an essential variable, contrary to the ordinary welding (read QW-404.12) Στις Τρί, 24 Μαρ 2020 στις 6:33 π.μ., ο/η SURESH < qms.pjgpl@gmail.com > έγραψε: Dear Experts Please through your view on below subject 1.What will be the qualification range, when a PQR is made by hardfacing weld(ER CoCr-A) on 1.6mm base to weld 2.

Your TPI is right, read the Code: (d) When a chemical composition is specified in the WPS, chemical analysis specimens shall be removed at locations specified in Figure QW-462.5(b) or Figure QW-462.5(e). The chemical analysis shall be performed in accordance with Figure QW-462.5(a) and shall be within the range specified in the WPS. This chemical analysis is not required when a chemical composition is not specified on the WPS. If you specify the chemical analysis in the WPS then you have to confirm by testing that you achieved what you have specified in the WPS. So read the Code carefully otherwise you shoot on your own legs Στις Κυρ, 29 Μαρ 2020 στις 3:06 μ.μ., ο/η < sathishmech04@gmail.com > έγραψε: Dear Experts Process:PTAW MATERIAL GRADE:P.NO.1,8,5A,15E Hard facing overlay welding 4 to 5mm welded and machined to 1.6mm.

If you are working to ASME no third party witness is required.  Your Authorized Inspector (AI) will definitely have involvement but they are not required to witness WPS involvement.   If you are working to AWS no third party witness is required.   If you are working to ISO 15614, third party witness by a Notified Body (NOBO) is required.   If you are doing structural work for Canada.   CWB witness is required and a retained Canadian Chartered Engineer is typically also required for companies operating outside of Canada.   If you are interested – my experience – hope it helps.   John   From: materials-welding@googlegroups.com [mailto:materials-welding@googlegroups.com] On Behalf Of Prakash Gotimukul Sent: Thursday, March 26, 2020 5:35 AM To: materials-welding Subject: Re: [MW:30663] TPI approval on WPS   For projects in middle east it is almost mandatory that a TPI is used although it is not...
