Thanks David, much appreciated! Kind Regards Marco

Hello, I have one question related to a WPS for A351 CF8M (basically a cast 316SS version). The PQR was performed with a PWHT (solution annealing and water quenching) to 1075°C (1967°F), with impact test. Given that QW 407.2 refers to QW 407.1, and the P no. of the base metal being 8, the...

Thank you guys.... @ Andre this is the answer which is close to my personal experience. The question now is: is there some "official" references (i.e. a standard) to this definition? Marco

Dear Mumawalde, I suggest you to take a look at EN10204 - Metallic products - Types of inspection documents. Should you need a 3.1 certificate, the doc must reflect property of the material you are purchasing, therefore if reference ASTM indicates chemical analysis and mechanical properties, a...

Dear All, hope the question is not too basic. I have in front of me an inspection and test plan (ITP), on which customer has placed, in his column, a series of H,W,R (to which I am quite used to), and a "M". I know it stands for "Monitoring", but it's not clear to me how I should handle it...

Attilio, you should go through the FAQs which you find on the official site: http://www.standard.no/en/Sectors/Petroleum/NORSOK-Standard-Categories/M-Material/M-6503/ I guess the answers given there are very clear. Ciao Marco

Again, I fully agree. Values are 101-106-99 J on HAZ and 90-89-92 on WM, therefore it's more than reasonable to assume lateral expansion values much higher than 0.38 mm (1.00 mm according my experience as well). I will talk to the lab, or try to convince customer. Will let you know how it...

Thank you Metaljon, I am testing a cast alloy 6Mo (ASTM A351 CK3MCuN). I fully agree with you, the problem is that the submitted WPS/PQR was originarily issued 3 years ago, and I am no more in possess of impact test specimens to be measured. So, I see just 2 solutions: 1) trying to convince...

Dear All, I have lately submitted (for a new Project) a previously qualified WPS+PQR (according to ASME IX). At PQR stage I carried out a certain no. of impact tests, reporting the results as energy absorbed [J]. Now, my accurate customer is rejecting the PQRs because project specification...

Dear All, I have to qualify two welding procedures involving following base materials 1)one WPS for A995 GR 4A (UNASSIGNED) to A182 F51 (P No. 10 H Gr 1) 2)one WPS for A995 GR 4A (UNASSIGNED) to A995 GR 4A (UNASSIGNED) Are both WPS qualified by a PQR in which base materials are A995 GR 4A...

if Nace requirement is applicable, double aging shall be carried out, which means that the condition H1150DBL or H1150M shall be the one applicable MC

Guys, your help has been much appreciated! :)

Eddy, sounds clear to me. I will note the minimum temperature on the PQR; isn't it mandatory to list the same minimum temperature on the supported WPS? Jbeckhou, I don't have a min/max value. The aim of the operation is just to eliminate moisture on the weld just before starting the welding...

Thank you Mr168 this is exactly what I supposed. MC

Dear All, I have one question. Our welder is carrying out a qualification of a new WPS, by welding a cast coupon in duplex 2205 with duplex 2209. The welding activities shall be distributed during 5 days. To reduce to minimum the presence of humidity on the weld, the welder shall lightly...
