    ASME IX Multiple PQR PWHT Heat Inputs

    Thanks for the comments. Believe me, I wasn't purposely shooting myself in the foot! Normally we do run a coupon with short and long but had an issue with the short and had to qualify separately later. Definitely not ideal but is what it is. Was much more complicated one than the usual qual...

    ASME IX Multiple PQR PWHT Heat Inputs

    I have a WPS supported by 2 PQRs that is going through 3rd party review (impacts required). There is a difference of opinion on the heat input allowed for the WPS. The governing codes are API6A and ASME IX. The production material is 1" thick. I've only posted a minimum amount of information...

    Question re: Travel Speed & AWS D1.1

    Are you talking about Note C on Table 4.5, or item 18 on Table 4.5? Your question is a bit vague. Your allowable range on the WPS will be based on what you recorded during the welding of your qualification test plate. Hopefully you recorded the travel speed for each pass which would give you...

    ASME Section VIII D1 Interpretation UG-84(h)(2) last paragraph

    I was wondering if someone could help with interpretaion to the last paragraph regarding fillet welds. Does this requirement apply to all fillet welds or just to P11 materials? The last sentence of that paragraph seems to indicate that the paragraph is only applicable to P11 materials. I was...

    Troubleshooting Strip Overlay (SAW)

    Not sure if you already do this, but we cut the end of our strip with a 30 degree angle across the width. That way the arc is established gradually across the width instead of trying to arc the entire 60mm width.

    ASME IX - Production Assembly Mockup - Fillet Weld Qualification

    I have qualified some production tooling that the shop wanted made out of sockets and materials that was difficult or impossible to get in plate or ideal shapes for a traditional procedure. Basically I had them weld it up and followed the instructions for qualifying a mock up. Because of...

    PWHT requirement for ASME section IX pipe welding

    Dido on what everyone else said, but additionally I would have a production welder weld a test pipe for each material you have listed in its most common size with the same welding wire and process you plan to use in production. Have a hardness survey done on a cross-section per which ever NACE...

    cwi exam

    Just got my results yesterday and I passed the exam! Whew!

    cwi exam

    I just took mine and I am still waiting on the results. It was a lot tougher than I originally thought, but I feel pretty good about passing. I felt the exam was just as much (or more) about test taking strategy as it was welding content. Keeping my fingers crossed.......

    Procedure Qualification question

    For your plate qualification in the flat, you will be limited to flat only position per your welding procedure. See QW-256.1 and QW405.4. Position is an essential variable. If your welder was qualified for corrosion resistant overlays in the 6G position, he can weld overlays in any position...

    Counting Ferrite/Austenite % in Duplex microstructure

    thanks for the info.....I saw that ASTM E562 references E 1245 for automatic image analysis. I ended up figuring out how to use the Buehler Omnimet software with the metallograph to do this function.....works great, however, a little subjectivity required....beats the hand count method....

    Counting Ferrite/Austenite % in Duplex microstructure

    I am trying to do a % austenite/ferrite count on a weld crossection of 2205. NACE MR0175 requres the count per ASTM E562. I have the standard, but have never used it before. It seems like it would be really difficult to do in the weld considering the microstructure. Has anyone followed the...

    NACE MR 0103 compliance

    You're correct...typo on my part... So used to writing "RP".

    NACE MR 0103 compliance

    If they specified MR0103 and you have carbon steel in the equation, you will need to follow RP0472. Are you working to the latest version - RP0472-2010? You do not have to PWHT carbon steels in either MR0175 or MR0103, however, you do need to demonstrate your materials, welding process and...

    Alloy 625 welding procedure test failure

    I have some data from a few years ago and we were getting 123ksi-125ksi (848 MPa) with ERNiCrMo-3 filler and that was on some thicker plate. Not much higher than the minimum. Its seems like you are very close to passing. Since your tensile specimens will be much thinner than mine, I would...
