    Consumable tradename change (rebranding)

    If the weld filler metal keeps the "Trade Name" as was used under "Organization A" then requalification would NOT be required, however if the filler metal was re-named then I would lean towards re-qualification is required.

    asme b31.3-Austenitic stainless steel impact test requirements- table 323.2.2

    Rajj, First off the 2014 Edition is not applicable until August 27, 2015. If you are planning on welding without filler metal (Autogenously) then 323.2.2(f) will exempt you from Impact testing, however; if filler metal will be added to the weld joint, then Impact testing will be required as...

    Inspection issue

    blaqesmith, if an Alteration/ repair is required on this vessel, you may be able to obtain documentation from the certifying body it's registerd with (i.e. National Board/ Pressure Vessel Directive). In most of the vessels I have dealt with I know there are certain documents that are required to...

    UG-84(h)(3)

    Yes you do have to provide Impact testing. See UCS-66 to explanation, it discusses certain joints (i.e. what part welded to what, etc.). It's not the fact that it takes a partial penetration to make the weldment, it is each component to the other that is evaluated.

    S41008 (410s) P7 PWHT Conditions?

    Already attempted that route. I have a .500" thickness. Thanks

    S41008 (410s) P7 PWHT Conditions?

    I agree with all of your recommendations. The 410NiMo filler metal was actually the one specified, however before getting me involved the use of 410 SMAW was used. And before I require them to start cutting all of the welding out (as I am thinking I need to anyway) I was only wanting to cover...

    S41008 (410s) P7 PWHT Conditions?

    I have a project currently underway which involves .500" SA-240 Type 410s (P7 Gr. 1) and the client is imposing a MDMT/CET of -20°F. We have completed the production impact plates as required by ASME VIII-1 (UHA-51(h)) and according to UHA-32 the PWHT of this material is required to be performed...

    PQR: P.No-1 Gr.1 weld to P.No-1 Gr.2

    The acceptance criteria for Grade 2 does not have to be met as well. The requirement is to meet the minimum tensile for the weaker of the 2 (see QW-153.1(b)).

    WPS Charpy Impact Requirements B31.3

    C2012, The only out/ exemption that you have is that if the material you are welding has a thickness (T) less than .098" then Impact testing would not be required (as shown by Table K323.3.1 note 6).

    Max fillet weld size ASME section IX

    You say QW-452(?), this is for Performance qualifications, not a WPS/ PQR per QW-450? Please review the WPS and ensure that the WPS met the requirements of QW-450, QW-150, QW-160, & QW-194. If you are speaking of the Welder Qualification, if it was on a groove weld, the Welder is qualified for...

    WPS with impact tests and PWHT

    tonnesen, Wow what a "kinda" loaded question. As for your 2nd question.... if you did use a 25mm coupon in qualification and performed PWHT at 2 hours (hypethetically), you would then be qualified (with Impact testing applied)as follows: Minimum thickness: 16mm Maximum thickness: 50mm PWHT time...

    Duplex Casting with unassigned P-number

    metengr, I agree as well, Castings can be tricky beasts to overcome at times. Take for example CA6NM; this material has a mind of it's own! Only due to experience and many, many, trials and errors; I do now as a Company's Senior Welding Engineer actually qualify castings as their own entity due...

    Duplex Casting with unassigned P-number

    The Duplex casting you are referencing is also identified by a UNS # (J92205). In accordance with ASME IX QW-420 (bottom left paragraph starts: "If an unlisted base metal...."). When this is used, and the UNS# is found within another "listed" material then this is and can be shown and welded as...

    Is welder qualification by production welding allowed per ASME IX?

    I agree with Mr168; you have to be very careful doing that. What I made the NDT group do was to actually grade the film to both the Code of Construction (ASME B31.3, B31.1, ASME VIII-1, etc.) as well as include that they graded per ASME IX (QW-191.1.1.2.2). The requirements are clearly stated...

    ASME IX impact testing question

    stanweld is correct; this is a very big mistake people make quite regularly. Your design code dictates this requirement; such as if you are designing to ASME VIII-1 then UCS-66 would be your guide with impact testing being performed in accordance with UG-84.

    Size of Filler Metals (QW-404) ASME IX

    A very incomplete PQR or did you remove information to protect the incompetent?

    QW-405.4 (b)

    ASME IX (QW-405.4 (b)) does not apply with HFO; newweldeng09 look at QW-405.4 (c) for your answer. If you have qualified a PQR in the 5G or 6G position where at least one vertical segment was completed in the uphill progression then "All Positions" are qualified by your PQR. As metengr has...

    USING FCAW PROCESS FOR SS OVERLAY IN A CLAD VESSEL

    One other thing that must be kept in mind when PWHT of any Austenitic stainless is performed..... ferrite content as to limit the effects for Sigma Phase formation. It's best to also perform a Ferrite inspection of the surface prior to PWHT to ensure that the ferrite content is between 3FN -...

    NDT for Reformer Heater Tubes

    Pre Heat Maintenace

    According to QW-256 (Variable table in ASME IX), GTAW does not have any documented variable that apply. For instance with SMAW welding Preheat maintenance is a Non Essential Variable; and it only applies when PWHT is required: Example: SMAW NEV QW-406.2 (per QW-253): "A change in the maintenace...
