    UW-2(c) ERW Question

    When the pipe manufacturer states in their MTR saying that the pipe is welded, then it means the welding is by HFI: this process is automatic and no filler metal is used (as required by SA-312).

    UW-2(c) ERW Question

    Afox88, I try to show you some points: 1. SA-312, par 1.1 says "straight-seam welded". 2. SA-312 par 6.1.3 says "welded pipe shall be made using an automatic welding process with no addition of filler metal" 3. UW-2(c)(2) says "the ERW weld shall completed using high frequency welding...

    AWS D1.1 4.13.4 T , Y, or K connections.

    Marcre, IMO you need to make test assembly as per Fig 4.27 and tested acc to Table 4.2, PLUS 3 additional mock-ups acc to 4.13.4.1(2)(a), (b), and (c) and one macroetch test section for each. Regards, AR

    X65 to X52

    Your PQR is using unlisted material (X65), thus according to Table 4.8 (at the bottom of the table) the allowed combination for WPS is "only the specific combination of steels listed in the PQR". So, to weld X65 to X52 you need a new PQR. Regards, AR

    Section IX PQR / WPS question

    Solinar, How to read the essential variable? Essential variable is applied to WPS compared to PQR, not the other way around. So in your case: you may apply preheat for your WPS. However, when you put preheat on your WPS then the welder shall follow it. If you need to weld with preheat less...

    PED directive. Impact test on PQR

    You can use ISO 15614-8 for welding procedure qualification of tube-to-tubesheet. The testing required: VT, PT, RT, Macro, Hardness, and push-out/pull-out (when required).

    Weld procedure qualification test positions.

    If you use 3G, 5G or 6G with uphill progression in your qualification, it qualifies all positions. Regards AR

    Access fittings are Branches under API 1104?

    According to App B of API 1104, for in-service welding (B.2) procedure qualification for fillet weld in Sect. 5 should be applied. Also specified in B.2.3 "The requirements in 5.7 for branch and sleeve welds are appropriate for in-service welding". (Note: 5.7 specify qualification for fillet...

    ASME Section IX LBW and Qualified Thickness for Groove Weld

    Sorry....wrong placed smiley.

    ASME Section IX LBW and Qualified Thickness for Groove Weld

    [smile]Ryan, As your weld is with backing, then "Where the measurement of penetration cannot be made" applies. Thus the limit is 10% thicker. Regards, AR

    ASME Sec. IX Small diameter Procedure Qualification

    You can check Fig. QW-462.3(a) --> see note (b)

    Qualification of Dissimilar Base Metal Thickness with Impacts

    Interpretation: IX-04-11 -- in question 3: when the material are from different P-numbers, then the answer is "No". Thus, in your case : as you have same P-No, then your qualified thk range is 0.120" to 0.75" Regards

    ASME Section IX 407.1 interpretation

    Agree with DD. To make it short: QW-407.6 = QW-407.1 + increase 25% time or more Regards

    Tests of welds Tube-fin, to qualify Procedure ASME IX and EN

    Yes. 2 macros for EN (EN 15613 refers to EN 15614) As for using macros ASME to qualify EN? I think it's not possible. EN different with ASME in term of: sample position (EN 15614), procedure (EN 1321), and acceptance criteria (EN 5817).

    QW 407.2 ASME IX 2013 80% From Production

    As you have PQR with 2 hrs 30 min (150 min), then you can go for WPS until 3 hrs 7.5 min (187.5 min). This equals to 162.5 mm.

    AWS-CWI part B question

    No. It's the weld size
  19. aburafdi

    AWS-CWI part B question

    No.1: Don't mixed up between fillet weld size vs width of weld face No.2: See the tolerance at the top-right of the table --> see the "As fitup" column. R for root opening and alpha for groove angle. Hope this help.

    For WPS, use only Table 4.1 Table 4.10 is for welder / welding operator.
