    impact test

    Based on the limited information you've provided please look at Table UCS 66 Curve B materials up to 11/16" thick are exempt to +10 F

    316ss & Nickel alloy weld fillers with charpy test

    We work with several manufacturers / vendors that offer that service. Be sure to clearly state the requirements on your PO for the consumables and review the MTR to determine that the reported test results are actual, not typical. Some will state their cert is in accordance with EN 10204 3.1...

    Welded head joint efficiency

    Is this a Sec VIII-1 application? If so and you have a copy of ASME Sec VIII-1, review Non Mandatory APP L. In particular look at Fig L-1.4-2. If other specify.

    Adding Toughness Test (Impact Test) results to existing PQR - ASME IX / ASME Section VIII, Div 1

    ASTM A36 required full killed

    Agree with the above comment. Aluminum is also used in killing steel and we often see Si & Al both reported on an MTR. Of course it's much easier to satisfy a customer that the requirement has been met when the MTR states 'fully killed' or words to that effect. If necessary, your steel...

    Adding Toughness Test (Impact Test) results to existing PQR - ASME IX / ASME Section VIII, Div 1

    However, be aware that the interpretation above is no longer valid as written due to a Code change pertaining to the requirements for impact tests in the HAZ. See Table UG 84.6 and CC 2835. Bottom line is that PQR impact tests on a thin plate as described in the interpretation no longer...

    Impact Testing

    For P1 materials RT requirements are a function of design. One can determine RT requirements per Code by reviewing the vessel calculations. Review UW 11, Table UW 12 and the calcs.

    Welding 2205 , 3/4 " Thickness, GMAW OR FCAW

    I guess I'll be the odd man out here but we've had good success using FCAW on 2205 Duplex. I'm basing that on achieving % Ferrite in the range of 35 - 65. Some procedures run a little tighter. I ran a procedure last fall with ferrite running 49.9 to 59.1, but in my experience most customers...

    Max Heat input in SAW welding.

    If you're manufacturing to an ASME code, and impact testing is required, see Sec IX Table QW-254

    Groove weld gap for re-pad

    We typically weld the trunnion to the shell with whatever weld size is required. Normally it's full pen thru the trunnion wall and a fillet. When that's complete drop the repad over the trunnion and weld that joint. The repad opening needs to be sized to accommodate the previously applied fillet.

    Aluminum to Stainless Threaded Connections for Cryogenic Service

    Are there any concerns over using threaded connections between austenitic stainless and aluminum fittings for cryogenic service with a simple thread sealant such as Teflon tape? Thanks for any input.

    Production impact test plates -VIII UG-84(i)

    Review UG 84 ( i ). It'll refer you to several other paragraphs but with some careful reading it should be clear. If you have additional specific questions come back here but, I'd also suggest you consult with your AI.

    Re - Normalizing Sec VIII - 1 Interpretation

    I found two interpretations in the latest volume ( 63 ) that pertain to normalizing P1 material, interesting. The interpretations are VIII-1-15-06 and 08. 06 Q- If a plate is normalized once at the mill and then is subsequently normalized again during manufacturing, does UCS 85 (c) require...

    Code Case 2235 Weld Procedure - Impact Testing HAZ's

    As many are likely aware the requirement for impact testing HAZ's in thicker materials changed with the 2013 Ed. UG 84 (g)(2) Some of you may have seen Code Case 2235 but if not it may be helpful to know that it allows for the use of PQR's qualified by the old rules ( prior to 2013) thru 2017...

    QW-403.5 Clarification

    Or when no impact testing is required. So, if your intended application does not require impact testing by Code rules, the welding variable does not apply.

    banding in CS plate

    When this requirement has been applied we've simply sent a sample of the plate to a local lab and had them perform an examination and provide a report.

    Hardness and GMAW-Spray

    A comment & q's; with true spray transfer it does not seem that low heat input would be an issue unless you are traveling at a very high rate. Have you seen much difference in weld hardness between 70S-2 and 3. I ask because in my experience using the GTAW process, we get much softer welds...

    MT Indications after Stress Relief

    I'm not familiar with the spec MIL you reference but the approach I recommend, and that I take for every job is that any NDE required after PWHT must be done prior to that heat cycle, and, I make every effort to ensure it is done, as it will be done later. Any new variable introduced in the...
