    Tig Welding Carbon Steel

    If you have the budget, and the justification, you may realize some advantages to a plasma setup. You didn't tell us how many feet of weld you have to make, and an automatic setup using either GTAW or PAW requires a substantial investment of time and $. While you could splice a few feet of...

    Hydrotest min. holding time

    Keep in mind guys, the question was related to ASME Sec VIII requirements, and metengr nailed it. It's the AI's call

    welding after PWHT

    A couple of thoughts, Perhaps the thickness of the ring is such that there may be a concern that a great deal of weld is necessary to complete the full pen joint, still, I'm not so sure that you would heat the base to the critical temperature range. We've qualified procedures for dissimilar...

    ASME Sec VIII, Interpretation VIII-1-04-15

    Correct. My apologies. This was of interest to me because I've had many a discussion with our AI and others, including AI supervisors, as to how the rules for radiographing vessels should be applied, and found that the number of differing opinions, is only limited, to the number of people...

    ASME Sec VIII, Interpretation VIII-1-04-15

    Did anyone happen to notice the interpretation referenced above? It seemed a bit strange in that I've always been under the impression that you couldn't jump more than one level of joint efficiency in adjoining welds. The way I see the case referenced in the interpretation, a Cat A with an E...

    ASME Code Stamp for a vessel question

    Well again, I believe it depends what state it's going to. Some states are pressure vessel states and some aren't. If it's going to one that isn't you don't have to have a stamp on it. However, from a marketing standpoint, it seems that stamping the vessels would be a good idea. That way...

    Welding stainless steel to carbon steel

    JLGIII I think I understand (at least in principal) what you were trying to accomplish, but, relying on whipping to avoid zinc contamination sounds like a dangerous practice.

    ASME Code Stamp for a vessel question

    Where is it? What state or country?

    welder test on C/S for S/S use, using C/S wire to ASME

    My opinion is that ASME gives us the minimum requirements, however, as metengr states, this method of welder qualification has been proven over many years. ASME is not going to 'allow' one to reject this method, or they'd have already changed the practice. That said, there may be contractual...

    Is ANSI flange equal to ASME flange

    Are you sure it's not a typo on the drawing?

    Nameplate placement

    UG-119 has several things you may want to consider. They may or may not apply in your case, however, they're a bit lengthy to include in this post. I'd suggest you get a copy of Sec VIII and review them, or consult with your AI.

    Pro-Write

    If anyone out there is using the windows version of Pro-Write, I'd be interested in any comments you might have as to it's opeating characteristics. I've been using the DOS version for years and switched to the windows version when it was first released, but found it to be very problematic. I...

    E8018-B2 Fluxcore w / impacts

    Hey guys, appreciate your input. I've got our local consumable supplier getting me a roll of wire, I believe from Unibraze. We'll run a procedure and try the impacts. For info, Esab says they discontinued their T-5 wire.

    Impact Testing Duplex SS

    When impact tests are required per UHA 51 at a temperature warmer than -320F, it looks like lateral expansion is the only criteria?
