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...

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

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...

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...

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...

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...

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.

Where is it? What state or country?

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...

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

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.

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...

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.

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

I agree. Visual and RT inspections will be performed. Go figure.

The only explanation I have is ignorance. I don't mean to be facetious, I relly believe that many people in the position of making these decisions, really don't know much about the process and in many cases don't know much about welding in general. I believe that fluxcore got a bad reputation...

Thanks for the lead. Unfortunately, it looks like this is 'unobtanium'.

I agree with metengr. I assume you're concerned with welding these materials. As you know the P1 material is .5 Mo, and should be readily weldable, P12 and P22 are Cr Mo alloys and they do require a higher preheat. In my experience most welders tend to skimp on preheat and maintenance of the...

Does anyone have experience with GMAW spray welding of Dupplex SS? The procedure must meet the usual ferrite restrictions, impact tests, and corrosion tests per A 923, as well as the usual mechanical tests req'd per Sec IX. I have a FCAW that is qualified but this particular customer doesn't...
