Hi Brad,
I don't want this to become a "mine is bigger than yours" discussion, so I'll try to be positive:
When I say "written by us", it is because we've got a metallurgical engineer helping optimising the procedure (eg. to evaluate the grain growth, which is a problem when it comes to...
Of course I've got proof to back it up. Even got certs myself. Are you qualified for the welding you offer?
Depending on the brand of plane you take, it's probably got Ti pieces designed and welded under my supervision. Do you own a performance car? Chances are precedures were written by us...
It's been well over a month now since the 2018 version of EN 1090-2 has been published in the UK, more than time enough to at least have it read through... How do all of you RWCs like the changes?
I've seen Ti welding at less than 5 ppm O2 on ultrasonic cleaned pieces and filler, still sticking. I doubt dirt contributes to the sticking. Gotta fill hard and fast, on the leading edge of the weld pool.
OK. this is a terminology discussion.
If the included angle (had to look this one up!) is 60°, would you agree that it is a better/easier geometry to weld than a 45° included angle ?
weld will bridge in the 5mm wide opening faces. I'd agree if it were larger. Anyway, a 30° bevel (meaning a 60° open angle), less or none at all would be far easier and less prone to root LOF, and cost exactly as much. This is asking for problems, where better alternatives are easily available.
Sure about that? What if I disagree, and say CE marking is needed anyway, or not at all, depending from what side (buyer/vendor) you look at it? Welding has got nothing to do with it.
Either way, for low carbon steel and a simple construction like that, I'd have a go at it myself, especially if...
Are these pictures of the weld as welded (and not cleaned up)?
If so, that's actually a more than decent first try of Ti welding.
Mind, cleaning up Ti has no value whatsoever, as discoloration means problems throughout the entire wall thickness instead of just surface contamination as in...
The Belgian RWC course is a very condensed summary of the IWS course, with all modules as prescribed in https://www.ewf.be/exemplos2/listagem/welding_coordination.aspx pertaining to carbon steel (so it doesn't apply for stainless of ally construction companies). If you're interested (and you...
This is a very easy and efficient way to get an idea of the base material. If you can't file the filler material away, don't even bother to weld it without specific instructions (like preheat of Ni-based filler).
I'd have it spray filled (think of HVOF). 100% guarantee of success without having to know for sure the type of base material, and no problem drilling/tapping afterwards.
If you need locating pins, you can use copper inserts during filling, in their original location, and drilling/reaming them...
The 5mm 45° bevel is a bad idea, I bet the root isn't as it should.
No prep is the most economical solution (and equally good), however whoever decided prep was necessary should've chosen a smaller prep angle.
I've recently done some gigs in the UK (1 small one, 2 of over one week of work), and following these I've been asked by the UK NoBo that did the assessment to do auditing for them, which is something I am not at all interested in. I much prefer the fabricator side of things. However it got me...
I'm talking about an RWC that can really help out a company when it's got welding related problems (and not only welding standard related issues). Someone that knows his stuff.
But if the UK runs on 2-days course guys, I doubt you really need competent RWC's... Would be a waste of time.
EN 1090 is for construction work, ASME IX is a boiler and pressure vessel code...Not really interchangeable.
Anyway, came here to see if what I heard is correct: Apparently, there are not many welding coordinators in the UK. Either they are good, and they serve dozens of companies (meaning they...
Does BS 4872 is still actually used in the UK?
Wouldn't EN ISO 960-1 be the better choice?
I'm familiar with the BS standard, but I don't really see the advantages of it - unless UK weld shops still accept those or ask for such certs.
Maybe a bit late to the party, but it says nowhere that a welder needs a digital read-out.
It's perfectly possible to calibrate an old-school tranformer type MIG welder without dials, and using those machines for PED, EN1090, ... works.
