Looks great, solid, and real efficient. Only thing I wonder about is would the qc guy not say anything about all the start stops lined up? Forgive my ignorance but I legitimately want to know. I’ve always been told to stagger them and have seen people busted out for that but only by a specific cwi at trade school during AWS cert tests. I’m always looking to learn something new.
If your using scratch start tig probably is best to stagger your starts and stops a little bit as you might have tiny tungsten inclusions in your starts and wormholes in stops if you don’t grind them out correctly. But if you are using 4 touch or 2 touch tig no need to stagger your starts and if your have enough slope out you shouldn’t even need to stagger your stops either.
Just remember, passing a test is only a license to perform your 1st weld for an employer and all bets are off for passing or satisfying the specification/Coder for every weld after 1st!!
A dumbas way to live life thier is no sustainable industry alive that can live by those standards and we are not even contractor we just do the dirty work and the crumbs pay anyone who doesn’t realize that about the industry is an diot
Not wire brushing Inbetween passes will just make the weld pool a bit dirty and not clipping the wire will just make the first inch a bit of a dirty weld pool if that makes sense. Wont cause any defects if it was to be x rayed.
Why did you use 1/8 filler wire instead of 3/32 wire? On the 3/32 lay-wire technique just curious dose it push more filler wire into the root so the root isn’t flush?
I did a weld test recently where I was told *not* to tack the root and feather. Nothing was supposed to go in the root until it was fully set up and put on a 45 but the guy administering the test let it slide. Oops.
Nooo, really it depends on the company and the standards they follow. Some pipeline welders have to recert every 6 months. The company I’m currently working at recerts every year
Depends what code your working to Americans work at ASME which I’m not hundred percent on but in the UK and the rest of Europe we work to ISO 9606 which states your qual goes void if you haven’t done that weld in 6 months once but if you have been consistently doing it you will have to re qual after 2 years.
I'm not a welder, i have over heard in the past about having to let things cool to keep the inner temperature below a certain level. At what point do you have to worry about that before letting it cool for the next pass?
If there is a interpass temperature stated on the WPS and you would be given a tempilstik or heat gun to check the temperature of the pipe as your welding.
Would you guys ever take a look at filler metals? Looking at different codes and what’s required for certain filler metals like T-8 welding wires vs T-4? Why it’s used in seismic zones, etc? Also going in depth with engine driven welders on a suitcase, which is a profound thing for welders on structural jobs, a lot of new guys simply don’t have a clue because in school they teach you off a miller XMT with 10’ of brand new cable, you don’t have to account for much voltage drop off, but in the field you might have 150’ of corroded cable on your machine so when you set it at 22V, your really only getting 18.5V. Videos not for people in school, but people who are breaking out and have never seen this kind of stuff in school. Also, you know how you guys do mock up plant work? You also should do a mock up pile splice for both pipe and H piles, except you have the students rigging, using hand signals they learned from the course to get their pipe or H piles on location, then welding it and doing a mag particle test. It would be a process that would really prepare new welders for what’s to come, especially rigging and crane hand signals.
Question....does it matter when you weld pipe how much weld convexity you have inside the pipe? Ive heard too much sometimes may disturb gas flow and or create turbulence in the pipes pressure, any of this true?
Depends on the class of pipe and generally the OD size of the pipe. Pipe from 25 to 73mm ( 1” to 2 1/2”) will allow only 2mm ( just over 1/16) and pipe greater than 73mm can have up to 3mm or 1/8 internal protrusion into the bore. The idea is to have least amount of restriction as possible, especially on the smaller bore pipe.
@@unclegeth7899 Coal plants have been closing at a fast rate since 2010 (290 plants closed from 2010 to May 2019; this was 40% of the US's coal generating capacity) due to competition from other generating sources, primarily cheaper and cleaner natural gas. I was in the trade for over 15 years and I withdrew because jobs were getting less and shorter.
@@Keef_Chief86 we only have a few power stations now in the UK off the top of my head Drax, torness and VPI that are coal or biomas powered so there isn’t much boiler tubes that need welding anymore as from what I’ve seen on hinkley point c there won’t be any or many on there and sizewell c and wylfa b will most likely be the same. Like I said I have a coding in boiler tubes but I’ve only ever been called to do them once on drax so it’s not exactly my field of expertise.
Anything that is purged for example stainless, 9% chrome and Inconel Ill cut and dip (keyhole technique). But for carbon and 2% chrome for example have you tried setting a 3.2mm gap put a good 1.5-2mm root face and use 2.4mm filler and do a constant feed into the weld pool weaving slightly up and down to fuse it into both edges.
@@118Wilson 1.5- 2mm root face on TIG is the same for every WPS that works to ISO 9606 standard, means you get a root that is just over flush which is what they want if you are welding high pressure steam pipe or tbh anything in general as your not restricting the flow of what’s going through that pipe. It’s also a much stronger root to explain if you weld a with a 2mm root face you have to 2mm of material actually fused to the base material where as you are welding feather edge you have 0.5mm maybe less actually fused to the base material.
@unclegeth7899 just never do a root face in the workshop I'm at and we are making pressure vessels and tanks. alot of it is ASME 9. All the WPS in the workshop call got feathered edge. I'll maybe give it ago when I have free time
@@118Wilson I mean i don’t work to the asme standard so if your wps calls for a feather edge crack on. 50% of the time I’m welding feather edge anyway because half the pipe fitters can’t be bothered to put a landing on 😂. I can say from doing both rooting TIG with a landing is a hell of a lot easier though.
For a test don’t you wanna spread the heat out and let it cool in between. Like I get trying to do it fast. But couldn’t fast keep too much heat in the part and run a risk of over cooking the steel and making it brittle?
You are right with not letting the base material get to hot as it does change the grain structure of the material which in turn does lead to a more brittle material. But on a test it depends if there is a interpass temperature on the WPS. I’ve taken 2% and 9% chrome, Inconel, stainless tests and there has been no interpass stated on the wps for the test as they are only testing the weld but on site I’ve welded those materials and I’ve had to follow a Interpass temperature and other times I haven’t had to follow a Interpass temperature so it depends on what’s going through the pipe when it’s in service. So for example a pipe with high pressure steam going through it a Interpass temperature would be followed as a brittle material would be no good for that application but a pipe with say just water running through it wouldn’t matter so much if the material is brittle.
