These guys are talented, I have been in the Plumbers and Pipe fitters Union for 32 years and they encourage uphill vertical, but a lot of our pipe welders do down hill root passes and there is nothing wrong with that. I do both and really the down hill root pass I really prefer now after years of doing up hill vertical root pass.
Gravity is gravity, I am almost sure that going dawn is not ok, seems basic from sound, i always start down e going up, finishing on the top e then restating dawn, never faild, i weld low pressure, 0,5 gas ,end water max 6 bar ,pipes max 16 inch, 8mm ,end 4 ,6 ,8 ø -4 mm
These weldors know exactly what they are doing. Down hill is the norm for cross country. These guy's don't walk, they run across country. Damn good hands the pipeliners are.
Check the keyhole at 2.23 when he changes rods. He is dragging that keyhole down with him, the weld runs from the inside out. Bead welders are the most highly paid.The helper then grinds the weld and leaves the bead with wagon tracks. The next step is the hot pass, where the stovie cuts out the wagon tracks and leaves an inverted vee shape behind to be buffed out with a wire wheel, by the helper. Next come the fillers and cappers, who finish off the job.
Sehr schönes Video !!! Welche Schweißaggregate verwendet Ihr ? Wir haben welche von MOSA. Verwendet Ihr Elektroden von Phoenix,Oerlikon oder Erotrode etc.? Wie ist die Bezahlung bei Euch ?
Done all kinds of welding myself from underground steam to stainless to orbital. Been in power plants, trenches pharmaceutical plants and everything and anything in between and have learned that you gotta find what works for you and stick with that and be able to do whatever procedure in any position you're thrown into. You gotta be able to adapt to any gap thrown your way, if it's tight rip it in hot down hand and if you get a bigger gap then turn your heat down and go up. Local 537BOSTON
Obviously You have never read a weld procedure and never worked to one . This is the criteria by which the welding is done to meet the standards required by the contract .Metalurgical,ultrasonic X-ray ETC..
Mig is used sometimes in fabrication shops. Outside you'd get hella more porosity because your shielding gas would be blown away by the wind. I think or also believe the shop would have to ndt test before usage Mig and that costs thousands of dollars. Stick works best outside especially E6010 for the root pass.
I'm no pipe welder and I'm not looking for a youtube argument but wouldnt they weld this with something like a 7016 or 7018? Its just I'm not sure if an electrode like a 6010 - 6013 would be acceptable in Australia so I'm just curious where these welds are done and what they're for?
Looks like those 2 guys prefer a wide gap for the root pass. We always ran a tight gap and crank the heat and skate along laying in a small bead with less irregularities. But ..if that works for them... fine
I mean...why it should be a gap anyway ?? or it's because of the high pressure (h.p) pipe that we need to add a groove gap for the root pass ?..idk..i think that it just make the job more difficult.
With stick welding there is a need for at least a slight gap to bury the rod in the gap and assure complete penetration.However if there is no gap and the land face is thin then you could weld with zero gap and butt the 2 pieces of beveled metal together and weld it that way as long as the end result is the same.Over the years, as I welded more and more pipe and experimented when I could, ( always experimenting when you can ) I found it is better to weld with what is considered a tight gap or very tight gap while often enough the gap closes up completely as the pipe begins to get hot and all the more so with small diameter pipe...which is actually a good thing and all the more so with small diameter pipe as having a wide gap on small diameter pipe is all the more challenging to weld because of the joint area becoming to damn hot and you have to either turn the heat down too much to control the weld puddle or skip ahead or do a lot of "whipping" and manipulation of the arc to control the excessive heat and the large keyhole developing and excess molten metal involved.If the gap is tight or non existent then you can perform the weld up hand or down hand by jamming the rod in-between with a degree of force while moving faster while working the arc in-between and working the angle of the rod so there is not excessive build up on the inside of the pipe so that the root pass sits say 1 mm high on the average and you can see the uniformity of the bead all around the clock ..so to speak.When performing an up hand bead with a tight gap or no gap with an appropriate land thickness you have to avoid the rod angle being point back at too steep of an angle or you will create excessive build up of the bead especially starting at the 4 o'clock to the 2 o'clock position while that particular area of reverse clockwise positioning is a little bit tricky trying to come up while lifting your arm and elbow while also rotating your shoulder and at the same time more or less forced to rotate your hand in a manner that the rod length stays at an angle of about 10 to 20 degrees to avoid excessive build up and undercut that will occur if the angle of the rod is "tilted" back too much.When told I had to weld up hand on all the pipe and according to the codes enforced by the welding inspectors on the jobsites, I learned to do as they asked but I performed the up-hand root pass bead in the same or similar manner as performing the root pass bead by way of down hand positioning and simply got used to comfortably dragging the rod "up" and around the circumference of the pipe and learning to perform better stops and starts relative to what occurs when you "re-fire" the arc and start to blend the arc and molten weld puddle into a stop / start keyhole point and performed in the up hand position verses the down hand positon.Try it and you will soon learn the root pass welding can be performed in such a manner while it will become a matter of routine after the initial experimentation and the learning curve and finally with experience. Also, just for fun try to do a cap pass with 7018 welding rod ( Down Hand ) while the down hand 7018 cap pass looks smooth and uniform.Cheers

@Legatus777Legionis kommt drauf an wie der Spalt ist und die wand dicke.1.geht fallend viel schneller als steigend und mann Brauch nicht so viel elektroden!mit den einbarnd bin ich mir net so sicher aber Heut zu tage wird auf hochdruckbaustellen nur Fallend geschweißt und nur die einbindungsnähte meist mit KP geschweißt!
but the guy am seeing in the video is welding down-hand in the penetration bead am quiet confuse if the weld won't be slag inclusion will have good penetration.
una pregunta este es el pase de penetracion ,se puede decendente y ascendente,la norma lo permite,segun lo que me enseñaron es que tienen que ser descendente,por favor me pueden dar una explicacion
Well my friend, it also depends on if you weld in a Union, now I'm not exactly sure what Union this is, but I know that these guys go through training, I'm one of them that is in school right now for it, they know how to control the slag and they don't use the welding rods like 6010, 7018, 7024, they use welding rods that are made for pipes to be welded, that don't drip in slag when you weld with them
Die Erdgasleitungen die wir beim LT verlegten in Russland haben ein Durchmesser 1420 mm innen! Und die Wurzel wurde bei uns ebenfalls fallend geschweißt ! Und es heißt Elektroden und nicht Schweißstäbe ...
Bei sowas müss eine vollautomatischemaschine schweißen ? Weil die Rohre selbst werden vollautomatisch von pulverschweißmaschiene geschweißt von beiden seiten. Ihregendwie anderes gelernt. Schweißen mit einen durch zug wegen Schweißnahtunterbrechungen. Schweißnaht prüfen mit einen ZfP verfahren. Wird nix gemacht ob die hier ein stück blech schweißen da wird öl gepumpt oder nicht ?!
Hell I'm in welding classes and all we do is uphill, downhill, vertical up, vertical down, and overhead, downhand? Must of been made for girls I agree with you on that, if your gonna be a pipeline welder, you have to know everysingle welding position there is, downhand I am pretty sure, is not a welding position.
1/4 inch gap? In my world that is unacceptable, I have been welding pipe for maaaany years, and if a fitter gave me a 0.250" he would not be around long. If a welder was to as for a 1/4 gap in my world, chances are he would be run, as the extra filler metal, heat input and time would not be acceptable on a tight time-frame. I have only ever seen a handful of procedures that even allow such a large gap, and those are certainly not used low expansion carbon steel alloys.
The root pass was flowing, excellent
I am amazed of the steady hand, closing the hood and still knowing where to begin to weld
I love this work. ...
Da gusto ver a esos vatos profesionales, soldar....

Downhill is supposed to be easier than uphill... do they give you a choice in your union?

Seria bueno que presente el acabado final para ver como queda
@Lawrence Hanlan i believe its this way. Root pass-6018 1/8".
Filler and cap-7018 3/32".
Hope this helps answer your question.
6010 bead
8010 fill and cap
Do pipeliners ever use MIG process? Other than submerged arc, just seems less chance of porosity with less stop and start? Thanks
Mig is used sometimes in fabrication shops. Outside you'd get hella more porosity because your shielding gas would be blown away by the wind. I think or also believe the shop would have to ndt test before usage Mig and that costs thousands of dollars.
Stick works best outside especially E6010 for the root pass.

hasslefree omg that was a very long comment ! and very informative ! thank you so much for your time !
They are welding conventionally down hand, OK for tie ins but mainline tight gap crank it up and drag the bead in
looks like the stinger is a harbor freight special

What kind of electrodes, gentlemen are welders?
Nesse caso da tubulação quando a posição da solda fica na vertical á solda pode ser feita de baixo para cima ou não ?

una pregunta este es el pase de penetracion ,se puede decendente y ascendente,la norma lo permite,segun lo que me enseñaron es que tienen que ser descendente,por favor me pueden dar una explicacion
Creo que en la raíz es descendente en una línea y en los empalmes especiales son ascendentes

son muy buenos los vídeos
que tipo de electrodo es
tipo es aws er6010 e 8010, electrodo de revestimento celulosico,soldadura desciendente.
Die Erdgasleitungen die wir beim LT verlegten in Russland haben ein Durchmesser 1420 mm innen! Und die Wurzel wurde bei uns ebenfalls fallend geschweißt ! Und es heißt Elektroden und nicht Schweißstäbe ...
Good job guys
Qual e ammperagem que vc usa na raiz
Hermoso!
Good wilding 👍🇩🇿
30inch, 7 rods for the bead..not bad going...lol.
downhill root used to get me in trouble. is the final pass done uphill?
weather conditions make stick welding ideal
well done good job
Thing is, a stick welder is much more portable and doesn't require gas or anything and doesn't care how the weather is either.
Nota 1000 pra vocês.
From top to bottom root START??

Ok so my Q is how much is the Hr pay to do this
Hi, I am a welder. I am looking for a job with a degree in welding and 8 years of experience who can help me 😔😔
cest formidable
But they whip 6010 downhill for the cap on pipeline :p
@Lawrence Hanlan i meant 6010 for root pass.
To big of a gap!! Way to much rod going in there

Any repairs will be done by welder who welded it ,if he does not get fired for busting one.
if you close it up you can get more than 2" a rod
very good Welding
the best way to weld....fallnaht
