The first patent on the submerged-arc welding (SAW) process was taken out in 1935 and covered an electric arc beneath a bed of granulated flux. Developed by the E O Paton Electric Welding Institute, Kiev, during the Second World War, SAW's most famous application was on the T34 tank.
thanks for your comment.However you dont know the application, and as such our insurance approved/ metallurgical test results specify the wire diameter (bead), the speed of rotation, volts, amps, flux, & steel thickness to give optimal tensile & weld flow/fusion, which is demonstrated perfectly is the quality of weld being achieved. Welds are subjectd to NDT. use of freehand MIG would in no-way achieve the the high quality standards we require. Our welded vessels in service operate at 60BarG
J D First off that is an automatic welding system not a robot. Second where I work at many times people who run automatic welding systems make more money than people who weld by hand. Third it is sometimes about quality. It can take years for a person to match quality with a system like this and if you can match quality you can't match speed. In the department I weld in I am the only work center that welds by hand. I do the low volume and oddball stuff that the machines can't. I can match quality with the machines but I am a 20 year welder and it took 10 years of busting my ass to get better to be where I am. I run the automatic welders sometimes and they blow me away on speed. Sometimes I call off sick the automatic comes to work everyday and does not qualify for the pension plan. It is better to trade 2 jobs for one than for the company to move to some shit hole country where a guy will weld for 2$ a day and no restroom breaks. You are living in a dream American wages are very high so companies need quality and speed from the American worker or we are all in the cheese line! duh
We call that a gnat killer, because it is so smooth if a gnat tried to land on it he would slip off and break his neck. That is so slick the paint won't stick! Ok I'm done with the jokes that is a really nice weld, I dig that seam tracker. I run an innershield wire call NR-212 It could weld that smooth if I could quit shaking, but it leaves smoke all over the place.

What material are you using for that flux dam? I would like to come up with something similar for smaller diameter pipe welding to keep the flux from falling off the front side.
the vessel is bolted on a turntable that's what it's called and there's a speed controller on that you set the speed once you get the desirable world that you want
What flux do you use? What grade of wire? Is it an EM12K wire? We manufacture and export both fused and agglomerated/bonded fluxes to the USA (fused). A UK based company with its subsidiary in India has started using our fluxes for hard-facing of steel mill rollers. Is there a scope for us to supply you with flux-wire for this application?
Granulated flux, it shields the arc from atmospheric air intrusion and also acts as a cleaning agent in the weld pool. Next to Tig ,done right it is among the cleanest welding operation types in existence.
+AutomotiveTanks Ltd Thanks for sharing this great video. I love to see the highest quality work. Most places would have been cheap and lazy and only put one pass on this vessel. Thank you for taking the extra time to put a cap weld on that root. You got me at first, I thought that is a very long over lap then I realized you were putting on the second pass. That second pass really helps stress relieve the root and ties right into the warm metal. I don't know what these tanks are for, but I have owned many air compressors and the tanks that have a nice reinforcement on the welds never give trouble. The cheap compressors with just flush way to hot welds always give trouble in the heat affected zone!
That's too big of a weld for such thin material! It looked to be about 6mm , so there was definitely no need for such a wide bead and no need for 2 passes. That kind of a vessel would have been better of being welded by hand with MIG on a set of rollers with or without speed controls.

This welding technique looks clean. I like the looks better than stick, tig and mig.

I am also a submerged arc welder myself. I mostly welded with 3 welding wires/heads.
This is a dream welding for a welder!!
Those who want to pretend this type of welding he or her have some confident in this type of welding..
The 8 dislikes came from people who did not have a clue what they were looking at or they don't like quality!

With a laser pointer?! now that's fancy! I had to just mark a line on my nozzle and eye ball it
I Made a makeshift guide with 1/8th coil
Noway~~. Put some wire on the nozzle and make straight the wire with filler wire

Looks like only Schedule 40 pipe? Sub arc really necessary? And do they do the same process with the seam?

Felicitări
Good welding ...👍
Super
Thanks for sharing though I don't understand why some thumbs down???
Were is? How much they pay you for hour? I di it this kind jobs long time ago in my country.......nice job
Thats 1 nice contiunous weld nice job !!!
Galing nmn ganyan pla, thanks for sharing
I appreciate your work.But i have 2 doubt
.How r u achieve this speed to rotate the tank?which motor u should use?
the vessel is bolted on a turntable that's what it's called and there's a speed controller on that you set the speed once you get the desirable world that you want
sagar mendale the tools of a service-connected or bolted onto his collie position of the position and has speed controllers on it
How about max interpass temp? Did you have any?
that is a thing of beauty
looks good

Would like to get more information on the laser alignment system you are using.
I saw the welding line at first, clean and twinkling line :) I had wondered the reason why used the sands.
That sand is flux similar to the flux on on welding rods. It’s a wire feed system.
is that sand on top of it
Granulated flux, it shields the arc from atmospheric air intrusion and also acts as a cleaning agent in the weld pool. Next to Tig ,done right it is among the cleanest welding operation types in existence.
Machine name and price for India plz provide me🙏
good for filling and capping.
I do but with two wires a/c and d/c ...I weld suction piles
I'm living in London, can I find a job like this in here?
I was a Welder in Portugal, MMA,MIG/MAG FF and Saw for 24 years, I'm 43...
I would like to no about machine manufacturer & its detail.
Throw a flux recovery system on that bad boy.
any input outside a greedy education recruiter and their fabrications would be very helpful (:
good boss...
good machine
thanks, much appreciated comment. There is one fitted but its out of shot, flux is very expensive too waste!!
Rester sur la partie la plus épaisse avec le laser
how much ?
At least SAW would secure you from inhale too much poisonous air

👍👍👍

with laser, cool
looks cool
this would likely to be near 3mill wire 6 mill that's a lot of wasted steel
