Sub Arc is the same as MIG but uses a granular flux poured over the arc instead of gas shielded. Ran one in the 80s making bridge girders. Duel sub-arc feeds on each side welding the web to the flange in one shot all 125 feet. Screwed up once forgot to close the flange guide rollers when it changed widths. Welded 10 feet off center. Boss man handed me a grinder. Learned to keep me eye on the flange change. 😂

My Dad was welder, working to built Navy ships back when one wage earner could support a family. He was really good. Was the guy they brought in to rework other guys’ flubs. Later he worked on pumps for nuclear reactors. Had second jobs. Never had a problem finding one. He’d go in, take a test, and be hired.

I am 13 my grandfather was a ironworker for 40 years and he started teaching me to weld when I was 7 and I can now make welds not as clean as that but pretty clean for my 6 years of welding. All my friends think am a nerd because I can use a welder, angle grinder, asleden torch(pretty sure I spelt that wrong) , as well as a plasma cutter. Most of my friends don't even know what those are and it is cool to be able to read the comments on videos like these and be able to understand what people are talking about.

Young man - my salute to you and your grandfather. I'm about to retire from an almost 40 year engineering career - like you - my father taught me to be handy, and he stressed the value of an education as one of the few things in life that once you'd earned it, no one could take it away from you. My childhood dream was to work in the space program - I achieved that (Space Shuttle, JPL, SDI ("Star Wars"), and went on to a second career in medical devices. You are privileged to have at your fingertips the greatest storehouse of information in history - the internet - but you have to process, assimilate, and use it for it to become your knowledge. You're on the right path, and following it diligently is how you will become great. Nurture and grow your curiosity, your thirst, your need for intellectual and physical advancement. Learn to do the things that others can't. Be that nerd - the one that always gets called when one one else has a clue. Improve and polish your communication skills - when you're an accomplished adult, no one will care where you went to school or what your GPA was - they'll judge you by the words you speak and write (acetylene))) and by what you can actually do. Combine this with a kind and gentle character, a healthy sense of humor, and a thick skin, and you'll be as fine a man as you can be. The journey won't be easy, but every life is a struggle - even for those you think "have it all". I wish you the best - I hope that someday when you're about my age, you'll look back and remember this, and think, "that man told me the truth".

[@numberpirate]

This is the method of welding that the US sent technical advisors to the USSR during world war 2 to show the soviets how to make really good welds on the hulls of the soviets tanks. It increased the durability and decreased the production time of the tanks so that the germans had a really bad time on the eastern front. As an example the T-34's made before the war started were good but once production speed was increased, the T-34s were susceptible to having their hulls crack at the joints between the massive plates. So these tanks were literally cracking apart after being driven only 10 or so kilometers. And if they got hit by a high caliber glancing blow the hull would be ruined due to it cracking along all the seams. Afterwards, both speed and quality increased massively allowing the tank factories to outproduce the Germans by a factor of almost 10.

[@dchawk81]

I wanna see the rotisserie that spun those soviet hulls in a circle.

[@jesselee290]

[@timebert6141]

Evidently some people have never seen seem welding equipment for straight line runs. Some people call that track welding equipment. Some of that equipment has multiple adjustment points to follow very irregular seams. I have seen subarc welding equipment with a hand held torch. The massive slag blanket and unmelted flux really help to slow the cooling rate in the weld zone and heat affected zone.

[@sophiewilliams7582]

Haha, this takes me back. Spent 9 months as the offsider on the other side of those 4 ft diameter cans knocking off the slag strips with a hammer (point and chisel-point). Steel was 3/4" thick, and usually took 3-4 rotations to fill the gap (was a wider gap) with cap weld on top to finish. Looks like you don't have a problem with slag strips these days. It was 35 years ago for me. Welders were still Lincoln Electric though, but no fancy digital displays. More or less just a knob for volts and a knob for amps. Nice work :)

the flux granules can be reused , but they need to be replenished. they are bits of flux that get melted in the weld puddle in order to form slag that will float out impurities in the steel as well as protect it from oxygen. as for cost effectiveness, the argon is cheaper alone, but the flux is more cost effective as there will be better welds and less porosity. the argon shield is not as effective outside as even a slight breeze will blow away the shielding gas exposing the puddle to oxygen.

In Ireland this is known as Submerged Arc Welding and according to the steel fixer that attempted to teach me how to arc-weld back in the early 1970s the technique was reputed to have been perfected by a team of welders and engineers at the Haarland and Wolfe ship yard in Belfast (wher Titanic was built) and was used initially to butt weld large sheets of plate steel together to form ship-decks etc. Nice demonstration video.

I used to do this sort of welding on a tank welding machine back in 1973, welding hot water tank bases. It does a very neat welding and no sparks escaping.

[@hellsingdudeman]

Do this every day on round seams on pressure vessels. Far from perfect, I think its a popular process just because of the sheer amount of metal it can lay down so fast. Alot of ours have to pass x-rays and have a certain amount of imperfection or less. I believe it has a good amount of porosity, but so much is passable. I believe its been around since the 30s, and I wonder how ide never heard of it until i started this job.

I welded Sub-arch for awhile, every wind tower is welded sub-arch. The kitty litter looking stuff is Flux so no shield gas is needed. When I welded we used 2 ,1/8" wire. One at 90º for penetration at 650v 31amps. The trailing wire was 550v 29amps. Trailing was fill and the pretty cap finishing weld. Our tip was set at 1 1/4 inch from the bottom of the crevice. Our average steel thickness was 22mm.

When I used to repair welders I had to replace a transformer on a 1500amp Lincoln welder used for SAW. After the repair I wanted to make sure everything was working as it should so I went to the factory where it was installed. The operator was joining two 1" I-beams and was running around 1000amps. I had never seen SAW before just MIG and TIG so I was expecting to get a nice sun tan. I put on my welding helmet and stood back a few feet. Needless to say I got a few laughs at my expense.

Car exhaust is CO. Carbon monoxide. It is not the same as shielding gas. This process uses an agglomerated flux and a solid wire. The flux, which looks like sand, acts as the shielding gas, much like the flux in SMAW. So no gas is needed.

It can be a bitch/finicky sometimes depending on how it's prepped. Our shit is pretty clean so we don't even etch the oxidation off we just go right to welding.

[@MadMetalShop]

A lot of the 1/4 to 1/2 we weld we run around 24v at around 200 amps. The old standard push pull machines would do the same but at 26v and with lots of spatter. so these new machines will weld the same thickness with better quality using less power :-) 100% duty cycle.

What a great process, not seen that often today only in heavy industry or shipbuilding. In the right application no other process can compete with its deposition and quality, just a pain with the flux and slag.

[@phil9398]

I miss sub arc welding. Did a lot of bridges in the early 80's with it.

[@Largewhiteguy1]

Actually, Tank builders are using sub arc to weld horizontal round seams, using a nylon or canvas belt on rollers positioned about an inch of so below the seam to catch the flux and allow it to accumulate above the wire and arc, therefore submerging the arc. It makes really nice welds even in this position and if you are careful not to blow through thinner material, can do in 3 hours what would take 3 welders 2 days to complete, and do it with very high weld purity.

lots of things can cause pin holes. you can use a flux core wire with the SAW process and it will give you a better chance of obtaining fusion and less of a chance of contamination. As long as the metal is clean a solid wire can be used with the SAW process. Using the FCAW process with a argon/co2 back up is an excellent welding process. SAW is great for long welds in the flat position but FCAW is much more versitile.

yea, it's a cool vid. I have done some SAW before but never on pipe with a rotator in the field. I was actually curious about how you recover the unused flux. Is it just some type of hopper set up on the back side of the pipe?

[@africanelectron751]

Amazing how clean the whole process is! Do you reuse the excess flux?

[@africanelectron751]

Thanks dude!!

[@africanelectron751]

Im curious, is there any shielding/flux on the inside of the pipe?

[@dougankrum3328]

Some Sub-Arc machines have vacuum cleaner hose that sucks up the non-fused flux and returns it to the supply hopper.

[@SoEpicreviews]

they do have some sub-arc pipe machine where i work that does inside and outside shielding /flux but its spiral butt weld
