Aluminum fuel tank repair.

[@thomas4844]

Love you stacks of coins. Aluminum can be difficult but you make it look absolutely beautiful and easy. Love his channel Greg.

Been binge watching this channel recently. Not gonna lie, kind of making me want to quit my desk job and get into trades. Should probably start as a hobbyist though. All these tools aren't cheap 😂

I'm impressed how well your dogs are used to all sorts of shop noises! Grinders make a, well, grinding noise even to me, and dog ears are much more sensitive to high-pitched noise.

I heard and saw the results of a "it's diesel so you don't need to worry about purging it", it was a Cat 777 tank, he was lucky that he got a few feet cut before it blew, still made everything round and therefore scrapped the tank, but didn't kill anyone.

[@joefalmo5528]

The fumes are what kill us , usually I will remove the caps on any fuel or hydraulic tank and if possible, I’ll leave them sit outside a day to help fume off whatever is in there, hydraulic and diesel tanks. Don’t typically explode from welding, but they can !we measure the oxygen level in the tank , no oxygen no boom. Gasoline tanks are to be treated differently ,gasoline fumes for quite some time. Sometimes I will stick the exhaust from a vacuum cleaner in a gas tank and let it run for two or three hours, and then I will probably put argon in it before I weld it, that’s how I was taught to do it, and I’ve never had a problem, never put water in a tank, thinking it can’t blow up, by putting water in the tank, you can condense the fumes to a small area and create a bomb, fuel tanks are dangerous, and not for everybody to weld on.

[@marklazar2415]

Peterbilt tank doesn’t need purging, your repair needs 3/16 “ plate matching where it’s cracked going down about 6” by 10” wide . Take fittings out before welding they can galled themselves when you take them out to redope . The reason weld broke was the Equiflow pipes going into tank move with the slosh of fuel, been bad set up from begging, worse since PacCar bought them out .. When tank crakes by seam drill ends grind crack weld grind flat take 3/16” 3003 Aluminum bend to shape 12” length at least 2” wider on each end of crack clamp in and weld .

[@yaykruser]

Why not use Co2 ? much cheaper...

[@motoz3939]

Yea I just open them up too and refuse gas tank repairs but diesel like this is good quick cash usually. Fixed more tanks than I can remember. The oxygen monitor always a good idea. Whatever floats your boat and doesn’t blow you out the water!

[@seantbr2019]

Purging the tank with argon is a great idea two birds with one stone

[@parkerbirch5286]

Thank you for all your efforts , love watching your videos.

[@Asomesauc]

Great video really enjoy the aluminum you've been doing

[@garthland]

here in the northeast it's common for them to corrode holes where they mount,the repair is to 'band' the tank with a 5 or 6 inch wide strip around the circumference. As long as the vessel is 'open'-fuel cap off,plugs out-there is no need to purge them. All they do is smoke a little at best,diesel is pretty inert.

[@samuelspencer9194]

What my dad did was run a car exhaust pipe in there and let the carbon monoxide fill it up and then he would weld it but again that was years ago love your videos be safe and have a great day Sam

[@davidmerullo551]

diesel exhaust is the best. used that a few times to weld up a gas tank.

[@bombardier3qtrlbpsi]

I see your two helpers on the floor there slack assin! Nice job 👍. I could tell you some stories of fuel.gas. tanks that went boom and propelled themselves across the floor 😄😃

[@crbrepairmotorcycles6608]

You need a that was easy button 😅 Was cool how the match went out 👍

[@petersipp5247]

You can weld either handed. That’s a skill I taught myself too. Be handicapped only welding one handed. Nice job !

[@davidspin5353]

Cool trick about the match! I also weld and have a shop and mobile rig.

[@JonesMetalCraft]

Thanks for showing/explaining the purge technique. Just curious how long that took to purge.

[@OFW]

Probably about 5 minutes. But I let it go for 15 minutes.

[@Valleymobwelding]

I just made the same repair on the same tank with the same crack today. Did it the same way

[@Valleymobwelding]

I've heard of welders drawing vacuum on tanks prior to welding. Have you heard of this? If so what would be a scenario where this would apply

[@michaelgray7302]

Have you ever tried tungsten wheels in doing that type of work I have found it very successful very quiet and Clean. Michael

[@glenngosline1710]

Great job as always

[@HeavyHiitter]

Great work! So If the tanks is purged with argon, the tiny bit of diesel on the tank walls cannot ignite due to no oxygen, making it safe to weld without having to wash out the tank?

[@OFW]

Correct.

[@jasonchampion9932]

Thank you!! Good job 👍

[@Geezer661000]

good vid. About how long did it tank for the argon to purge the tank?

[@OFW]

About 4 minutes. But I like to make sure

[@Okie-Tom]

Nice work. Can the purge like that also be used on a gasoline tank that is steel or aluminum?

[@OFW]

Probably, but I will not ever weld on gasoline or propane tanks. It’s not worth the risk.

Question< someone brought me the same tank. Saddle wore on the tank and cracked horizontal three inches under the seam ,crack was 10 inches long and had fuel leak though it. I told him it was unrepairable . Your thoughts? Only thing that came to mind was a 14 X 14 patch? thanks

[@OFW]

If it was wore thin I would weld the crack then plate over that. Then pressure check it.

[@Amberhazelton-ih4bu]

What about a water tank?? Me and my better half had a job this weekend and it was our first tank. Not only did the weld crack, we had no idea about a possible explosion!?! Please help!!!

[@OFW]

Welding on a water tank? Should be no issues unless water is getting into your weld. Then it might affect the weld but it won’t explode.

[@davidmerullo551]

why dont you ever wipe the aluminum with IPA or some sort of fast dry anti oil such as acetone?

[@OFW]

I usually use acetone.

[@marksweldingmech.srvcs.9881]

Did you ever try using nitrogen? I was gonna try it on my 6.0 ford oil pan. I used vacuum instead and it worked. I had cut out the bottom of may pan was cracked made a new pc to put in. I’ve been getting quite a few dump truck oil tanks like that due to cracks. Don’t wanna get nabbed by DOT. I’ve been slacking in my video making department with all my repairs lately.

[@marksweldingmech.srvcs.9881]

Oh I always drill holes at ends of cracks

[@marksweldingmech.srvcs.9881]

Ambidextrously good move.

[@OFW]

Technically any gas that is inert and heavier than oxygen would work.

[@TheMichiganshooter]

Could you fill the tank 3/4 full of water and use less gas? P.S. I'm not a welder.

[@OFW]

You can use water but then you spend a bunch of time trying to get all the water out.

[@SuperSecretSquirell]

Let me guess...it's out of a KW. At my last job every single truck we had developed cracks there. The company that repaired them for us would cut the end off and weld in a bracket to stabilize the standpipe to keep it from doing it again.

[@OFW]

It’s off of a Peterbilt, but I believe they are exactly the same

[@SuperSecretSquirell]

@@OFW yup...all PACCAR stuff now.

[@yaykruser]

You should add what you charge your customers. that would be something no other channel does.

[@bensanders2871]

34 years ago a local diesel mechanic welded on a steel fuel tank. Blew the walls out of a 40by 40 steel building. The mechanic die 4 days later from his injuries.

[@OFW]

That’s exactly why I take extra precautions.

[@paulusmarc]

Bon Boulo😀😀👍👍

[@ttargetss]

Didn’t you weld a fuel tank leak on a grader that was full and soaking the area even as you were welding?

[@OFW]

Yes. On a scraper.

[@ttargetss]

@@OFW I’m guessing the same couldn’t be done due to contamination of the weld on aluminum tanks? What’s the basic method? Lay a couple cold tacks to encapsulate the contamination until the leak stops, then clean and run hotter passes on top to seal it up?

[@OFW]

@@ttargetss it could be done with fuel coming out. The weld most likely wouldn’t be as good. this is a better option and since the tank was already removed and drained for me this made the most sense.

[@bigdave6447]

You California boys can afford argon we Eastfcoast boys can't afford such luxuries! Had to repair a gas tank with 5+ gals of gasoline in it . The tank had rotted through under where the mfg 's tag was attached from salt,dirt and water. Ran a piece of exhaust flex pipefrom the welder's exhaust into,the fill port on the tank.started the welder after a minute I ground off the tag cleaned the area,welded on the patch and tacked the mfg.tag back on . N o removing tank or gasoline or argon or gages and unfortunately to some I'm still here to,write about it,!!

[@OFW]

I be you were clenching the whole time. That takes balls welding with gasoline.

[@bigdave6447]

@@OFW no, because exhaust is inert ,can't burn twice,but as a disclaimer I 'll use all you guys saying " That's how I did it not how it should be done! I will say I like your vid's your beautiful equipment, your skill and knowledge, hope you do well always!!!
