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.

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.
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 .
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!

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.
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
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 😄😃
I had to purge a 10,000 gallon gasoline tank to saw a hole big enough to shovle out the sludge. We used CO.2 I ran 2 200cu ft tanks then a 150 tank then sweated my but off
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!!!
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.
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.
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 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!!!
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?
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
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.
@@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?
@@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.
So your "test" for argon... yes a flame will go out in argon, but what if the tank WASN'T fully purged yet... putting a flame to gasoline vapours coming out of a tank that may not have been purged of oxygen may not have been the best approach...
Wouldn't the diamond wheel get gummed up with aluminum? Love the videos btw they're always entertaining and informative Edit: Nvm yeah it's the safer option
Love you stacks of coins. Aluminum can be difficult but you make it look absolutely beautiful and easy. Love his channel Greg.

You can get a Lincoln tombstone stick welder for 100$ used. I would recommend if you’re considering it

diesel exhaust is the best. used that a few times to weld up a gas tank.
I loved my job shop days. You’re doing good work.

Another spot on repair :-D
A dog is a good friend, it will never judge you and always be happy to see you.
Lovely animals.
Cats on the other hand lol.
You can weld either handed. That’s a skill I taught myself too. Be handicapped only welding one handed.
Nice job !
Thank you!!
Good job 👍
Cool trick about the match! I also weld and have a shop and mobile rig.
That is some seriously badass weld puddling. Gorgeous welds.
bought a new synchrowave 250 in 79 or so. 2K. big as a jukebox.
Cool video! Thanks for sharing! 👌👍
Thanks for showing/explaining the purge technique. Just curious how long that took to purge.
Probably about 5 minutes. But I let it go for 15 minutes.
Great work. If there is reincarnation, i want to come back as your dog.
Great job as always
I come here for the welding and fabricating but I stay for the science.😄
stacked dimes - great weld
Nice job!
Have you ever tried tungsten wheels in doing that type of work I have found it very successful very quiet and Clean. Michael

I use Dry Ice (carbon dioxide) , much cheaper than Argon and I can get it at my local Publix super market.

good vid. About how long did it tank for the argon to purge the tank?
About 4 minutes. But I like to make sure
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!!!
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.
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.
That’s exactly why I take extra precautions.
YOU DO GREAT WORK ‼️ Vinny 🇺🇸
You should add what you charge your customers. that would be something no other channel does.
I thought about that, but out of respect for my customers I do not want to share prices.
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.
It’s off of a Peterbilt, but I believe they are exactly the same
@@OFW yup...all PACCAR stuff now.
Nice work. Can the purge like that also be used on a gasoline tank that is steel or aluminum?
Probably, but I will not ever weld on gasoline or propane tanks. It’s not worth the risk.

Correct.
Good job! What is the price range?I have the same issue with my fuel tank and just want to have an idea so I don’t get ripped off! Thanks.
I think I charged about $300
Well, if you do the flame test to early it might do exactly what you try to prevent...💥
Not with diesel.
Do you think the original weld was too hot-leaving that line where the crack was? Nice bullet proof repair brother!
Could be. They seem to flex in that area too.
👍
why dont you ever wipe the aluminum with IPA or some sort of fast dry anti oil such as acetone?
I usually use acetone.
good info thanks
🎉
Could you fill the tank 3/4 full of water and use less gas? P.S. I'm not a welder.
You can use water but then you spend a bunch of time trying to get all the water out.
Bon Boulo😀😀👍👍
You said 10 c.f.m, I think you meant c.f . h only because a T bottle of argon holds 330 cubic ft and @10 cfm it would be empty in 30 mins..

Coffees on!! ;-)!!!

If it was wore thin I would weld the crack then plate over that. Then pressure check it.
Sweet !
bro, why not just remove the fill cap so nothing can combust?
Because I am comfortable with the way I did it. Even with the cap off something can still happen.
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.

Oh I always drill holes at ends of cracks
Ambidextrously good move.
Technically any gas that is inert and heavier than oxygen would work.

Yes. On a scraper.

oGreg...f course, you know you can drop dry ice in the tank......but argon is quicker,,,,,,but when your Ar is Gone, it is time to get more...
I know but I have always used argon and I feel safer that way.

Tank sealer cheaper easier safer...
