Diesel Tank Findings

- Hey guys. Follow along as I make a typical discovery in these types of tanks. Simple job, one that many people do on the daily. Nothing special here. Enjoy the 1,233 seconds. Bigger jobs to come soon. Thanks for the support.
A friend here in the UK had a small haulage company. Like any business he ended up employing a miserable disgruntled driver at one point. Eventually, that disgruntled driver was sacked.
Anyway, once the driver had gone, the truck he'd been the driver of became very unreliable. The engine would cut out at random and would often start again after a few minutes without actually doing any repairs. That truck almost gave my friend a heart attack due to how much business he lost because of it.
Eventually, my friend had had enough. He set to work one weekend with his mechanic and they stripped the fuel system off completely. Eventually, by swapping parts around from their spares, they discovered it was a fuel tank problem. Sometimes fuel would flow and sometimes it would completely stop flowing from the tank. They shone lights into the tank and nothing could be seen. Even when fuel stopped flowing out nothing could be seen. They put a new tank on and the truck was fine again.
My friend though - he'd gone this far and needed to know why the old tank was broken like that. Like you did here, they sliced the tank open and had a good look...
Seems that the disgruntled driver they'd eventually sacked had placed plastic sheet into the tank. The plastic was the stuff you wrap around cigarette packets that needs to be peeled off before the packet can be opened. (not sure if the US does this but it was a thing in the UK)
Seems that the plastic wrapper in the tank became 'invisible' in diesel fuel and would be sucked to the fuel outlet during the time the truck engine ran. It would block fuel, stop the engine and without suction would release itself again. All of that time it was 'invisible' from inspection.
Great repair on that tank. I'm amazed the baffle broke like that.
Dude, that must have been driving him crazy. Its so hard to see that kind of plastic.
wow now thats devious its like hes done that before
friend of mine was a smoker, yes the US used that cellophane rapper on the cigarette packs.
I have a psycho a hole for a neighbor. And a friend who smokes. How many wrappers for a small SUV???
similar story, but with a ping pong ball, not a cig wrapper.....drove everyone nuts
I bought a cheap boroscope off Amazon and it's quite handy. With one of those, you could have looked into the tank and figured out the problem before doing any cutting. Mine has a little screen with two cameras, so you see straight ahead and 90 degrees off axis. You can also take photos so you can get customer buy-in on a solution. Well worth the under $100 investment.
I entered here to say the same. Thanks for pointing that out first 👍
Some helpful tools can save much time and grievance.
I did the same.. I found one on Amazon for abut $15 that hooks up to your phone via a free App. It also has a 15ft cable and with a small head you can also drop it down a sparkplug hole. Completely waterproof which also makes it handy for sewer lines..:)
I'm amazed how well you filled in the little starting hole. I'd have thought, you'd have cut a little triangle from the baffle, to lay over that hole, to make it easier. But you got it done, and I was all, 'wow'. Nice.
a good trick if you have to use a jig saw on thin metal and you really want to use the whole blade is to double stick tape some spacers (perhaps 1/4" plywood) on the shoe of the saw. As a segment of teeth wear out you can tape on another layer and jump the saw up off the work and get on a set of fresh teeth.
Nah, just fire up the plasma cutter and hope for the best.
@@yatessmyrna No doubt faster, but I dont disagree with his approach. Plasma would be a sloppy wide kerf, tig easy for sure, but your not gonna get a thinner kerf and cleaner than what he did. Bit slower, but smarter in the end in my opinion. Diesel never gonna go boom so whatever floats your boat.
smart idea
@@ICWeld well did it leak ??? with all the starts and stops could not tell if you welded over your 1st bead to start the 2nd ?? a lot of guys will use air ,,, BUT YOU HAVE TOO USE LOW AIR PRESSURE . too high you will pop out the tank and make a ball .or split the tank ..when you get a couple of pounds of air in the tank soap water all the welds ..
Good idea. Ir just lay it over as he did around the baffle. You know, if we can't dazzle'm with knowledge, baffle'm with bull ....
I'm leaving a comment to help out IC's analytics. I Also watch the commercials because he makes more money when I let them play through.
And.... I go full screen because I diggit 😁
Thanks for the support man.
I'll share a life story for fuel cell safety. My friend Mike was at his early days of being a MW (Millwright) working his dad's shop. He was welding a damaged cell all was good till he wanted to make one last stich, he was using an neutralizer spraying inside the tank but for this last weld he neglected to spay the neutralizer. He lived the blast but was never the same guy, every time I see him it still reminds me of what skipping one small detail cost him. This happened over 40 years ago. Stay safe guys.
What fuel was in the tank?
nice repair, watch
Fitzee's Fabrications he does some amazing work , good tips from him. thanks for the video
Have two friends die over non washed tanks with no purge gas. Sorry but don't trust anyone with washing out. Great job.
Thanks for sharing Isaac! True craftsmanship by a sensible welder. Everything worked out perfectly. Very smart keeping your cut to the top area of the tank. It shows what a little forward thinking can do for you.
Nice job. Well done. I'm a retired sheet metal worker / ticketed welder. Personally, I would have started the cut in each direction by blue lining an inch or so, then knock the blue out with a small slot screw-driver, enough to get your jig saw started. That way you don't have any big holes to fill. [Potential site for leaks.] Also, instead of using 0.030 wire, you could keep a small roll of 0.023 wire in the shop for the odd job like this where you could use a lot less heat. [ less warping, and longer beads, meaning fewer starts and stops. Meaning fewer potential leak sites. ] I love your vids. I have welded miles of light gauge galvanized and stainless over the years and I have a lot experience with sort of materials. I'm not trying to upstage you, I can only hope to be half as good as you some day. Just wanted to share a few tricks. Thanks. Rick.
Anyone that questions your skill or method of doing ANYTHING has obviously never seen one of your videos. I’ve got 15 years of experience at 34 years old I’m pretty seasoned, and Ive learned so much from you doing heavy equipment repairs that I feel like I should be paying you lol you are so much more than a tradesman you’re a damn artist! Especially with a torch!
Looks thick enough that you could weld 1/2 lengths at a time. Do it all the time. The trick is to start the weld, flick it like a match at the end which lengthens the arc and moves it quickly to distribute the heat to not burn through
And fyi, if you ever need to weld like that again, a couple copper flat bars laying 1/8” beside it works very well to pull the heat out of it and not burn through as much.
All the start and stops will be the spots where it will be cold and not fuse enough to the base metal and there will be a crack type of weeping leak
Been welding for years and years. I can weld the thin stuff, but learned more by watching today, thanks for the way you do your vids! Kudos!
I got a barrel for 3 bucks from a guy on the roadside. It said solvent and really stunk. I wanted it for a wood stove in my shop. The ends were solid and no way to relieve the fumes. So I used a saw like that. That same Saturday another guy a mile away had bought one like it and was doing the same thing. The news reported that he used a cutting torch and it blew out the garage and damaged the house. It killed the poor guy. It freaked me out so that I used soap and water to wash it out before I welded on it.
You would be one fine teacher to help guys learn about welding. A vocational school would be lucky to have you.
a vocational school is a place for tradesman to retire as they do not pay industry wages. my teachers at vocational school chose to do so as a retirement option to stay busy and loved to teach. a few other teachers chose to teach for family reasons. its a great benefit to hire old timers with decades of experience who enjoy passing on knowledge.
Seems like this would be perfect for a TiG or an actual gas torch weld. Guess no one welds that way anymore, shame. You can lay dimes down that are flush with the top of the metal, very little grinding needed, unless you don't want to see the dimes. Also allows you to weld in 2 inch strips and yes, both from side to side to prevent the warping.
As usual though, you did a superb job. Sometimes, you do have to go outside your comfort zone. Cheers :)
Fuel/ air ratio is the key to combustion. If you take a handful of dry grain in a pan and hold a torch to it it will burn once it gets hot enough but if you take away the heat source it will probably die down. We would never consider grain to be explosive. However if you stir up grain dust so it mixes with atmosphere, say in a large metal or concrete tube and provide a source of ignition it will explode like gasoline. Very powerful. You were completely right to be cautious with diesel. With the right fuel/ air mixture it will blow up. Any substance that contains carbon and hydrogen can become a powerful explosive weather it be a hydrocarbon or a carbohydrate.
So will flower, dry non-dairy creamer even some of the sugar substitutes, lint, list go's on and on
Once wile I was working on pre wash blue jean factory a kid helping us, thought it would be neet to take air hose and blow some lint off the purling wile I was welding on the rafter and it flashed.
Now I was welding on the bottom of it and the and the purling was 18 to 24" from where i was welding
flower will bondo dust will sawdust will.. even metal shavings will ignite ..
Hey Issac, my wife just picked out a movie to watch. Private Affair. Corny Italian movie, poorly dubbed in English but!!, They feature a Hudson Hornet! Red!:) I can't help but think of you!
So many critics.. "did you clean out the tank after all of that welding?!"
Don't worry about it RUclips comment, are you getting paid for this?!?
I can tell by your comments that you must get quite a lot of arm chair criticism. EVERYONE has their own way of doing things and I for one can appreciate that!!! Rock on!!!
Nice work Isaac, thin stuff isn't my wheelhouse either but if you take your time and have a good plan you can get er glued........like you say it's only metal right 🤣!
Love the sense of humor that IC shares. IC said "this thing ain't winning any beauty contest." Had to laugh, thanx for the video and sharing some good humor. After welding, how do you test a tank for leaks.?🙂
Could you have filled the tank with say water to reduce the explosive gas component? Just thinking what my dad would have done. Love this channel. Always thought provoking.
I also do heavy welding but keep a 10lb spool of .023/.024 wire on hand for those last minute “please help jobs.
A trick I use when doing any repairs on anything that’s had any sort of petroleum in it is rinse it thoroughly with dawn dish soap and water. Only dawn, it’ll neutralize the petroleum left behind making it safe to repair.
Next time try .023 wire,I use it in the body shop,I weld 18,20,22 gauge metal with it,all of these are thinner than that metal that tanks made from.
G’day sometimes I have used a hacksaw blade 32tpi and ground it to fit my jigsaw when I cut thin stuff
Sheet metal wise it looked pretty good. But a continuous weld which wasn’t really pissibly would have made me feel better about it being and remaining leak right in my mind. I don’t know if you could have done better with it taking far longer with TIG or it you could turn your MIG down and run a continuous weld bead around it after you had stitched it closed.
HI I always wash the tank with a little dish soap and water dry it out, then fill the tank with welding gas before I start welding, I don't know if you did that or not. explosions suck!
Good luck Rich
I see some comments on using soap and water to dissipate fumes making a tank to weld on. I used to pull and resell auto fuel tanks. Had an order for an old GM El Dorado tank- very odd ball. I finally located one, it had a broken baffle inside (steel… most were plastic). I drained the tank, mopped out the fuel, stuck a garden hose in and let it pour water out for ten minutes. Drained it, mopped out the water. Went to heat the area up where the repair was to be and the thing went off like a h bomb. Ballooned the tank, gave me third degree burns, moved the truck the tank was leaning against. Apparently the water only helped the vapors. Since then, Ive heard to use a flex pipe connected to a running car exhaust to pump co2 into the tank to prevent a blow up. I just want to caution anyone trying the water and soap method. I didn’t use soap but I don’t see that would have affected the outcome.
I think those small hole saws were originally developed for cutting spot welds on body panels. We’ve been using them in bodywork for years and they work great. I usually take a punch and make a divot in the center of the spot weld so it won’t walk around.
Yup, I used a center punch to keep it from walking around.😁👍
I usually tig weld fuel tanks as the mig will throw spatter balls inside the tank which can cause pickup and or rust issues in the future. Diesel is usually only explosive under pressure so i always weld with the cap open. The need for purging is not usually required. but in saying that you never know what has been in the tank or if they have added any additives to the fuel so purging will eliminate any dangers that may be present. Always degas petrol and chemical tanks. Also a good idea to pressure test your welds on fuel tanks.
That is something you understand that you 're Australian counterpart doesn't. Cutting speed!
Most people don't know variable speed means. They think they have to run everything wide open.
Black paint can fix a lot of things. Just guarantee it won’t leak as long a site never tipped. Lol😂
Bleeding is leaving a DNA sample just to give future historians something to discuss. Contact tracing to catalog all your projects.
Too much wire stickout for non structural wire-unless you were doing it to prevent burn thru. Nice job.
Sorry to say this but diesel in the right situation is as deadly as any other combustible fuel. A lot of people don’t know that linseed oil is highly combustible?
Hello ICWeld I found your comment about comfort zone due your usual work media being heavy plate very appropriate. It is always good to keep practicing as many different disciplines you can to keep your basic skill levels current. Too often in the real work environment we loose profiency due to repetitive type work. Keep the interesting videos coming.
You answered your own complaint. Wheel the area before you cut.🤣
I approve 😎 sheet metal = 3/16" plate 😁 everything else is a fish can 😄 even the spam has netter rigidity!
I’m not sure how small of a tip nibbler you can get. But they chew threw sheet metal 3-4 times as fast and last.
I use the same hole cutters. They work great on thinner metals, use the same technique, jig saw. Gives a thinner kerf for rewarding. Great job as usual.
What brand are those hole cutters? I am an electrician and use sutton hole saws, they arn't great at cutting thin distribution board gland holes.
Sorry for the late reply. Mine are Blare roto cuts, I believe. If memory serves me right, got this on Amazon. I have 2 sets.1/4 to 3/4. Second set goes too 1 1/2 I think. They make them bigger. Clean cut, no bur.
@@kirkrichardson4443 Thanks mate appreciate it!
if you do the welding going forward and much better you always have the material that tends to close the job
Don't forget too pressure test for leaks......
there is always a leak....lol
I would have cut that baffle into strips for a backer and just welded it out. Yes it would have been rippled when done however done way faster and less likely to have a leak
A tip I learned a while ago. If you need to pressurized a tank like that to check for leaks you can cut an inner tube around the valve stem large enough that you can place it over the filler tube and use a hose clamp to secure it then you can air it up.
I watched some Indian metal workers use a chisel and hammer to cut open diesel tanks, much like you open a can, was quite fast and no loss of material.
You are really good. I wished I could weld like you. Delbert Texas
Big - Small - I C Weld - Does It All
(Burma Shave)
In Pakistan they do that whit stick welder. Now they have moist sticks :(
I hate fuel tanks. I usually just always plan on autogenous TIG flow over the top otherwise they are tough to seal.
As a Bodyman You did Great. That metal was a little thicker than most body panels. So your method was sound. no major warpage, if any. Well done.
I useualy end up mixing my blood with the steel to0 , so don't feel bad.
You need a nibbler that chews through steel, I use them for cutting thicker roofing iron
Tanks are like guns, when someone gives you one, ... Its loaded. I admire your work.
Na, If you pull the trigger and kill some one you are aiming at, it is someone else's fault. Ask Alex Baldwin.
My cousin had a bad experience welding a gas tank for a friends Opel. He filled it with water and let the hose run for a long time. He left water in the tank and started welding and it went down without a problem. 10 minutes later he went for a coffee break and came back 15 minutes later and continued welding and BOOM! Somehow it was still leftover fumes that had accumulated in the tank while he was on his coffee break skimming the surface of the water. The tank flew straight up and hit the ceiling of the workshop knocking his welding helmet off his head. I was a few meters away welding a crack in a truck frame and almost had a heart attack.
@@nameofthegame9664 I had a tank I had to repair. Was reading up on how to do it safe. Came across a story similar to that. Guy had washed it out as best he could then filled the tank for like a week and when he went to weld it it blew up. Conclusion he came to was you can't clean out gas fumes from the metal, they are in the pores. Another guy above says Dawn will do it. If you search the internet you will find a million stories of guys blowing up tanks that they thought were cleaned out. Running engine exhaust (used to be the Military's S.O.P for WW2 I read), dry ice or an argon purge seems the better way to do it. I ended up looking up the price of a new tank and decided 100 bucks wasn't worth the risk. If I ever have to do it in the future I will use a tank of inert gas.
Vertical down when set up proper can be a good procedure for applications like that
use a little Soapy solution as a lubricant saw your blade all your hole saw doesn’t get dull
Thank you Isaac. I learn new things from every one of your progects.
I just pump the tank full of co2 to keep explosions down.
Looks fine to me Great Vid👍👍👍👍👍👍🥽🥽🥽🥽😎😎🐓🐓
You might make picture frame around and weld them
Thin metal.... It's a bitch! 😂
Welding on anything combustible is VERY DANGEROUS... i remember in 1973 at 16 yrs old...i was helping the heating guy at the lake...we had cleaned a furnace at the Septic guy's house... stopped in his 2 bay shop he parks his septic truck inside....it had a wall separating the shop ( as he heats only one bay in our extreme cold winters in Canada ).. the shop keeps his septic tank from freezing up overnight...it had wood studs and drywall on one side ( drywall on the side of unheated bay )... it had a big damaged section of drywall between 2 studs...i asked what happened to that wall...he said was repairing his septic tank ( welding something along the side where this hole was and between the truck and wall )... he said when he woke up...in the unheated bay side.... dazed and confused...and really SORE...he stumbled out to house....not sure what happened still...went inside..got his wife and they called the ambulance / fire dept.... when the ambulance / fire dept ( volunteers out there ) arrived...they asked " What happened ? " as he was confused still and dirty from dust and debris on his overalls and his wife had taken the welding gloves and welding jacket off him and threw them on the floor..... " I was welding on the Truck..I think...."?? They went outside and saw the Wall...and hole about his size between 2 studs.... it had blown him through the wall...his welding helmet was in the bay he landed in...the welding cables from arc welder too were laying through the wall...luckily he missed the studs ( non load bearing wall so 24 " apart ) and just went backwards through the drywall...... he was Pretty sore still months later ( summer time when it happened and fall now )... he had no major injuries Luckily but still had back and aches and pains in many places... but was unable to work for months.... and he realized Methane is very Flammable when ignited.... and extremely glad he only put drywall on one side... and glad he wore a heavy welding jacket and had gloves on and proper overalls and workboots too... all of which helped him to lessen the injuries... i think he did have some internal injuries too...and cracked ribs?? it was long ago and i just remembered it watching this video....
Wow, thats terrible. I always worry about those types of things as well.
you know what they say, trust, but verify what every you are told.
Another great job, but how about a credit for your poor pooch, who found the coolest part of the shop?
A small tip, if when you get done mig welding and you are still concerned about pinholes or bubbles in the weld, you can then run a tig welder over it to smooth it out and "melt" the imperfections away.
Running tig over mig to correct pororsity in my experience would tend to make it worse. Maybe it has been because I've tried to use filler rod or because I didn't grind it thoroughly enough, but any pin hole when you're just using tig is difficult to correct. Gas tanks can be a frustrating battle just to weld even a simple bung sometimes when you end up with a pin hole leak. I'd be resorting to bronze over the spot when I get desperate. What's your trick?
@@donaldduncan1374 I don't use a filler rod, just make the molten puddle and let the bubbles come to the surface.
6011 electrodes work the best
@@meshaft Thanks for that tip. I guess I was always too impatient every time I tried to correct one. I was doing a few tanks years ago and only know that I had problems with pin holes.
Bosch blades the teeth per inch are in the part number.
That looks like T118 (18 TPI) on my phone
Yeah, thanks man. I noticed that as I was editing the video but it was too late,😕😕😕😁😁
@@ICWeld You really are willing to take anything on. It's commendable!
Another excellent repair! 👍
She’s not gonna win any beauty contests. 😂
I think it turned out great though. ✌️👍
Was a bit baffled there for a while, around the 5 min mark
I liked it you are someone good. Delbert Texas
Why didn't you tig weld it you can control the heat better with tig and i thought you had a tig
You don't thank us for watching, Isaac, although the courtesy is appreciated; we thank you for sharing your skills with the style of a good teacher. Thanks for the jigsaw blade tip.
👍👍Great Job.
I picked up an inexpensive air-powered reciprocating body saw not long ago and I love it for thin metal like that. Great explanation of your process, and awesome work, as usual.
Im one of those kids guilty of 100 mph
Just to add a thought, you could have ran a magnet all around the inside of the tank to pick up all the bits of metal from the jig-saw. Rick.
I keep a roll of .024 on hand for this kind of thing.
It used to be said that to have 3 teeth for the thickness of the metal was good.
I like .023 wire for thin sheet metal like that.
I the body shop, we used to use soaking wet rags to help reduce warping when we welded in patch panels. Worked well overall.
Definately learned something.
You should have washed the inside of the tank before working on it, instead of relying on others telling you they washed the inside. I know its diesel and not as combustible as gas or fuel, but still you want to live to keep working safely. You read and see so many horror stories of guys dying or getting deformed welding on used tanks. Im not saying stop the fuel repairs, just be a bit more careful so you stay safe. At the end its not worth the risk for your family.
Thanks for the reply but it tells me you didnt watch the whole video. I have a small clip of me washing the inside of the tank. 😃😃😃😃😃😁😁
i remember when i joined your channel at like 5k subscrubers, love the content and happy to see the growth!
Thanks so much
I have loaded the stop and go into my memory bank.
Welding thin metal will teach you patience lol
I used to work with shipyard and construction welders their welds looked awful but when x-rayed were perfect, comes from years of welding 8 hours a day, proper prep, alistair123 is another great welder funny and droll loves his job
Only thing I would have done different, grind all the crap off before cutting. Makes it easy over a flat surface vs a cut surface and keeps the blade from fouling as much.
What did he say on the subject?
Nice one Isaac! I like it 3/16 is sheet metal!! 😜
How are your oxygen and acetylene welding skills? Some of the older guys I worked with when I first got into working on equipment were awesome in that. They welded sheet metal and it looked amazing.
I have heard that oxy-acetlyne is the best way to weld thin metal. The flame pre-heats the part that you are welding next and it is less heat than TIG.
They dont even teach the young kids that anymore where im from.
That looked like it was made for Tig??
Always place some magnets inside
75/25 is OK exhaust gas is cheaper!
Light weight material. I have a tank that's 3/16".
That cutter is good for cutting out spot welds to
"Tanks" for the video... 🙂
Yup, if you don't have a tig and or time that is the way to do it.
I meant to say to you before I heatsink never thought of using a heatsink.
Isaac, there are sets or individual cutters on eBay or Amazon of TCT carbide cutters for just about any metal drilling you might encounter. They are made of Chineesium, but I've seen very good results from them. I have my second set now. The first one is now at home at a local maker space.
Have you ever played with flame straightening?
I've added curves to metal tubing with heat but not straightening to say.
