Broken Fuel Tank

I wanna know what college has a welding teacher?? is there also a wood shop and metal shop teacher??? or is this an ITT tech jr college type thing??

Depending on where you live, there are Vo-tech schools offering courses.. However...ALL that I have meet and used / hired where trained at Union Trade , Sponsored Schools .. Mostly Pipe-fitters schools a few Millwrights and fewer yet IBEW schools. All Have schools who specialize in this training at a Certifiable Level..

Your KILLING ME !! Hahahaha

I am a bit too young - wasn't around when that happened.

Divcoz? (OK, you have been stating recently how old you are).

University of Maryland College Park - Engineering

I took a welding and foundry course and also a pretty good woodworking course (learned about actually using handplanes and chisels vs power tools for everything)

I've done a lot of welding of plastics, but I don't have a fancy rig. I just use my handy-dandy Weller soldering gun and the special paddle-shaped 'smoothing' tip (#6160)... for the 'solder' you can use whatever thermo-plastic material that comes to hand... milk bottles work in a pinch, but old plastic bumpers cut into strips work better since they are thicker. Heat up the flat tip and you can easily weld plastics up to 1/4" thick. The paddle-shaped tip helps to make your end result very smooth and tidy, and the thinness of the tip allows you to penetrate deep into crevices to get a deep weld.

I used to use a soldering iron also - amazing the difference the right tool makes. Now I have adjustable temperature to match the plastic I am working, the ability to feed melted fill material into the area I am heating, a wide selection of repair materials and colors to match the wide variety of plastics items are made of today, and a wide foot to make the repair more attractive. I can not imagine using a soldering iron to repair the front bumper cover on my car and have it last. I also do not see how I could press stainless steel screen into the area to be repaired with such a small tip as on a soldering iron. (This trick using screen has resulted int the repairs where used never failing yet.)

To each his own but this little investment has paid for itself many times over.

I have a pinhole in a fuel tank I was thinking of patching with adhesive...I think now you guys have put me on to a new skill to try...

[raycarlson]

please don't take that prior posters advice about filling the tank full of fuel, thats not correct or reasonable advixe. thats more old barnyard wives tale advise that sometimes florishes on this board.

These tanks are made of polyethelene - it is pretty immune from the effects of any adhesive. Best/only way is to thermally weld. And yes, a pinhole can be repaired with a Weller soldering iron if you are careful with the heat. I would recommend you pay attention to getting good melt penetration - thus my method of pushing the hot iron deep and then smoothing over.

BTW, my free replacement tank is on the way from Moeller

As that "prior poster', it is not a wives tale - just a method some welders from a previous era practiced and lived through - I am not recommending it. Another point of view is that you should never weld fuel tanks because steel is actually very porous and the fuel will actually soak into the steel and make welding very interesting.

Yeah and any rusted areas no matter how lite contain fuel and oxygen which = BOOM

I was going to fill them with some left over borane I have in the shed.

Are you intending to repair or make a bonfire?

[Québec 1]

I had a broken fuel tank and
I bought a new one.

Generally plain ole water is the standard filler for tanks requiring welding that previously contained a flamable substance, at least by most welders who are alive and still in bussiness that is
