Fuel tank in my boat sprung a hole. It is made of 5052. All I had was 5356 filler, and that is what I used to close it back up. Is that an ok filler to use, or is there a 5052 filler rod I should have used? It is TIG. And don't worry, the tank was cleaned out very well before I got going, although I still was a little hesitant when I first started the torch. Thanks, Nick.
Reply:You will be fine with that, No problems.Not sure what precautions you took but if you ever do it again the safest way to weld on gasoline tanks is to run a hose from the exahust on your car into the tank for about an hour and keep it running while you weld. You may already know this or a better way. I just run into people all the time that say you can fill it up with water and this is not the safe way to go.Yes I can tack it for you. I know that won't hold but that is what you asked me to do. Millermatic 350P XR Aluma-Pro push/pullMillermatic 185/spool gunMiller Dialarc 250 HF Water cooledThermal Dynamics Plasma
Reply:Another good trick for welding up gas tanks is to drop a peice of dry ice into the tank. We live close to a ice plant, so it is easy to get...and works great. Haven't blown up the garage yet....
Reply:So what exactly do both of these things accomplish other than preventing explosion?
Reply:That is all they do. I will say, one explosion, is one to many.
Reply:Nick,You didnt just pour the gas out and weld, did you?! You're scaring me, man! Maybe you didnt say that, but....This is a good place to point out that even a dry tank can 'splode. One of my childhood friends, while working with his dad restoring a old chevy truck, blew up the gas tank that had been sitting empty and open for days. A big chunk of the tank hit his arm and then his arm hit his head, blinding him in his right eye, ruining his arm, and left him with substantial brain damage. Fuel tanks are probably the most hazardous thing weldors come into contact with...outside of other weldors, that is. Inert or oxygen-displacing gas pumped into a well-cleaned tank is the minimum safety level for tank welding/cutting.Dang, I sound like my dad. Nick, just be careful. Tanks are dangerous.Last edited by smithboy; 09-27-2005 at 04:18 PM.Smithboy...if it ain't broke, you ain't tryin'.
Reply:If the Oxygen is out of the tank it will not explode. Dry ice is a method for removing the oxygen and so is the exhaust gas in the tank. You could also purge the tank with N2.
Reply:I don't care what you clean them with, I won't weld gas tanks. Once, in my youth, I had a gas tank on the ground with one foot holding it down to close the seam I was going to weld. I had cleaned it with hot soapy water and also had exhaust gas going into it. Anyways, I dropped my hood and struck an arc. Well tried to anyway, cuz the tank was now 10 ft. away and going fast. Scared the crap outta me! Large noise, larger crack, and a lifelong fear. .......Diesel, no prob........Gas, get somebody else.
Reply:TEKHow long had you run the exahust into the tank before you started welding? This does displace the oxygen but aslo and just as important if you run it for an hour before welding this will also boil the gas vapors out of the pores of the metal. This is what blows up. If you start welding to soon BOOM. But it may all be luck, I have welded hundreds of tanks with no problem yet.Just wondering.Yes I can tack it for you.

Reply:got alum, that had to have been 35 yrs ago , and the details are a bit hazy, but I'm bettin' it wernt long enough!!!......... and I'm kinda kidding about not welding tanks because I have done some since, just have a very healthy respect for them and batteries and take precautions when I work around them
