Welding on a Fuel Tank

[WIDESIDE72]

My dad is 74 yo and been a welder for about 50. He has also used this technique for welding ga and diesel tanks. He suggested "flashing" the gas that is being exhausted before starting the weld to be sure that it is not combustible. He either takes a lit cutting torch and holds it out in the streanm of exhaust coming out of the tank or strikes his first arc near the exhaust. he uses argon if available.

@WIDESIDE72 Thank you so much for your comment. I'll pass the info onto my husband.

We've used a CO2 fire extinguisher to purge the fuel tank prior to welding.

Exhaust is not inert.

what a tard... exhaust fumes are a horible idea

What? Can't weld in the rain phsss that's all silly talk I weld in the rain all the time. Plus it would be perfect for this video.

This isn't worth the risk, so stop doing it. Your insurance company would have a field day with this should it take out the garage/house/operator. It isn't cute, it isn't cool, and even if you backpurge with inert gas, it's still high risk.

Ask husband to post this on a WELDING FORUM instead of Youtube and see what comments he gets!

Charging a bit more to do things SAFELY, like clean out the tank with non-flammable means, blow it dry, THEN backpurge it, is the right thing to do.

Mayby you should mention that if your vehicle is running rich. There will be un burned fuel pumped in the tank and ....well... um ... He wont have to worry about doing jobs any more...... except organ donor...

@fitthefeck I've heard dry ice works well to flush O2 from the tank.

Good video,your husband probably has a big heart and likes to help other folks,sometimes these people are few and far between,thanks joe.

[stickmanwelding]

the problem is the car can be running rich and ad more gas fumes to the tank. people die from this, its like a lotto if you feel luck play russian rollete go for it. there is ways to do it right and live. diesel can expoled like the rest of them heat it and vaporize it and see (ie welding heat)

[ecoli2345]

DO NOT DO THIS! I know someone who died thinking car exhaust gas is inert, IT ISN'T!! This video should be removed before someone dies trying this.

[AnneMarie96]

It's a diesel tank. . If it was gas tank my husband would put water in it. Since this video, he has done this many more times. So far, God Willing, all is well.

[TheBeersCold]

Hello Anne, I have also done this several times but I fill the tank with argon gas if it's aluminum. If it's a steel or stainless tank I'll fill it with 75/25 mix gas. It not only crowds the oxygen out, it makes it weld better. I also have the problem of not charging enough for the jobs I do. Must be a welding thing, or the challenge is the pay. Who knows.

[AnneMarie96]

Thank you so much for your comment and watching. "Poor" welders unite! :)

[ekajlewis]

Thats great, I was also thinking of filling the tank with water since I have a 5 gallon tank to do.

Thanks for the post

[AnneMarie96]

Thank you so much for the info. I tried to find info on internet and got no where. I worry when my husband is doing this stuff.

[ansonivan]

Thanks for the tip folks, I'll be using this technique to add a sump to an 11 gallon fuel tank later today.

[AnneMarie96]

Hope all goes well. So far so good for us. No explosions yet.

[AnneMarie96]

Well, stay tuned. We are going to try this again later today.

"Don't do this a home. Actually, don't do this."...hahahaha I think I'll take your advice and NOT do that...ever! LOL
