Propane tank?

Get a professional to do this.

It has a pressure relief if the pressure gets too high, but they rarely vent, I grew up with a1000 gallon one in my driveway in SW Oklahoma where the temps are in the low 100s much of the summer, never popped off. The tanks are designed to hold several hundred pounds of pressure or more. When I did firefighter training, we would put a blowtorch underneath a 250 gallon tank and it would take several minutes each time to "pop off" even with the direct flame. Though it would then put up a huge, hot flame about 40 feet in the air-cool! This was a certified training event, with fully qualified trainers doing the training by the way--and we were all in full protective gear. That said, my face mask melted a bit. Certainly don't try heating up a propane tank yourself!

I know you are just playing with this question. # 1 you will blow yourself up if you try to weld a propane tank. # 2 The gas company will never fill it again if you do weld it. # 3 If it actually did need repaired or replaced, the gas company would condem the tank and shut your gas off immediately until the tank was replaced.

So just incase you're not playing, call the gas company and have them inspect the tank. They will deffinately NOT tell you to have it welded.

Sounds like a hospital bed should be in order if this thought persists! Electric welding is electric flame and will ignite Any fumes or inflamable substances, same as acetylene torch Get a professional to verify this. Then buy a new tank!

first of all are you stupid or easily led , NEVER EVER TRY AND WELD A PROPANE TANK , i take it your talking about a bulk tank in your garden as you dont own it its not your problem whoever told you to this is even more stupid than you or just pure bad youll blow yourself up and probably 2 or 3 houses along with you , get in touch with your propane supplier and they will do a safety check on your tank , when you pay your gas bill along with the litreage used you pay a rental , so not your tank , its there tank so def dont touch it .

OH MY GOD ! you don't weld a propane tank. REPLACE IT! If you purchased propane from a company you call them and show them the problem. they will replace it if need to other wise if its a Bar B Q tank you need go to wal mart & buy a new one along with anything else you need. If you think you can't handle this project get someone that can. Your joking right? Good Luck!

If you have to ask these questions, you should not attempt to weld it.

Yes, if your house has enough amps when you can use it to weld... your dryer circuit might have enough.

You have to evacuate the tank to ensure there is absolutely NO gas in it... you need to take the top valve off as well.

But if you dont already know all this... you should not be doing it yourself.

DO YOU HAVE A DEATH WISH....... all welding can blow that tank...electric uses an arc <that is a electric spark like the spark that runs your car.... hmmm and that spark ignites....GAS......HMMM> to weld two pieces together..... call your gas company or make sure your LIFE INSURANCE IS PAID UP...... don't try it.... you WILL DIE A PAIN FULL DEATH TRYING

weld nothing,buy another,or get blown-up

Seriously, man, I can see this story leading on the evening newscast. I'm not sure this is something you want to try.

i am a l.p.g gas fitter DO NOT PLAY WITH THE TANK AT ANY TIME call your suppler in to do a safety check OK
