Short answer yes. Depends on the guy doing the welding. The cybernazis will immediately appear and cry out.

No. There's a hole for a reason- lack of maintenance leading to corrosion and thinning of metal. Those small compressors are cheep enough to replace that it's not worth the risk. It will hurt anyone in the vicinity if there is a catastrophic failure under pressure.

Just one example of catastrophic failure

Shorter answer is no. Scrap the tank. As Metal shows, not worth the risk.
And no we are not nazi's. If you want to take a chance with that tank then I will introduce you to Darwin.

That hole looks like a puncture, not a rust hole. If so, weld it up.

Yes it does but is the OP certified welding pressure vessels? Not something I would to do if you ask me. I wouldn't trust a DIY repair on that

Weld it up and use pvc pipe. It'll be fine.

Speaking from experience if you weld it more pin holes will open up as you use it. Inside your tank is likely rusted badly all around that area. I wouldn’t be worried about the tank exploding etc and if you just want it to last to finish a job it give it a shot.

I've seen people try to weld tanks, and more pinholes pop-up... They are also time-bombs and not worth risking your life to try and save $100...
There was a guy on youtube that cut apart a tank and basically the water condensation eroded 'channels' inside towards the draincock... It was shocking how thin the metal was and how much was eroded away!
Always drain your tank!!!

I replaced mine.
But I did 'repair' it for a short term until I could replace it.
My repair consisted of a stainless steel bolt and jb weld. I drilled the hole out larger so that it was clean. Tapped it. And then screwed a short bolt in with jb weld all over the threads.
While I was putting in the patch, I noticed that there were two other bolts already in the bottom of the tank. I called my dad and asked him about them. He said they were in the tank when he got the compressor. He originally got that compressor from my grandfather before I was born... That's dang near 40 years of that compressor's life chugging along with a bolt in the bottom of the tank.
I ended up getting a new compressor, but still have the old one. I hope to put it on a new tank at some point as a portable setup. Thinking of mounting a small 5 gallon tank onto a dolly with the compressor mounted above it.

Is it worth risking your your life and property for only $99?

Tanks explode catastrophically because they're over-pressurized.
Tanks that rust, get pinhole(s) that leak, not explode.
Yes, you need a new tank. You may not need it RIGHT THIS MINUTE. Make a temporary repair while you look for a new tank or new compressor.

Oh, you could not more wrong than with that statement right there.
Father in law had a 60 gallon standup on his farm that he did not drain on a regular basis. When the bottom let go it damned neat went through the garage roof. Busted a few purlins and dented the roofs metal but didn't quite breach it. Blew a very nice circle out of the bottom of the tank. So yes, they can definitely explode if rusted.

Remove the motor/compressor from the tank, I'll buy them. I've got a great tank but the Chinese POS compressor locked up, broke the con rod, then melted the belt and let the motor run for god knows how long until I noticed it when I made it back out to my shop.
Harbor Freight, can't get parts to repair them.

Personally, I wouldn't mess around with it. I would just get a different compressor.

X2. It certainly would be cheaper to replace the compressor than to have the receiver repaired and recertified. I doubt replacing the receiver would be worth it, either.

My experience repairing an air tank...
Years ago my grandpa gave me a small 20 gallon Dayton air compressor that ran good but had the infamous pin hole.
I needed this to work. So, instead of welding up the hole, I cut a patch to cover the thin area.
I did a nice job on it and it had nice looking welds. So I plugged it in and started building air. I watched the gauge as it climbed. It hit a hundred lbs, so I thought it was going good. So it hit 115 and boooooooommmmmmmbbbbbbbbb! It blew the wheels off and one hit me in the shin ouch! Scared The beejezzus out of me! I was very surprised that thus happened, since I have welded up Rusty semi truck air tanks before, and successfully. So against my judgement, NO do not weld one up. I have however used self tapper screws, or pipe plugs with JB weld to fix similar problems with success. Be careful!
