Welding a Leaking Tank

[@josecarattini2229]

Thank you very much for your video.I fixed the tank on my sterling truck. Yes, you have to drain the fluid

If you have a tank that has some small cracks and holes in it you don't think that you can just patch the hole with some Weld.? I have a little crack in a tank and the tank is not really rusty I'm hoping I can just Weld the little crack in the little hole not just put a hole piece of steel over it. What do you think?

It depends on if the crack is result of corrosion or stress. If it's rotted around the crack you may be able to fill it with weld, but it won't last very long because it will just continue to rust around the weld and leak again, which is why a patch across the entire corroded area and best for longevity. If it is a stress crack, then a weld may shore up the leak, but you will want to address the reason for the stress as well, which may or may not be part of the repair itself.

Was it full of fluid? Or did you drain it before welding?

I was just drained. Hydraulic oil isn't volatile enough to be concerned about.
