Not if you use 400 series SS. It will not rust.
I have welded this material hundreds of times. I would not use flux core wire, but if you have a mig welder with a gas mix, grab some 400 series SS from Ebay, weld it up, and forget about it. You will never have a problem. I would not even worry about painting it unless you want it to look pretty.
I welded baffles in my tank a few years ago. Washed it out with soapy water (Dawn dishwashing liquid), then welded away. I had no problems whatsoever.
