Ya if you had a welder with big enough capacity, you made sure all your material was properly cleaned before welding, and you had good clean cut joints that butt up nice and had beveled edges then you'd be fine. Also, you'd have to know how to use the machine. lol

I only suggest making one if you are confident in your welding skills and I take no responsibilities to any injury to yourself whatsoever. lol Just to cover my ass.

But I agree with Joker, the best would be to find a used one if you could. The things never really wear out if they're in a home gym.
