One reason that you would use TIG would be the cosmetics. And, you can get high penetration in THIN material. You can weld almost any thickness to material as long as you know how to do it properly. I, personally, have gotten a tac to run on a piece of copper the thickness of a soda-pop can. But this process take some skill and practice to get.
