Most (if not all) NASCAR chassis are MIG welded. A quality MIG weld is more than strong enough for roll cage work as well as suspension components. I've seen my share of crappy TIG welds in offroad racing. Multiple pass welds where the root pass is cold and fills gaps in poorly notched/fitted tube and then a "sic Bro weave" washed over the top. Total crap strength wise, but looks like a million bucks.
