Krabysniper, TIG welding produces more heat that MIG does. It's basicly oxy/acetylene gas welding with an electric arc flame. This is why you do not get any spatter like you mentioned. Just the same as if you are oxy/acetylene gas welding (no spatter). It's not to say that a good TIG welder couldn't control warpage it's just not easier than MIG. Before I purchased my MIG & TIG welders years ago I used a oxy/acetylene welder on all of my panel work. It can be done, it, like other things in life takes practice to achieve good results.

340 is correct. TIG puts more heat into the metal then MIG. This should actually lead to more warping. The real advantage of TIG is the metal is not hardened as much after welding as it is with MIG. Tig welds can be easily hammer and dollied while MIG welds are often hard to work and can be brittle. On the other hand if you are careful with the MIG there will be little to no warpage when done correctly.
