TIG can be less effective considering the access to the part. In confined, tight areas, it can be impossible to get the TIG torch where it needs to be - not to mention the filler rod.
I would recommend MIG for this type of modification. I would also say the quality of the work will be more dependent on the cleanliness and fit of the work way more than the type of process used.
Tom is correct. If you have a welder who is good with TIG, and can access the weld, that will work fine. But if the welder is more comfortable, and better qualified, with MIG, then use MIG. Either process will work with mild steel, alloy steel, or stainless. It's just a matter of using the right materials, and the right procedure. But either MIG or TIG can be qualified to produce "X-ray" quality welds.If the technician is good at what he does, then both types of welding are great
