TIG does work nice, but a MIG will do just fine for filling a seam. Once it's welded (properly)there is no chance of the seam opening up and showing a line in the paint---yes, they will do that when filled, even with lead!!!! Some good prep time cleaning the seam out, and patience in welding IMO will yield the best results....
