FYI, rack mounts are usually brazed on, not welded.

I can tell you from experience that TIG welding them is difficult! The problem is that the rack mounts are thick steel while the frame is very, very thin steel. If you try to weld the rack mounts without preheating them, you'll burn a huge hole in the frame (DAMHIKT) before the mounts are even warm. If you pre-heat them, they become difficult/impossible to handle and position. Brazing usually works well enough, if it's done by someone who knows what they're doing. That probably means a frame builder, not a welder... I used silver brazing to attach rack mounts to the commuter bike I built.
