Yes, Tig weld would be best but the OP will need to grind out the existing weld and add some more metal to fill in the crack. If the OP didn't already have a replacement rack I would suggest welding it but for a couple of bucks and about 30 mins you could get almost similar results with JB weld.
Back in my low income college racing days I fixed all kinds of bike stuff with JB weld:
Brake bosses, pedal axles, I even used it on an old steel frame with a cracked rear brake bridge that had been driven into a garage on top of a roof rack. All of the repairs held for as long as I owned them.
