Frame Welding

I am going to go pick my frame up from the shop where it's been sandblasted
and shot with a coat of primer. I am aware that TRF sells a re-enforcement
kit for the know weak spots on the frame like the differential mounts but
here's the part I don't know:

What welding method should be used to attach the parts (MIG, TIG, whatever)?
