You are correct...probably cost $10-$15k to get a qualified weld repair method down here in Oz...then implementing it.
Just gluing bits together with GTAW is not a "repair"...might work on teapots however...
Tig welding is not gluing.
You could weld that no problem.
If the driveline tunnel is cast and solution heat treated aluminum, then welding it will put it in an annealed condition. The heat affected zone looses 2/3 of it's tensile strength in that instance. Now, it seems like a small area, but that driveline tunnel is probably seeing a large percentage of it's stress reverse when going over normal road variations. Cycle fatigue could result in the area cracking again, and in an undetected manner.
I'm not saying I wouldn't fix it and drive it myself. Im just pointing out that when using a material like heat treated, cast aluminum, field repairs to original specs become difficult to impossible.
