That flange is part of the long side axle,
bend it straight, weld that cup back together,
get some 5/8" (sorry I don't know the mm size)
balls in that CV and go wheeling, put a CV boot
on it if you have one, if not stay out of the bad stuff,
but then again, who cares, you are going to replace it
soon after the trip, so go have fun.
