W126 cracked trailing arm. Can it be safely welded?

The right rear trailing arm on my 89 300SE is rusted out on the bottom and cracked up along the rear edge. I can't believe I never saw it before, I must be going blind. The car has always had too much camber in the rear wheels, more on the right than the left. I've been under it a half dozen times looking at the shocks, springs and bushings but I guess I wasn't in the right position to see the crack. The rust out wasn't too visible until the arm was wiped off.

It was my indie that found it. I gave up trying the figure it out and took it to him. He thinks a good welder can repair it so that it will be safe, and that new springs and shocks will correct the rear camber.

Does this sound right to our experts? I'd love to get some opinions. Thanks.
