does anybody know how to weld (weld rod used) on an x350 -specificly the bracket that holds the front bumper reinforcer (re-bar) to the frame -thanks in advance

 

See the other post on this. Jaguar already have used two TIG welds (I think it was TIG, but it might have been plasma), on the shell to fix the back of the roof pressing to the D posts. There may also be two at the front.
