Neat video, but what is this factory team member Tig welding? Looks like a structural reinforcement behind the area he is working on, but the flange doesn't looks familiar. It appears he is working in a 911 area, whether it is regular production or specialty (i.e. racing) as opposed to an area for the 917 that was shown, but I'm not sure how cramped the factory really is! I've looked at heat exchangers, front struts, rear trailing arms, and torsion tubes. Any ideas?
