Ya, with that kind of stuff, one can make a nice looking weld with the wrong filler metal that would be a hit on instagram but it could look like an aero bar on the inside. I'm sure in the case of the LTR welds they aren't full of holes or anything like that since there's a few different and fast ways to do NDT on weldments, I'd guess it's more to do with the weld design than anything the actual welders did.
