Quote: Cleaning up the welds by grinding on them,in my opinion is weakling then. Un-less you re-weld them. There is lots of skill needed to build a car correctly, and safely. By no means Am I sticking up for the manufacture of your parts. I am just stating some facts that are overlooked.
the welds don't look too bad for tig welds, and grinding them smooth eliminates stress risers. rule of thumb in my field (I'm an engineer who does structural analysis on welded steel fabrications in large equipment) is that grinding a weld smooth will yield a ~2x improvement in fatigue life in steel, I don't have experience with aluminum.
a number of "problems" in the pics I see (the unusual bend in the K-member, etc) could very well be shipping damage. the cutouts/clearancing for the rack looks kinda hokey.
