should i be concerned?

It looks fine to me, and better than many of my welds with my $90 Harbor Freight flux wire welder (ugly, but work). I suspect that someone beefed up the anchor just to be safe. The factory often didn't weld it all the way around and I have heard of them breaking, particulalry in the rusty north. I sure wouldn't cut it off to fix. If still concerned, take it to a shop and have them clean up the weld and go all the way around.
