Tubular upper a-arms - Should I be worried?

These are from a reputable (as far as I have gathered) vendor of suspension parts. The tig welding at the ends of the tubing, which looks nice, should cause minimal distortion from cooling, right? These weren't that cheap ($200 so far), but I felt I could install bushings and ball joints and POR15 them myself to save a little change compared to other vendors' products. This is ongoing - will keep y'all posted. Thanks
