Tubular upper a-arms - Should I be worried?

TIG welds Should never need to be cleaned up. They should be the same color or as some sort of blue/purple. Dark, sooty grey colored(or dull, non shiny) welds is a clear indication of too much heat input, or poor gas coverage. Heat is the enemy of metal properties...that's why most weldments will crack along the edge of the weld...most heat input with no filler material added. It's just mind boggling what people will buy.
