Some of the sub assemblies were done in machines and the welds might have been more or less well spaced. The manual operators could be all over the place. Even spacing was only as good as the guy's judgement and his control of the weld gun. Some guns were pretty big and cumbersome and took a while for the operator to get used to them. I feel sorry for anyone dealing with the general public.
