On another thread there was a difference of opinion on the desirability of grinding the weld beads on titanium frames completely smooth. It was offered that the best "raw" beads (small, delicate, neat, etc.) showed the skill of the welder who would never want to grind them smooth and hide his skill. It was also suggested that some folks may prefer a perfectly smooth, unified look obtained by starting with slightly larger beads that are subsequently ground perfectly smooth and curved into the miter. What do you think and prefer given no difference in strength and durability: very well done natural, raw welds or perfectly smooth beads finished by grinding after welding? I suppose this question could also pertain to aluminum so feel free to opine on that subject as well.
