That is not what I said. I did not say that chrome moly could not be welded. I said that "Heat treated" chrome moly cannot be welded without affecting the heat treatment. Welding produces heat! In essence, by repairing the crack you cause it to weaken, which eventually leads to it failing yet again and possibly in a more catastrophic way. Chrome moly alone did not give the engineers the strength they needed so they resorted to using a heat treated steel. There is no way to "cold" weld any steel! Therefore, this requires a leap of faith, you are essentially assuming that the part will never need welding! All Disney figures routinely fatigue crack and require periodic welding. Therefore using heat treated steel was an idea born in the mind of a structural engineer who obviously had no field experience with animation. Also in reference, to a prior comment about Yeti's movements being art directed to be more dynamic with the implication that this caused the multiple failures, this is a popular but incorrect Disney myth. I asked someone, who shall remain unnamed and not further described, who was directly, dare i say very directly, involved in the install process, and I was told that Yeti's motions where tuned DOWN not up as the popular but incorrect myth states. And regarding your question as to what knowledge I have lets just say that I have direct access to virtually everyone that was involved in the Yeti debacle as well as those who have been dealing with it throughout the years.
