Thank you. I understand that. What do you think he was referring to then about the "freezing". Maybe he meant they cooled it at a rapid rate?whole thing is cooled at 1 time so the metal solidifies and makes 1 crystal.. so it is all one melecular piece..
when you weld something together is the metal or the weld stronger? The weld is, and the metal on the side of the weld is the weakest spot. In this same theory, when something is cast.. it is all the same temp and it cools at the same time so there is no issue with bonding between parts.. it is all 1 piece structurally.
