[QUOTE="bigj1972, post: 329631, member: 811"] Any time you change metal from a solid to molten, there is a slight expansion, then a greater contraction as it cools. The method of that melting process doesn't matter. Heat warp always happens, but can be controlled. Some try to use clamping type devices, but they are not very effective. An experienced welder knows how to control that heat warp by adjusting machine settings and using predicticable welds, not just going in like a machine gun, which sounds like what happened in your case. However, the will to achieve excellence, or the profitability of time spent can be factors that are just as relevant in today labs. [/QUOTE]
