Re: Welded Frame Horror Stories

I was under the impression that, with the exception of the fact that you're adding extra metal around that joint, a weld is actually far weaker in a heat treated alloy. For example, with 6061 T6, the weld is reduced to T0, and therefore, the weld was at a disadvatage to the rest of the material. The only way to restore the strength is to reduce everything to T0, and re-heat treat.

On a side note, what's a good way to heat sink a frame so that it warps far less when welding? I remember 67 talking about doing that when they were welding their 2005 bot. I also thought they re-heat treated it.
