How hard is it to weld a frame?

[EddyCurrent]

I don't know how your frame is designed, but keeping in mind everything that others have said, my plan to get around 'weld twist' was like this;

1. weld the lower frame (blue) and fit heavy duty adjustable feet
2. bolt the beams (grey) to the base, add shims to get both sides parallel in all planes.
3. use the 'epoxy' method on top of the grey beams for final levelling.
