    I am making a stand for my little CNC Boxford lathe and mill. It's 40mm box and so far I have made the bottom and top frames, these are welded and they are pretty flat.

    I have now tacked 4 uprights on each corner and the next part is to weld these up.

    Can anyone suggest a sequence to minimise distortion

    I would start placing stitch welds nearest to the apex of each corner; apparently corners suffer the least distortion. I would stitch one, then the opposite side of the same leg, then I would move to the leg diagonally opposite and repeat the above, once all four legs have a stitch weld across I will fill each face of the corner along the lines of 1, 3, 2, 4 ensuring that leg is fully welded then move on to the next leg to complete.

    It's done, and still flat, no pictures as I was pushed for time last night.

    I did opposite corners on one level first but didn't fully weld in 1 go, not sure how to explain but will try

    I did 1 side of a leg then moved to the diagonally opposite leg and did 1 side of that, repeat on each leg until all were done then flip the frame and repeat for the other level

    And some of the welds are visually good, others need a meeting with Mr Grinder :laughing:

    @Yamhon I think I followed what you said, well at least my interpretation of it

    Cheers :thumbup:

    The easiest way to remember......whatever you do to one side, do the same to the opposite side. That includes allowing it to go cold, or to the preheat applied.
