    I'm new to welding (teaching myself TIG). I've welded a few frames and each time I weld them they end up warped in one way or another. I use a 45 degree vice and spot weld each corner, then one i have the frame spot welded I finish off the welds doing opposite corners from the outside in.

    Once cooled down I put the frame on a level surface and it rocks and\or its no longer square\rectangle.

    What am I missing? Is there any tips on how to keep it square? Is it possible to put heat in a certain part of the frame to even it out?

    Any advice, links, tips etc would be fantastic!!

    with the frame flat weld the verticals first in an upwards direction, always welding opposite corners
    flip it over with the 45 mitres, flip it again and weld the last mitres
    make sure your tacks are big enough
    weld one frame check it and adjust your weld sequence after that
    keep fillet size to a minimum
    always weld in the same direction on all corners, inside out or outside in
    If you are learning TIG, things will tend to distort more because you are a bit slower
    good luck
