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?
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
