You are welding a three inch long "tee" joint. You start on the left side at point "A" , and finish the left side at point "B".
You then immediately move to the right side, and weld from point "A" to point "B".
In what direction will the upright tend to distort? Will the distortion be uniform from A to B, or will that also distort (creating a twist)?
Thanks,
Jon
