TIG Question: Keeping everything squared up
I just got my TIG and am building a welding table and am having problems keeping everything squared up. I use a Jet bandsaw to make all of my cuts and have the blade squared up the best that I can. I clamp the square tubing to the table top and tack weld each side before making a full pass weld. I also let the piece cool before unclamping.
But, when I unclamp the piece, it will always be off and not perfectly square. Is there anything that I'm doing wrong or overlooking? Any advice would be appreciated.

Re: TIG Question: Keeping everything squared up
Can you provide some pictures of the assembly and your fit-ups? The direction of heat and order of your weldments will affect the material drawing in a certain direction. Below are a few pictures of the band saw stand I made from 304L 2"x2"x7 ga. and 2"x3"x7 ga.
I built it on a pipe vise equipped bench with the aid of a couple Ridgid pipe stands. For square/rectangle tubing, it is best practice in the case of mitered 45s to weld the heel of the 90* first, weld the sides toward the heel, and last weld the throat. The draw created by the fillet weld is pretty strong - especially if you 45* cuts are not accurate and you have a resulting air gap in the throat.
What directions are your assemblies drawing towards after welding/cooling off?
