Hopefully Rick will be able to give me some guidance.
On another forum a joint is pictured for a 90 degree corner where two pieces of angle iron come together. The joint in question is the 3rd picture from the top in this link..
A few responses down in this link a fellow defines the joint as a "block and chip" joint and suggests if it is done correctly it has minimal distortion but does not provide any suggestions as to the specifics of "paying attention".
Given that I have a need for several minimal distortion corner joints to build a rectangular frame I thought I would ask our new resident expert if
(a) he knew of a similar joint that could be used for heavy rectangular tubing ... 2 x 6 x 3/8 ... and
(b) what the recommended weld order and direction might be to minimize the distortion.
My original intent was to simply miter the joints at 45 degrees and weld it together but after some research I think the mitered corner joint is probably the most susceptible to distortion and my rectangle will turn out to be a pretzel.
Any suggestions would be appreciated.
Thanks,
Arvid
