preferable alignment of plate edge to SHS tubing corner

admin

Hi all,Please see attached image. Materials are steel with yield strength of 350MPa. Plate 1 and 2 are to be welded to 35mm SHS tubing. The SHS tubing for Plate 1 is 3mm thick with 6 mm outside radius. Tubing for Plate 2 is 4 mm thick with 4 mm outside radius. Weld fillet is to be 4mm. I wanted to know which configuration of alignment of the plate edge face to the SHS corner is best for welding ease and weld strength. Thanks in advance for your answers. Attached Images
Reply:flat surface 90*ed to Flat surface "L" will be the easiest to weld though, bringing the plate over the radius some will create a bit of a automatic bevel.There are no problems. There are only solutions. It's your duty to determine the right one.Hobart Handler 210Airco 225 Amp MSM Stinger
Reply:Is there a reason you're having the plate cross all the way across the tubes? I'd consider trimming the plates back to the tangent point of the square tubes, to save some weight and material. In shear it won't make any difference in strength. In axial the smaller plates should be a bit stronger.Last edited by fortyonethirty; 10-11-2012 at 07:23 PM.Ian TannerKawasaki KX450 and many other fine tools
Reply:Thanks for the answer. There's no reason to hang it over. I just thought that it would be a stronger weld since there is more surface area.
