Hi Xander, personally, I should have fed more solder and flux to the inside of the tube to form a fillet there, as you are deliberately removing the external fillet of solder with the external material, and if you radius or chamfer the corners will have very little of the square tube metal for the solder to have any strength. Pre-formed shapes of flux-cored solder fitted inside the tube when assembling the final end can achieve a fillet, but capillary action through from the outside won't do that. IMHO?
I should have silver-soldered the assembly simply because I can, and it is a stronger joint material.
