Ok, heres some pix. The red lines represent what you got going on which is about 20° per side equalling about a total of a 40° V notch. The blue marks are 45° per side equaling a total of 90°
you need more width, and depth, and the tubes need to be ground down to damn near a point all the way around to get full penetration. If you dont do that and get a good solid weld, I would not recommend grinding any of the excess off to make a smooth tube since It will eventually break.
