Weld C6x8.2 perpendicular to TS6x3x3/8

Weld C6x8.2 perpendicular to TS6x3x3/8

(OP)
I would like your opinion regarding the potential impact of welding a C6 perpendicular to a tube steel member (C6x8.2 - TS6x3x3/8), the 6" dimensions match up.  Assuming an equivalent weld size of 3/16" on both flanges and the web a direct weldment qualifies.  One specific is that the weld on the top flange must be flush with the two members; this eliminates a plate that extends above the TS/C6.  A flare bevel weld on both flanges results in an effective throat of more than 3/16" (5/8 x (t=.375) = .23" (per AWS D1.1, figure 3.3).
Even with an interstial plate between the channel and the tube wall the effective throat would be the same and adequate.  I performed a rough check on the punching shear of the tube's wall using criteria in the AWS D1.1 and it checks out OK.

Does anyone have any anecdotal comments regarding similar joint configurations? One concern that I have is that the radius on the tube corner can range from less than the thickness of the wall to as much as three times the thickness, therby increasing the gap between flange and tube.

I would appreciate hearing from you,  thanks in advance :>)
