(OP)
Is it possible to weld the above materials? QT400 apparently is listed as Weldable. I know portions of the weld will go through the HAZ...

This grade is weldable but an odd combination with structural tubing. What the heck are you doing with this combination?

It is formable and weldable. You are going to have to carefully watch your interpass temperature for welding to this material to avoid altering bulk mechanical properties. I would suggest keeping the interpass temperature below 350 deg F and watch the heat input.
