Tube welding question

[agent4573]

So I have two tubes that intersect at a 90 degree angle. They don't intersect through each other though, as one sits on top of the other. I was just going to make some quarter-round gussets to connect the two together, but are there any better options or standard practices to use? It is a load bearing part, but not a critical junction.


*EDIT* In the picture I added, you can see the two long tubes sticking out the back go under the rear crossbar tube. Just looking for the best way to weld up that intersection.
