If you do weld, make sure that the materials are compatible!
Also, the key way option lets the gears stay intact in a high stress situation. In situations like that, the gears teeth will break faster than the weld will, so if you have a couple spare boxes laying around, I would weld them, but keying is much more reliable and easier to change in a breaking situation.

That is one reason we don't weld gears onto shafts anymore.
