Maximum thickness versus depth of metal welded?

When you say thickness of metal up to 1/4" or 5/16" is that the depth of metal that the weld penetrates? So if I were welding two pieces of 1/4" angle iron (like making a corner) then the weld should hold fine. But what if I were welding 1/4" angle to a base of say 1/2" thick (both pieces being mild steel) would this weld hold since one piece is 1/4" and the larger piece is 1/2"? Great course so far by the way!

You could weld 1/4" to 1/2" because you always set your welder's voltage for your thinnest material. But 1/2" to 1/2" and its on to stick welding.
