Default Grinding your welds

Great welders make great welds that need no additional clean up to look good. The rest of us may sometimes need a grinder clean the welds up a bit and or smooth them out.

Does grinding the surface of the weld scratch or score the metal in such a way that it makes it easier to start a fracture at the scratch line and break? Does the direction of the scratching matter?

Does putting a radius on the weld (through grinding) weaken the weld? I am not talking about digging back into the parent metal just knocking the top off the weldment which leaves a radius.
