For a lightsaber to melt steel it has to be pressed on it and held there, remember ep 1?
Becides, if wolverene can survive a suped up nova melting most of the flesh from his bones, growing back in less then a minute (well long enough so he looks like a zombie and can still fight
) then he should have no problem with maul.
BUT! The image shows boneclaw wolverene, who wouldnt beable to grow back unless he put his limbs in place.
So Maul Wins that one.
