On Fallout 3, the stealth suit and any melee weapon will help you kill a Deathclaw.
On RFallout New Vegas it's different because of the damage/dps thing they put in, Deathclaws have a massive resistance to damage so you need some high powered explosives or a sniper rifle/energy weapon equivalent to do any real damage to them.
