The arc and laser weldabilities of two Ir-0.3% W alloys containing 60 and 200 wt-ppm Th have been investigated. The Ir-0.3% W alloys doped with about 60 wt-ppm Th are used as post-impact containment material for radioactive fuel in thermoelectric generators that provide electrical power for outer planetary missions. 18 refs.
