Abstract
In the particular embodiments described in the specification, a vacuum furnace includes a conveying arrangement for holding four solid metal members with their end faces in closely-spaced relation and an energy beam gun directs energy to the adjacent faces to melt the metal. Metal ejected from the heated surfaces by explosive vaporization of inclusions in the metal is trapped by the adjacent surfaces of the other metal members.
