ABSTRACT:
An energy-beam welding method for two metal pieces is performed by bringing a cylindrical jig into axial engagement with one of the metal pieces at welding zone between them which are placed as joined, and irradiating an energy beam to the welding zone through the cylindrical jig in its axial direction, causing at least part of the energy beam reflected on inner peripheral wall of the cylindrical jig to be directed to the welding zone, whereby the metal pieces are mutually welded easily reliably.
