  • Method of repairing a metallic artifact
    Patent number: 8322008
    Abstract: A method of repairing a metallic artefact (40) with an open defect in or on a metallic surface or substrate of the metallic artefact includes cold forging the open defect to close the open defect and thereafter laser cladding the cold forged defect with a plurality of laser clad beads (44) applied to the metallic surface or substrate to cover the cold forged defect with a cladded metal layer.
