A method of repairing a metallic artefact () 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 () applied to the metallic surface or substrate to cover the cold forged defect with a cladded metal layer. Advantageously, in-situ repair of fluid-filled vessels, pipes or the like is made possible by the repair method, in some instances eliminates the need to shut equipment down thereby reducing downtime and the cost associated with lost production.
