A method of restoring a gas turbine engine component includes repairing a turbine airfoil along a chordwidth dimension to rebuild a trailing edge of the turbine airfoil to near original dimensions. An eroded portion of the trailing edge of the turbine airfoil is removed and a filler material is deposited onto the trailing edge to produce a laser cladding. During the laser cladding process, a barrier member is inserted into a slot that extends through the trailing edge to prevent filler material from entering the slot and to act as a heat sink to remove heat from the trailing edge during the laser cladding process.

A method of restoring a gas turbine engine component includes depositing a filler material onto a sulphidation section of an underside of a turbine engine platform and laser consolidating the filler material to produce a restored surface on the underside. The sulphidation section includes sulphidation pit portions that are filled during the laser consolidating to produce the restored surface. An eroded trailing edge of a turbine airfoil is laser cladded to produce a restored trailing edge thickness.

A metal article and a method for welding the metal parts to form the metal article, where the method comprises feeding filler material to an intersection of the metal parts, and melting the filler material with a laser beam to form a weld between the metal parts at the intersection.
