Abstract: PROBLEM TO BE SOLVED: To effectively weld-repair an airfoil 52 made of a nickel-based superalloy which is hardly weld-repaired. SOLUTION: A method for weld-repairing an airfoil 52 made of a nickel-based superalloy includes a step of machining the surface of the airfoil 52 into a relatively smooth surface, and removing a damaged portion of the airfoil 52. Next, a powder alloy such as IN-100 is fed to plasma arc welding equipment. A plurality of weld beads 60, 62, 64, 66 are deposited along the damaged portion of the airfoil 52 by the continuous bi-directional movements 70, 72 of the welding equipment so as to eliminate abrupt thermal transients at an end of the weld, and the thermal stresses to cause cracking in susceptible alloy such as IN-100 is reduced thereby.

Abstract: A method for weld repairing airfoils made from nickel based super alloy material is provided. The method includes removing a damaged portion of the airfoil by machining the airfoil to a relatively smooth surface. Powdered alloy material, such as IN-100 material is then fed to a plasma arc welding device. A plurality of weld beads are deposited along the damaged portion of the airfoil in a continuous bi-directional pattern by the welding device to eliminate abrupt thermal transients at the ends of the weld, thereby reducing the thermal stresses that cause cracking in susceptible alloys such as IN- 100.

Abstract: A method for weld repairing airfoils (52) made from nickel based super alloy material is provided. The method includes removing a damaged portion (56) of the airfoil by machining the airfoil to a relatively smooth surface. Powdered alloy material, such as IN-100 material is then fed to a plasma arc welding device (10). A plurality of weld beads (60) are deposited along the damaged portion of the airfoil in a continuous bi-directional (70,72) pattern by the welding device (10) to eliminate abrupt thermal transients at the ends of the weld, thereby reducing the thermal stresses that cause cracking in susceptible alloys such as IN-100.
