Abstract: A method for repairing a defect affecting a weld. A sheet of filler metal is placed on the surface of the welded part, next to the region of the defect. The sheet is locally welded to the welded part in the region of the defect using a friction stir welding tool having a retractable welding pin. The welded part and the sheet are separated such that the filler metal amalgamated with the metal of the welded part remains in position. The local welding operation includes successively performing the following: setting the welding tool into rotation and putting it under pressure; inserting the pin to a small distance from the anvil while maintaining or increasing the pressure on the shoulder of the welding tool; progressively retracting the pin while maintaining or increasing the pressure on the shoulder; and stopping the pressure on the shoulder when the retractable pin has been retracted.
