Abstract
A method of and apparatus for repairing a defect in a surface are provided, the method comprising the steps of a) providing a bolus of an at least partially liquid alloy in a charge chamber, the charge chamber having a closable outlet and a closable pressure inlet; b) introducing a pressurized fluid to the charge chamber via the pressure inlet and accelerating the bolus such that the bolus is ejected from the charge chamber via the outlet; c) directing the bolus along a pathway between the charge chamber and the defect such that the bolus contacts the defect; and d) solidifying the at least partially liquid alloy while it is contact with the defect.
