Abstract
PURPOSE: To provide a simple method of repairing castings without selfpig-making action and much residual stresses by utilizing super-plastic solidus sealing method and specifying shape of a filler metal.
CONSTITUTION: A defective portion 1a of a casting is filled with a conical or semispherical filler metal 2 in which the height h and radius r of a projecting portion thereof are in relation with each other such as h/r=0.02W0.3. While a proper pressure is applied to this filler metal and defective portion of casting, heat cycle is given to raise and lower transformation temperature range of casting material and weld said portion completely to the filler metal for repair.
