<p>A method of repairing a turbine blade (10) of the type having one or more lacing wire holes (20,21) comprising the steps of welding additional metal (17) to the blade (10), subjecting the blade (10) to a stress relieving heat treatment process before which the or each lacing wire hole (20,21) is effectively eliminated by filling the hole or holes (20, 21) with material the same as or at least compatible with the material from which the blade is made. The turbine blade (10) may be subjected to the application of mechanical forces to restore its form and machining to restore its shape can be gauged to ensure both its form and shape is correct.</p> |
