Abstract
A device for recontouring a gas turbine blade includes at least one support configured to rest on an edge of the gas turbine blade during the recontouring, at least one side bearing configured to rest on an intake side or an outlet side of the gas turbine blade during the recontouring and a machining unit for machining the gas turbine blade. The machining unit is configured to fuse at least one partial area of the edge of the gas turbine blade using a beam of energy that is targeted such that material of the blade solidifies into a new contour, substantially without the addition of supplementary material.
