摘要

Method for repairing shut-off devices and control devices in power stations comprises leveling a planar and/or curved damaged surface inside the device by grinding, rotating and/or cutting to regain the planarity, curve and/or height of the surface, adjusting the alignment of a drive and/or guide of a welding and/or shearing tool with respect to the device and fixing the drive and/or guide with respect to the device. Preferred Features: The method additionally comprises machining the surface by grinding, rotating and/or cutting and resurfacing using built-up welding, especially tungsten inert gas welding, metal arc shielding welding and/or flame spraying.
