Build-up strategy for a crown base of a turbine blade, and turbine blade

A device for clamping a turbine blade () during a welding repair of the blade tip (). The blade has a peripheral surface that has a suction side () and pressure side () and has a blade tip. The device has at least one movable clamping structure () for pressing on the suction side () or the pressure side () of a turbine blade () in the region of the blade tip () of the turbine blade, wherein the clamping structure () is designed to remove heat from the turbine blade (). The at least one movable clamping structure () has a plurality of clamping elements (), which are each individually movably supported in such a way that the clamping elements can be moved toward the peripheral surface of a turbine blade () to be clamped and away from the peripheral surface.
