  • WELDING METHOD USING COATED ABRASIVE PARTICLES, COATED ABRASIVE PARTICLES, COATING SYSTEM AND SEALING SYSTEM
    Publication number: 20220213366
    Abstract: A welding method using coated abrasive particles, coated abrasive particles, coating system and sealing system which uses particles, in which a hard material layer is applied around abrasive particles such as cubic boron nitride (cBN) and protects against oxidation during welding. The hard material compound in the coating may include a carbide, in particular titanium carbide. A sealing system is composed of stator and rotor blade having the layer system.

  • Device for clamping a turbine blade
    Patent number: 9878411
    Abstract: A device for clamping a turbine blade (9) during a welding repair of the blade tip (11). The blade has a peripheral surface that has a suction side (5) and pressure side (7) and has a blade tip. The device has at least one movable clamping structure (1,3) for pressing on the suction side (5) or the pressure side (7) of a turbine blade (9) in the region of the blade tip (11) of the turbine blade, wherein the clamping structure (1,3) is designed to remove heat from the turbine blade (9). The at least one movable clamping structure (1,3) has a plurality of clamping elements (13), 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 (9) to be clamped and away from the peripheral surface.
