Abstract
A method for repair welding a titanium compressor blisk using laser twist welding. A blisk assembly has damaged portions removed. The surface to be repaired is provided with a predetermined geometry. The portions to be repaired are surrounded by a fixture which contains a laser nozzle. The fixture can provide a protective atmosphere to the area under repair while also shielding adjacent areas from damage resulting form welding. The welding is accomplished using preprogrammed patterns. The welding within the fixture is monitored remotely and is adjusted when stand-off between the weld nozzle and the molten metal are not within a predetermined range.
