TWI Industrial Member Report Summary 774/2003
Andrea Gregori takes a long hard look at the existing literature related to welding and repairing nickel superalloys and summarises his findings with respect to cladding and build-up of nickel superalloys.
The high cost of damaged blades and nozzle guide vanes in the high pressure section of aeroengine, industrial derivative and power utility gas turbines has led increasingly to end-user interest in the use of repaired components. TWI has undertaken a review of current industrial practice regarding repair of nickel superalloys, to provide a basis for experimental investigation of specific industrial problems.
