Research at the University of Manchester on laser cleaning of Ti alloys has resulted in practical implementation of the technology at Rolls-Royce for the automatic preparation of surfaces prior to electron beam welding. This has been applied to 24 different aero-engine component types including compressor drums across most current engine families. This has resulted in close to 100% ‘first time right’ aero-engine component welds. The technology is also being adopted by BAE Systems to replace chemical cleaning during airframe manufacture. The elimination of manual and chemical cleaning processes results in savings of several million pounds per annum.
