Aerospace Laser Welding

Aerospace - Sky high laser welding Carrs Welding have been welding pumps and sensors for various aerospace projects for over 5 years and supply many blue chip companies in the sector. We are normally involved right at the start of a project, as we did with the new Airbus A380 where we were asked to weld a permanent magnet motor which has a crucial role in the operating of the aircraft. Test-pieces are welded at the time of the development and a laboratory test report retained certifying the acceptability of the welding to the standard defined at the outset of the project. Free issue parts are supplied to us and we retain the tooling developed at the time of the testing programme. Carrs train coded welders specifically for such critical jobs which are carried out on our Robot laser welding systems. The manipulation of the job and laser and the power and speed settings are all stored electronically for maximum repeatability and quality. Anti-vibration device Case 1 - Anti-vibration device. Turbo prop passenger planes encounter problems with vibration and we developed a device which creates an anti-wave within the cargo bay thus reducing the noise. The aluminium casting involved was welded together and then helium leak tested for quality assurance. Laser welding was crucial for this application so that the aluminium connector weld did not overheat the electronics or distort the casting. Carrs continue to weld safety critical jobs on aircraft; devices like this are often inaccessible after installation and have to function without failure for the lifetime of the plane; you can count on Carrs for this level of reliability. Cable harness Case 2 - Cable harness. Cabling that is routed right into the engine can be exposed to high temperatures. Carrs successfully welded a small steel ferrule on wiring looms for a Pratt and Whitney engine. The 0.2mm stainless steel ferrule needed welding without damaging the cable insulation through excessive heat; laser welding is perfect for this job. Carrs satisfactorily performed the initial trials and the first production batch, and on-going production has been carried out in the USA.
