Our client, a major jet engine manufacturer, required a high precision fixture for holding aerofoil blades whilst welding.
The fixture has a fabricated base that bolts onto a universal manipulator, allowing for maximum access for the operator. In the centre of the fabrication there is a large ground location ring for the blisk to mount. Out riggers then come out from the fixture to support a large aluminium casting, measuring just under 3.6metres in diameter. This casting is precision bored on our five axis to accept location pins. These location pins accurately position the Aerofoils in position whilst welding.
The entire fixture is inspected using our Laser trackers to ensure the high tolerances are achieved. This report then becomes the basis for recertification in the future.
