Welding for the aerospace industry requires an extremely high level of precision. For products to work in a zero atmosphere, air tight joints are essential, making laser welding the perfect choice. Carrs are currently involved in welding part of the reaction wheels used by New Space Systems. These wheels are increasingly popular for use in satellites and spacecraft for full three-axis manoeuvrability and accurate speed control. With huge success, these wheels have been exported to the USA, Indonesia, China, Spain, Germany and Italy.
