The Nuclear AMRC was set up to help industry partners to win work in the civil nuclear sector – in new build, operations and decommissioning with the aim to reduce cost, lead time, cycle time, and risk in manufacturing and to improve quality. Large manufacturing facilities have been set up for working on production-scale technology demonstrators using an array of state-of-the-art manufacturing equipment. While Electron Beam Welding (EBW) is a widely used manufacturing technology in many sectors, so far this technology has not penetrated the nuclear industry. Acknowledging the great potential of EBW the Nuclear AMRC aims to change that by utilising its two EBW facilities. Many nuclear components are of large scale. Therefore an EBW facility with a vacuum chamber volume of 208 m 3 has been installed. This is currently the largest EBW facility in the UK. The mobile 30kW, 60kV gun is attached to an x-y-z gantry along with two rotary axes. These axes together with turn and tilt tables are all CNC controlled allowing a very flexible approach for welding of parts up to 100 tons with sizes up to 6 x 4 x 3 metres. This paper aims to introduce the EBW capabilities at the Nuclear AMRC and to present some of the achievements to date.
