From high-end products for aerospace and engines to power plant construction and medical engineering - electron beam technology is an innovative method that straddles the border between basic research and application. Austria's only electron beam welding facility for basic research at the Institute of Materials Science and Welding at TU Graz, commissioned in 2012, is a Jack of all trades: apart from welding up to 150 mm thick steel and micro components, it can also produce alloys and treat surfaces. This process makes welding many times faster than the conventional arc welding. Welding tasks that used to take several hours or even days are now accomplished in a matter of minutes. In addition, the low heat input means that distortion and heat affected zone is minimal. As a result little or no reworking is required for the welded components, which reduces costs. Comparison between conventional arc welding (left) and electronic beam weld.
