Cel The objectives of this project are: -realisation of defined penetration geometries or weld forms by examination of the correlation between beam and weld geometry -in accordance with this the selective, application specific development or improvement of beam generating systems -development and application of the signal analysing methods that allows process observation and quality monitoring and hence detection of certain faults or their causes -development of a computer-supported concept for efficient identification and optimization of appropriate process parameters -improvement of existing or development of new model concepts for energy conversion, dynamics of capillary action and heat flow with the aid of the results of the investigations. Within this project the spatial power density distribution of the electron beam was evaluated with a further developed beam measurement system on 12 different EB-machines. A complete description of the beam geometry along the beam axis could be done. The correlation of the power density distribution with the melting traces of Arata Beam test showed small deviations concerning the focus point. The influence of the welding position, accelerating voltage, beam power, welding speed, vacuum quality, aperture angles of the beam and beam diameter to the weld result could be extracted precisely. With this information a parameter transfer from on EB-machine to another could be done successfully with a time saving of apr. 40-60% compared with the conventional method. Furthermore, the observation during welding, by means of video and x-ray and electrical signal devices confirmed impressively the high dynamic of the process. Several kind of weld defects could be detected and interpreted. The results were main input for the development of models calculating the capillary shape and the spatial temperature distribution in and around the world. The results showed a good correlation with the welds and thermo-couple measurements.
