The paper presents microstructure investigations as well as properties and technical parameters of welds made using the electron beam welding method (EBW). Electron beam welding is a bonding process, especially suitable in the case of titanium and other oxidation-sensitive materials, because it must be carried out in a vacuum. Integrity of the joint was determined on the basis of mechanical properties and microstructure evaluation. The micro-hardness of the weld was measured with the Matsuzawa-Vickers MX 100 – a load of 100 G (0.98 N) was used. Nikon Eclipse MA200 microscope was used to examine the microstructure and determining the size of individual articulation zones.
