Originální abstrakt

Electron beam welding offers many advantages over other methods of fusion welding. High current density of electron beam is one of the advantages. Energy delivered on the surface of welded components allows rapid melting and evaporation of base materials. It is possible to weld materials with the different thermophysical properties under condition of appropriately adjustment of process parameters. One of the examples is welding of aluminum and titanium alloys, which provides suitable combination of physical and mechanical properties, especially for aerospace and automotive industry. Fusion welding of these materials is associated with the formation of intermetallic phases during mixing of basic materials and subsequent solidification and cooling of weldment. In this work was evaluated influence of welding speed, oscillating frequency, beam focus and offset of electron beam on the structure and integrity of welded joints. The resulting weld joints were evaluated by using light and electron microscopy. Type of intermetallic phases observed in the welds was determined by EDS analysis. Estimation of mechanical properties was carried out on the base of measurement of microhardness profile across weld joints.
