Original abstract
Titanium alloys and their weld joints find wide application, in particular in aircraft, automotive and chemical industries, because of their outstanding specific strength and corrosion resistance. The high reactivity of these alloys and the strong degradation effect of elements contained in the atmosphere (H, N and O) make it necessary for these alloys to be welded in protective atmospheres or in vacuum. From this viewpoint, Electron Beam Welding (EBW) is an advantageous welding technology, in large series production. In the paper, the effect is studied of the spot diameter and beam focusing on the penetration depth and the weld shape in the Ti6Al4V alloy. The results obtained are complemented with an analysis of the microstructure and mechanical properties (microhardness, tensile tests) measurements across the welds.
