Abstract

Abstract

Based on the analysis of the density, specific heat and thermal conductivity of TC4 and TA17 titanium alloys by using JMATPRO thermodynamic software, the vacuum electron beam welding experiments of TC4 and TA17 titanium alloys with a thickness of 50 mm were carried out. The parameters of high and medium voltage accelerating voltage, different welding beam current and welding speed were designed. The effects of welding process parameters on weld width, penetration and weld forming coefficient were studied. The test results show that the penetration and weld forming coefficient of TC4 titanium alloy are higher than TA17 under the same welding process parameters. The influence of welding beam current on penetration and weld forming coefficient is the most prominent. The high voltage of accelerating voltage 150 kV is more suitable for vacuum electron beam welding of large and thick titanium alloys.
