When section thickness, increases more than 5mm, high energy density process like Electron Beam Welding (EBW) is advantageous than conventional Gas Tungsten Arc Welding (GTAW). The inherent vacuum conditions of EBW process make welding of Ti6Al4V more appropriate. However, it is generally observed that certain alpha/beta alloy of titanium welds made by EBW tend to exhibit lower values of toughness compared to their base metal counterparts (1) which is attributed to the alpha prime martensitic structure formed due to higher weld cooling rates.

Abstract


When section thickness, increases more than 5mm, high energy density process like Electron Beam Welding (EBW) is advantageous than conventional Gas Tungsten Arc Welding (GTAW). The inherent vacuum conditions of EBW process make welding of Ti6Al4V more appropriate. However, it is generally observed that certain alpha/beta alloy of titanium welds made by EBW tend to exhibit lower values of toughness compared to their base metal counterparts (1) which is attributed to the alpha prime martensitic structure formed due to higher weld cooling rates.
