Shape character of fusion-solidification zone of electron beam welding (EBW) joints was studied for TC4 alloy.Four typical shapes of the fusion-solidification zone were gained by appropriate welding processes.The shapes and dimensions of the fusion-solidification zone of TC4 titanium joints were apparently influenced by processing parameters,focusing state and power density distribution.Based on the analyses of processing parameters,focusing state and power density distribution,the integrated parameters of n1 and n2 were put forward,which represented the distribution and intensity of electron beam energy.And a series of the formulations are developed to predict the shape of fusion-solidification zone by the processing parameters.
