Electron beam welded high thickness Ti6A14V plates using filler metal of similar and different composition to the base plate

Compositional changes of the welds carried out by the electron beam welding process have been investigated in the present work. Addition of a filler metal in the weld fusion zone has been used to solve some problems by improving the behaviour of the joint by minimising either the porosity, the notching or the cracking susceptibility of the joint (Sanderson et al., Met. Constr. Br. Weld. J. (1972); Atsuta et al. 3er CISFFEL, Lion, Francia, September 1983; Nazarenko and Kaidalov, Technological procedures of electron beam welding and repair; Murphy and Turner, Weld. J. (1976)). Filler metal can also be used to weld high thickness plates by low-power electron beam welders (Ruge and Oestmann et al., Decker. Electron and Laser Beam Welding, 11W, 1976). The main purpose of this work is to investigate the behaviour of a 17 mm Ti6A14V weld by the electron beam welding process with a filler metal of similar and dissimilar composition to the base plate. In the present work the initial results of 17mm thickness Ti6A14V plates welded with a 3 kWEB welder and a filler metal of titanium alloy of the same and different composition to the base metal are presented.
