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 m etal in the weld fusion zone has been used to solve some problems by improv ing the behaviour of the joint by minimising either the porosity, the notch ing or the cracking susceptibility of the joint (Sanderson et al., Met. Con str. Br. Weld. J. (1972); Atsuta et al. 3er CISFFEL, Lion, Francia, Septemb er 1983; Nazarenko and Kaidalov, Technological procedures of electron beam welding and repair; Murphy and Turner, Weld. J. (1976)). Filler metal can a lso be used to weld high thickness plates by low-power electron beam welder s (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 1 7 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 wor k 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 comp osition to the base metal are presented.
