Abstract | The optimum processing conditions for joining thin sheet materials (1–3.2 mm) of commercial purity titanium and Ti-6%Al-4%V by electron beam welding were determined by using single- and double-pass melting sequences. For commercial purity titanium weldments, the tensile properties were observed to be similar to the parent material and independent of the sheet thickness and the welding procedure. However, for Ti-6%Al-4%V, the processing conditions during welding were observed to change the characteristics of the alpha lamellae spacing and plate thickness, which in turn influenced the properties. Hence, for joining alpha-beta titanium alloys with use of electron beam welding, the definition of critical processing conditions enables optimization of the structure-property characteristics of the joint. |
