Abstract

Welding trials have been carried out on 2 in thick Ti-6A1-4V bar using a 60kV 15kW Sciaky electron beam welding machine. Optimum single pass, butt welding conditions were determined using visual, radiographic, ultrasonic and metallographic inspection, across weld hardness surveys and tensile tests. Narrow, full penetration welds with almost parallel cross sections were produced. A stress relieving treatment for the joints was determined from the results of stress relaxation tests on weld metal and on parent metal.
