Abstract:

High-voltage electron beam welding techniques capable of producing butt welds of optimum strength and ductility were developed for B120VCA titanium, D6AC steel, molybdenum-0.5 titanium to tungsten, and beryllium. Welds were produced in material thicknesses of 0.125 inch for the B120VCA titanium 0.290 inch and 0.090 inch for the D6AC steel 0.100 inch, 0.050 inch, and 0.005 inch for the molybdenum-0.5 titanium welded to tungsten and 0.040 inch for the beryllium. The effects of thermal treatments aging and heat treating were investigated in the B120VCA and D6AC by welding and testing a variety of weldthermal treatment combinations. A comprehensive preliminary welding phase was conducted during which the effects of various welding conditions on weld-zone characteristics were evaluated by visual, radiographic or dye penetrant, and metallographic inspection. Welds were evaluated for extent of fusion, grain size, cracking, porosity, and other pertinent effects.
