Abstract:

Techniques for the high-voltage electron beam welding of pure W and arc-cast Mo-0.5 Ti were developed and evaluated. Welds were produced in sheet thicknesses of 0.005, 0.050, and 0.100 in. for each material. Primary emphasis was placed on producing butt welds of maximum strength and ductility. Limited work was performed on lap, seam, edge, and spot welding. The effects of various welding conditions on weld-zone characteristics were evaluated by visual, radiographic, fluorescent penetrant, and metallographic inspection. Welds were inspected for extent of fusion and recrystallization, grain size, cracking, porosity, and other pertinent effects. Butt welds of each thickness exhibiting optimum weldzone characteristics were evaluated for mechanical properties. Weld ductilities were determined by transverse bend testing at temperatures to 1200 F. Weld tensile properties were determined at room temperature and at temperatures to 2800 F. Author
