WELDING OF REFRACTORY METALS

Abstract

Effort was directed toward an establishment of weld parameters for the inert gas non-consumable electrode welding and the evaluation of the effect of restraint using various combinations of parameters. This basic information was used to establish general procedures for autogeneous butt welds (0.035in thick), for multipass butt welds (0.125in. thick) and for manual fillet welds (emphasizing full penetration and contact of the low side contour in the down hand vertical overhead position). Qualifying the above procedures in the InFab environment using bend ductility, penetrant inspection radiography and tensile tests as criteria was initiated. Four structural alloys of refractory metals were investigated. These are: TZM, B-66, 90Ta-10W and W.
