摘要:  A method of joining, e.g., by fusion welding, titanium, and titanium-based alloys to ferrous metals, and the intermetallic weld pool created by practice of the method is described. The instant invention involves the use, inclusion or deployment of tantalum into the weld pool and upon cooling a weld, to create a surprisingly strong intermetallic bond, weld, or joint.
主权项:  A method of joining titanium, or a titanium-based alloy, to a ferrous metal to produce a strong ductile weld, comprising the steps of: a) providing a tantalum joint precursor extending along a longitudinal axis, wherein the tantalum joint precursor has an outer face aligned substantially perpendicular to the axis; b) providing a ferrous metal coil extending from a proximal coil end to a distal coil end, and placing the proximal coil end of the ferrous metal in close proximity to the outer face of the tantalum joint precursor; c) providing at least one titanium or titanium-based alloy workpiece extending from a titanium workpiece proximal end to a titanium workpiece distal end, and placing the proximal end of the at least one titanium or titanium-based alloy workpiece in close proximity to the outer face of the tantalum joint precursor, d) wherein, with respect to the longitudinal axis, the titanium or titanium-based alloy workpiece resides radially inside the ferrous metal coil; e) fusion welding the tantalum joint precursor thereby producing a weld pool incorporating the proximal end of the at least one titanium, or titanium-based alloy workpiece, and the proximal end of the ferrous metal coil, and a portion of the outer face of the tantalum joint precursor; and f) permitting the weld pool to cool and form a weld connected to the titanium or titanium-based alloy workpiece and the ferrous metal coil, g) wherein the titanium or titanium-based alloy workpiece and the ferrous metal coil extend away from the tantalum in the same axial direction.
