Abstract
A method for producing a weldable titanium alloy and/or composite wire. The method includes: a) forming a green object by blending particulates of titanium sponge with one or more powdered alloying additions and cold compacting the blended mixture and subjecting the blended mixture including lubricant to pressure; b) forming a work body of alloyed titanium by heating the green object in a protected atmosphere and holding the temperature for a period of at least 4 hours, and then hot working the green object at a temperature of less than 200° C. apart from the beta transition temperature of the titanium alloy and shaping the green object to obtain an elongated profile; and c) forming the welding wire by placing the elongated profile of the work body in a rolling mill having one or more rolls disposed in series.
