Abstract
A method and structure for welding an air-sensitive metal, such as titanium, in an ambient environment containing air. The method () includes forming a weld () through a weld-through coating () applied to the weld face(s) () and heat-affected zone () of one or more workpiece(s) () to be welded. The weld-through coating may contain a reactive material that comprises one or more halogenides of alkali metal, e.g., fluorides of barium, calcium, and strontium. The weld-through coating may be applied to the workpiece using a thermal-spray process, such as a plasma-spray process (), prior to forming the weld. The weld-through coating may be applied to the workpiece(s) generally contemporaneously with the formation of the weld just ahead of the weld or may be applied at any time prior to forming the weld.
