Title
(EN) AUTOGENOUS SUBMERGED LIQUID DIFFUSION WELDING OF TITANIUM
(FR) SOUDAGE DE TITANE PAR DIFFUSION DE LIQUIDE SUBMERGÉ AUTOGÈNE
Abstract
(EN)
In some embodiments, a method may bond titanium to an intermediate alloy. The method may include layering a portion of an intermediate alloy onto a portion of titanium. The method may include focusing a controlled heat source on a spot of the intermediate alloy to form a weld pool in the intermediate alloy at the spot. The method may include superheating the intermediate alloy in the weld pool above the melting point of the intermediate alloy but below the melting point of titanium such that liquid intermediate alloy contacts the surface of the portion of the titanium heating the portion of the titanium. The method may include diffusing the portions of titanium and intermediate alloy together such that upon the intermediate alloy cooling below the melting point of the intermediate alloy the portions of the intermediate alloy and titanium are bonded forming a weldment.

L'invention concerne, selon certains modes de réalisation, un procédé qui peut lier du titane à un alliage intermédiaire. Le procédé peut comprendre la stratification d'une partie d'un alliage intermédiaire sur une partie de titane. Le procédé peut comprendre la focalisation d'une source de chaleur commandée sur un point de l'alliage intermédiaire pour former un bain de soudure dans l'alliage intermédiaire au niveau du point. Le procédé peut comprendre la surchauffe de l'alliage intermédiaire dans le bain de soudure au-dessus du point de fusion de l'alliage intermédiaire mais au-dessous du point de fusion du titane de sorte que l'alliage intermédiaire liquide entre en contact avec la surface de la partie du titane chauffant la partie du titane. Le procédé peut comprendre la diffusion des parties de titane et d'alliage intermédiaire l'une avec l'autre de telle sorte que, lors du refroidissement de l'alliage intermédiaire au-dessous du point de fusion de l'alliage intermédiaire, les parties de l'alliage intermédiaire et du titane sont liées et forment un ensemble soudé.
