    • The present disclosure is directed to methods for joining initially separate members (302', 304') of different metallic materials, e.g., as in joining segments of a multi-segment intravascular guide wire (300'), as well as multi-segment intravascular guide wires (300') so formed. Initially separate members (302', 304') are provided, which members (302', 304') comprise different metallic materials relative to one another, e.g., stainless steel and nitinol. The members (302', 304') are aligned with one another, and a first force is applied to the members (302', 304') while delivering electrical current through the members (302', 304') to solid state weld the separate members (302', 304') to one another. A follow up force that is greater than the first force is applied as solid-state deformation occurs and a weld nugget (322') forms between the members (302', 304'). The weld nugget (322') so formed is thinner and of a larger transverse cross-sectional area than would be produced without application of the follow up force.
    • 本公开涉及用于连接不同金属材料的初始分离的构件(302',304')的方法,例如在多段血管内导丝(300')的接合段中以及多段血管内 如此形成的导丝(300')。 首先提供分离的构件(302',304'),哪些构件(302',304')相对于彼此包括不同的金属材料,例如不锈钢和镍钛诺。 构件(302',304')彼此对准,并且第一力施加到构件(302',304'),同时将电流通过构件(302',304')传递到固态焊接 分离的构件(302',304')彼此。 当发生固态变形时,施加大于第一力的跟随力,并且在构件(302',304')之间形成焊点(322')。 如此形成的焊接块(322')比没有施加后续力而产生的焊接块(322')更薄并且具有较大的横截面面积。
