Abstract: Tenons can be installed at the ends of turbine blades by applying a solid state bonding procedure such as a friction welding technique to join the tenons to the turbine blades. The tenons can be employed to assemble the turbine blades to one or more covers for the turbine blades. The tenons can be installed in connection with the restoration of tenons for turbine buckets in steam turbines and in connection with the renovation of rotor assemblies that include turbine blades secured to a common disk, tenons located at one end of respective turbine blades and one or more covers secured to the turbine blades by means of the tenons. In instances in which tenon remnants are present at the ends of the turbine blades, tenon enlargement elements can be joined to the tenon remnants by the solid state bonding procedure. The tenon installations can be carried out in situ.

Abstract translation: 通过施加诸如摩擦焊接技术的固态粘合方法将榫头安装在涡轮机叶片的端部，以将榫头连接到涡轮机叶片。 榫头可用于将涡轮机叶片组装到用于涡轮机叶片的一个或多个盖子。 榫头可以安装在蒸汽涡轮机中用于涡轮机桶的榫头的修复，并且与包括固定到公共盘的涡轮机叶片的转子组件的改造相关联，并且位于相应涡轮机叶片的一端的榫头和一个或多个 通过榫头固定到涡轮叶片的盖子。 在涡轮叶片的端部存在榫头残余物的情况下，通过固态接合程序可以将榫头放大元件连接到榫头残余物。 榫头安装可以在原地进行。
