Abstract: This friction welding method employs a floating shroud in the tail stock of the welder that provides radial support of a workpiece having thin or fragile portions. There is limited shroud rotation relative to the tail stock during the welding process so that torsional forces generated during friction welding will not be transmitted from the workpieces through the shroud to the tail stock. This allows the workpieces to be joined without destruction or damage by the friction welding process. The shroud has a plurality of segments facilitating easy removal of the workpieces from the tail stock.

Abstract translation: 这种摩擦焊接方法在焊接机的尾料中使用浮动护罩，其提供具有薄或脆弱部分的工件的径向支撑。 在焊接过程中，相对于尾料的护罩旋转受到限制，使得在摩擦焊接期间产生的扭转力将不会从工件通过护罩传递到尾架。 这允许工件被连接而不会被摩擦焊接过程破坏或损坏。 护罩具有多个段，便于从尾料轻松移除工件。
