    • The invention relates to a method for joining at least two aircraft fuselage segments (2, 3) by friction stir welding with a tool (8) generating friction heat for the partial plasticisation of an edge region (6, 7) of at least one of the two aircraft fuselage segments and a counter bearing (10) for absorbing the force exerted by the tool (8) on at least one of the two aircraft fuselage segments, wherein at least one of the two aircraft fuselage segments comprises at least one rib (17) and/or one stringer (16).In order to minimise the necessary expense incurred in association with the production aids for the FSW process, it is proposed that the at least one rib (17) and/or the at least one stringer (16) of the at least one aircraft fuselage segment (2, 3) should be used as a counter bearing (10).
    • 本发明涉及通过摩擦搅拌焊接与至少两个飞行器机身段(2,3)之间的至少一个的工件(8)接合至少两个飞行器机身段(2)的方法,所述工具(8)产生摩擦热,用于部分塑化边缘区域 所述两个飞行器机身段和用于吸收由所述工具(8)施加在所述两个飞行器机身段中的至少一个上的力的反向轴承(10),其中所述两个飞行器机身段中的至少一个包括至少一个肋( 17)和/或一个纵梁(16)。 为了最小化与FSW过程的生产助剂相关联的必要费用,建议至少一个飞行器机身段的至少一个肋(17)和/或至少一个纵梁(16) (2,3)应用作反轴承(10)。
