The joint efficiency of riveted joi

The joint efficiency of riveted joints vary,depending on the rivet diameter,the spacing,etc.,and it is never possible to obtian 100% joint efficiency.
Water and air tightness.It is very difficult to maintain complete water and air tightness in a bolted or riveted structure during service,but a welded structure is ideal for structurs which require water are air tightness such as submarine hulls and storage tanks.

铆接接头的联合效率而异，铆钉直径、 间距等，也并不可能沟通和联合效率为 100%。水和气密性。它是很难保持完整的水和气密性，在螺栓或铆接结构在服务，但焊接的结构是理想的因为需要水的优越性是潜艇船体和储罐的气密性。
