The plates that are to be joined are brought face to face such that an overlap exists, as
shown in figure 10.1.3. Rivets are inserted on the overlapping portion. Single or multiple
rows of rivets are used to give strength to the joint. Depending upon the number of rows the
riveted joints may be classified as single riveted lap joint, double or triple riveted lap joint
etc. When multiple joints are used, the arrangement of rivets between two neighbouring rows
may be of two kinds. In chain riveting the adjacent rows have rivets in the same transverse
line. In zig-zag riveting, on the other hand, the adjacent rows of rivets are staggered.
