8. Riveting faults

- If the rivet shank is too long. the superfluous material forms a wreath at the head of the closing head.

Figure 33 - Riveting faults

- If the rivet shank is too short, the closing head is not sufficiently formed,

Figure 34 - Riveting faults

- If the plates are not enough tightened by the rivet setter, the shank is squeezed between the plates, a wreath appears and the closing head is not correctly formed.

Figure 35 - Riveting faults

- If the hammer blows on the rivet setter are too strong, the upper plate is squeezed too much and bows.

Figure 36 - Riveting faults

- If the bore holes are heavily misaligned, the rivet shank will be notched, so that the rivet cannot stand high shearing loads.

Figure 37 - Riveting faults

- If the rivet hole is too large, the rivet shank bends, the closing head is not formed.

Note:

Use the corresponding rivet setter and rivet header for the rivet you have chosen,
