(in Russian, klepka) the process of joining structural components with rivets, forming a nondetachable riveted joint. In a riveted joint no corrosion occurs and no voltaic couples or similar processes are present; therefore, the strength and reliability of the joint remain unchanged over long periods of time. The most common type of riveting uses rivets with countersunk heads, producing a smooth surface of the workpiece. Button-head rivets are used to join components where there are no stringent requirements for appearance and smoothness of the articles.
Riveting consists of the following operations: drilling or punching of rivet holes; formation of a recess for countersunk rivet heads (by countersinking or punching); insertion of the rivet, which consists of a primary head and a shank; and formation of a closing head by means of a riveting die and a riveting dolly. The closing head may be formed by pressing (pressure riveting) or by impact (impact riveting). Pressure riveting is performed on riveting machines (riveting presses or automatic riveters); impact riveting is done with riveting hammers. Riveting is used in fabricating various metal structures in shipbuilding and production of railroad cars and aircraft.
The Russian term klepka is also used for lumber in the form of narrow boards (clapboards or staves).
