Permanent Joint


a joint that provides a rigid mechanical connection of parts in an assembly of a machine throughout the period of use. A permanent joint usually cannot be disassembled without destroying the parts or damaging their surfaces. The

main types of permanent joints are riveted, welded, soldered, pressed, cemented, rolled, and combined (such as cemented and welded). The choice of type of a permanent joint is determined by the requirements of manufacture, assembly, and operation of the machine and by economic considerations.
