1. Types and Meaning of Permanent Joints

Permanent joints are engineering joints of two or more parts (components, conductors) and are made by joining,

- Permanent joints are used to join (connect) materials.

- Permanent joints must withstand the same mechanical and electrical stress as the materials to be joined.

- Permanent joints can only be detached by destruction of the joining elements or of the parts joined.
