Explain the term permanent joint. - Leaving Cert Engineering - Question b - 2014

A permanent joint refers to a method of joining materials that cannot be separated without damaging them. This type of joint is created using techniques that ensure the components are fused together in such a way that they become a single, inseparable unit.

Examples of permanent joints include:

1. Welding: A process where two or more pieces of metal are joined together by melting the edges and allowing them to cool, forming a strong bond.
2. Adhesive bonding: Using a strong adhesive that cures and creates a lasting bond between surfaces.
3. Soldering: A process often used in electronics, where a filler material is melted and applied to join electronic components, creating a solid connection once cooled.

These methods ensure that once the joint is made, it will not come apart again, providing structural integrity and strength to the assembled components.
