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

A permanent joint refers to a joining method that establishes a connection which will not be disassembled or come apart again after being created. This means that once a permanent joint is made, the components involved cannot be easily separated without damaging them.

Common examples of permanent joints include:

• Welding: A process that fuses materials together, typically metals, by melting them at the joint.
• Adhesives: Substances used to bond materials together, like glue, that set to create an inseparable bond.
• Soldering: A technique often used in electronics where a filler metal is melted to join two workpieces.

These methods are integral in many manufacturing and construction applications, providing strong, durable connections.
