Explain the engineering term permanent joint. - Leaving Cert Engineering - Question (b) - 2021

A permanent joint refers to a type of connection between two components that cannot be disassembled without causing damage to the joint or the materials being joined. This means that the assembly is intended to be a long-lasting, fixed relationship between parts.

Examples include:

• Pop Rivets: These are commonly used in structural applications where the joint needs to withstand forces without being easily taken apart. When installed, they create a secure bond that doesn't allow for disassembly without cutting or destroying the rivet itself.
• Welding: This involves melting and fusing materials together, creating a joint that is often stronger than the materials themselves but irreversible.

In summary, a permanent joint is an essential aspect of construction and manufacturing where a robust and durable connection is required.
