What is a disadvantage of permanent joints?

Permanent joints are designed to create a lasting bond between components, which means they are not intended to be disassembled once they are made. This characteristic makes them less flexible in situations where maintenance or repair is necessary. If a component needs to be accessed or replaced, a permanent joint can complicate the process, potentially leading to increased downtime and costs associated with damage or required cutting to separate the parts.

In contrast, temporary joints are specifically designed to be reassembled, allowing for easier maintenance and adjustments. This makes them more suitable for applications where components need to be frequently serviced or replaced. Therefore, the inability to take permanent joints apart for maintenance is a significant disadvantage that should be considered during the design phase of engineering projects.
