Which joining method is categorized as a temporary joining process?

Nuts and bolts are considered a temporary joining process because they can be easily removed and reassembled. This makes them ideal for applications where adjustment, maintenance, or disassembly is required. For instance, in the construction of metal structures, the ability to take apart components without damaging them is essential for repairs or modifications.

In contrast, other methods like pop riveting and adhesives create permanent bonds that are not intended to be undone easily. Soldering, typically used in electronics, also creates a permanent connection between components. Thus, nuts and bolts stand out as a versatile and temporary option, allowing for flexibility in design and maintenance.
