What is riveting?

Riveting refers to a mechanical fastening process that uses a metal pin or bolt to join two or more pieces of material together, typically in a permanent manner. This process involves inserting the rivet into pre-drilled holes in the materials to be joined, and then deforming the end of the rivet to secure it in place. The strength and durability of riveted joints make them ideal for applications in construction, metalworking, and manufacturing, especially where welded joints may not be appropriate for structural reasons.

While the other options describe different techniques used in metalworking, they do not accurately represent riveting. For instance, bonding using heat describes welding rather than riveting. Decorative metalworking involves aesthetic enhancements rather than structural joining. Similarly, welding is a different method of joining materials through melting, not the mechanical fastening approach that riveting employs. Thus, the focus on a metal pin or bolt clearly defines riveting as a specific and recognized method of joining materials.
