Riveting is a mechanical process used to join two or more pieces of material, typically metal, by inserting a metal pin called a rivet. The rivet is heated and then deformed to create a strong bond between the materials. This technique is commonly used in construction, manufacturing, and shipbuilding due to its durability and strength. The process of riveting can be performed using various tools, including hammers, riveting machines, and pneumatic tools. Riveting is often preferred over welding in certain applications because it can be more effective in joining dissimilar materials and is less affected by heat distortion.
