Niittausmenetelmät

Niittausmenetelmät refers to a group of joining techniques used to fasten two or more parts together using rivets. These methods are fundamental in manufacturing and construction, offering a strong and permanent connection. The core principle involves inserting a rivet through aligned holes in the parts to be joined and then deforming the rivet's tail to create a second head, effectively locking the parts together.

Different niittausmenetelmät exist, categorized by the type of rivet used and the application method. Common types include solid rivets, which are typically used in high-stress applications like aircraft structures and bridges. These require more force to set and are often installed using hammering or specialized pneumatic tools. Tubular or semi-tubular rivets are also prevalent, offering a lighter and easier installation process, suitable for less demanding applications. Rivet guns, both manual and powered, are employed to drive and deform the rivets. Blind rivets, also known as pop rivets, are a specialized category designed for situations where access to both sides of the joint is limited. They consist of a rivet body and a mandrel, which is pulled through the body to deform its blind end.

The choice of niittausmenetelmä depends on factors such as the materials being joined, the required strength of the joint, the accessibility of the work area, and the production volume. Each method provides a distinct advantage, contributing to the versatility and reliability of riveting as a joining process.
