Liidestust

Liidestust is an Estonian term used to describe the process of joining two or more components to form a single, continuous assembly. It encompasses both mechanical joining methods and bonding techniques that create a functional connection without requiring full material fusion. In engineering practice, liidestust is evaluated for joint strength, durability, and compatibility of the joined parts.

Common liidestust methods include mechanical fastening (bolts, screws, rivets), welding (fusion of metal parts), soldering and brazing (joining with a filler metal at elevated temperature), and adhesive bonding (epoxies, acrylics, polyurethanes). Each method has distinct advantages and limitations regarding load transfer, environmental resistance, and manufacturability. Surface preparation, cleanliness, and the presence of coatings significantly influence joint performance.

Material compatibility is crucial: differences in strength, thermal expansion, and corrosion potential must be managed to prevent premature failure. Joint design considers load paths, geometry, and protection from mechanical wear. Quality control often uses tests such as tensile or shear tests, nondestructive testing, and inspection of joint geometry and surface condition.

Liidestust is used across industries, including automotive, construction, electronics packaging, and metal fabrication, to connect components ranging from structural beams to circuit-board connectors. Safety and environmental considerations include fume control during welding, ventilation for adhesives, and proper disposal of waste and adhesives. Terminology and standards vary by field; practitioners refer to established engineering codes for specific joining methods.
