The Importance of Jointing Techniques

Civil engineers use different methods to connect materials. Mechanical fixings such as bolts, screws and rivets are popular because they allow components to be removed when repairs are required. Non-mechanical methods such as welding and adhesive bonding often provide strong permanent joints. However, environmental conditions may affect some connections. For example, vibration can loosen mechanical fixings, while excessive heat can weaken certain adhesives. Engineers must therefore consider future maintenance, operating conditions and safety requirements before selecting a jointing method.
