sulatusliitos

Sulatusliitos, also known as fusion bonding or thermosetting joining, is a welding technique used to join thermoplastic materials. It relies on the application of heat to melt the surfaces of the components to be joined, followed by the application of pressure to fuse them together as they cool. This process creates a strong, monolithic joint that is often as strong as the parent material itself.

The specific method of applying heat varies depending on the type of sulatusliitos. Common techniques include hot gas welding, where a heated gas stream is used to melt the surfaces, and hot plate welding, where a heated metal plate is inserted between the parts. Ultrasonic welding uses high-frequency vibrations to generate heat at the interface, while spin welding employs friction generated by rotating one part against another. Extrusion welding is another method where molten thermoplastic material is extruded onto the joint area.

The success of a sulatusliitos depends on several factors, including the correct selection of materials, proper preparation of the joint surfaces, precise control of temperature and pressure, and adequate cooling time. Contamination of the surfaces can significantly weaken the bond. This joining method is widely used in various industries, including automotive, pipe manufacturing, and the production of plastic components due to its ability to create durable and leak-proof connections.
