Metallförsegling

Metallförsegling is a term referring to the process or result of creating a seal using metal. This technique is employed in various industries to ensure the integrity and containment of products or systems. The primary function of a metal seal is to prevent leakage of substances, such as gases or liquids, or to protect contents from external contaminants. The choice of metal and the specific sealing method depends heavily on the application's requirements, including the operating temperature, pressure, chemical environment, and the need for long-term durability.

Common methods for metallförsegling include welding, brazing, soldering, and the use of metal gaskets or O-rings. Welded seals are often permanent and robust, creating a molecular bond between metal components. Brazing and soldering involve using a filler metal to join two pieces of metal at a lower temperature than welding, still forming a strong joint. Gaskets and O-rings made from metal, or incorporating metallic components, are often used in flange connections or mechanical seals to provide a deformable barrier that conforms to mating surfaces. These seals are critical in applications ranging from automotive engines and pipelines to aerospace components and vacuum systems, where reliability and containment are paramount.
