What type of connection does a 'welded joint' create?

A welded joint creates a permanent connection between two or more pieces of metal or piping. The process of welding involves melting the base materials and adding a filler material to form a strong bond as it cools and solidifies. This results in a joint that cannot be easily disassembled or removed without cutting or damaging the welded sections.

Welded joints are essential in applications where strength and integrity are critical, such as in pressure vessels, structural steelwork, and piping systems. They are preferred when a robust, leak-proof seal is required. The permanence of welded joints helps to ensure the reliability of the system, particularly in high-stress environments where movement, vibration, or pressure could compromise loosened or temporary connections.
