Aluminium welded pipes are generally fabricated using alloys such as 6061, 6063, and 5083, which offer a satisfactory combination of strength, corrosion resistance, and weldability. The welding operation entails the joining of aluminium strips or sheets along a longitudinal seam to produce a robust, rigid pipe with consistent mechanical properties. The pipes have high thermal and electrical conductivity, medium to high tensile strength, and resistance to weathering and corrosion. The aluminium welded pipes are structurally rigid but very light in weight, with ease in handling and installation. They may also be anodized or coated for enhanced surface protection and beauty.
