Aluminum Welding for Storage Tanks

Advantages

• High Weld Strength: Provides weld deposits that exceed the required tensile and yield strength for safe pressure containment applications.

• Cryogenic Suitability: Specific alloys (like ER5183) maintain excellent ductility and fracture toughness down to cryogenic temperatures, essential for LNG tanks.

• SCC Resistance: Controlled elemental composition reduces the susceptibility to stress corrosion cracking, enhancing the longevity of the tank structure.

• Smooth Feeding: The precise cleaning and spooling of the wire facilitate long, continuous welds with minimal interruption, increasing site productivity.

FAQ

• Q: Which filler metal is required for ASME code pressure vessel welding?
• A: The specific filler metal depends on the base metal (e.g., 5083 requires ER5183 or ER5356), but the wire must be manufactured under a strict quality system to comply with Section IX material certification requirements.

• Q: Can these wires handle the cyclic loading experienced by transport tankers?
• A: Yes, the high ductility and fatigue resistance of our 5XXX series weldments are specifically suited to handle the constant sloshing and vibration forces in transportation and mobile storage tanks.
