Aluminium fabrication techniques are essential for creating marine fuel tanks that stand the test of time in harsh marine environments. With aluminium’s natural resistance to corrosion, combined with advanced fabrication methods such as cutting, welding, and surface finishing, these tanks can provide exceptional durability and reliability.

A Quick Look at Aluminium Fabrication

Aluminium fabrication is the process of shaping, cutting, forming, and assembling aluminium into desired structures or components. This process involves a range of techniques to manipulate aluminium, which is a lightweight, corrosion-resistant, and durable material, making it ideal for a wide variety of industries such as construction, aerospace, automotive, and marine.

Ensure the Longevity of Marine Fuel Tanks

Aluminium fabrication techniques for marine fuel tanks are specialised processes designed to create durable, lightweight, and corrosion-resistant tanks for marine applications. The following are the key techniques used in the fabrication of aluminium marine fuel tanks:

•  Cutting and Shaping: Plasma Cutting is commonly used to shape aluminium sheets for fuel tanks. It ensures clean edges and allows for the creation of complex shapes required for custom-designed tanks. For high precision and minimal material waste, waterjet cutting is another technique employed. It uses high-pressure water to cut through the aluminium without generating heat, reducing the risk of warping.

•  Bending and Forming: Press braking uses a press brake machine to bend aluminium sheets into the desired shapes for the tank structure. It’s crucial for forming the curved sides and angles needed in marine fuel tanks. Aluminium sheets can also be rolled to create cylindrical or curved shapes, which are common in marine fuel tank designs. Rolling allows for consistent, smooth curves, which are important for fuel tank efficiency.

•  Welding: TIG (Tungsten Inert Gas) welding is the preferred method for joining aluminium in fuel tank fabrication. It provides strong, clean welds, which are essential for preventing leaks and ensuring structural integrity. Inert gas is used to protect the weld from oxidation during the process. MIG welding is sometimes used for thicker aluminium components. Like TIG welding, it uses an inert gas to prevent oxidation but is faster, making it suitable for larger tank sections.

•  Surface Preparation and Treatment: After cutting and welding, the aluminium edges are deburred to remove sharp edges and prevent any potential for leaks or structural weaknesses. Aluminium fuel tanks may likewise undergo anodising to enhance corrosion resistance. This electrochemical process thickens the natural oxide layer on the aluminium surface, offering better protection against seawater and fuel.

•  Leak Testing: After fabrication, tanks are pressure-tested to ensure they are leak-proof. This step is critical in ensuring that the tank can safely contain fuel without the risk of spillage.
