Aluminium fabrication works involve a variety of techniques to manipulate the metal into specific shapes and sizes for various applications. With its lightweight, durable, and versatile nature, aluminium is widely used in industries ranging from construction to automotive. To achieve the desired results, fabricators must master several essential techniques, including:
Cutting:
Cutting is one of the most fundamental techniques in aluminium fabrication works. Depending on the thickness and the shape of the material, several cutting methods can be used, such as sawing, shearing, or laser cutting. For intricate or complex shapes, laser cutting offers precision and clean edges, while sawing is ideal for straight cuts in thicker aluminium sheets. The choice of cutting method depends on the project requirements, with precision being a key factor for many applications.
Bending:
Bending involves the deformation of aluminium into a desired angle or curve. This technique is commonly used to create brackets, frames, and other structural components. Bending is typically done using press brakes, which allow fabricators to apply controlled force to the material. The ability to bend aluminium without causing cracks or fractures requires careful control of the bending machine and an understanding of the material’s properties.
Welding:
Welding is an important technique for joining aluminium components together. Since aluminium has a lower melting point than steel, special considerations are needed to avoid distortion or burn-through. MIG (Metal Inert Gas) welding and TIG (Tungsten Inert Gas) welding are the most common methods used for aluminium. MIG welding is typically used for thicker materials, while TIG welding is preferred for more precise, high-quality welds, particularly in thin aluminium sections.
Riveting:
Riveting is a technique used to permanently join two pieces of aluminium together by inserting a metal pin (the rivet) through pre-drilled holes in the materials. The rivet is then deformed to hold the pieces in place. This method is often used in aircraft and automotive manufacturing, as it provides a strong, secure joint without the need for heat. Riveting is particularly useful for joining materials in situations where welding may not be feasible.
Stamping:
Stamping is a high-volume technique used to create intricate shapes or designs in aluminium sheets. It involves placing the aluminium in a die and using pressure to form the material into the desired shape. Stamping is commonly used in the production of automotive body panels, appliances, and electronics. This technique is ideal for creating precise, repetitive shapes in thin sheets of aluminium.
