What Is Aluminum Fabrication?
Metal fabrication is a common speciality in many factories and manufacturing plants; nevertheless, the technique for fabricating aluminium may vary from that of most other metals. Extrusion is a common technique in aluminium fabrication, which allows for the creation of shaped products from aluminium blanks by drawing or pushing them through a die.
This process is different from that of other metals. There are two ways to conduct extrusion: either by heating the metal to make it more pliable, or by leaving it at room temperature.
Lightweight and corrosion-resistant, aluminium finds utility in many different contexts; nonetheless, it is a fragile metal that can shatter under specific stresses. Because it typically applies less stress to the metal during fabrication than other methods, extrusion is an advantageous technique for fabricating aluminium because it reduces the likelihood that the metal will lose its strength. Other manufacturing procedures can also be used to make aluminium, although they may cause the metal to become more brittle due to the increased stress.
Cutting, grinding, drilling, or shaping aluminium into desired shapes follows the transformation of raw materials. A wide variety of products and construction materials rely on aluminium, including window frames, vehicle and bicycle parts, and shuttering formwork. Aluminium is a handy material for building due to its ease of cutting and shaping.
It all depends on the application, but aluminum's lower heat conductivity compared to other metals is definitely a plus. Its low density makes it ideal for high-performance automobiles, but prolonged exposure to high temperatures can cause it to attach to steel, which could damage some parts of the vehicle. Even if they aren't the most long-lasting material, aluminium performance wheels can save weight and increase performance for your car.
How To Fabricate Aluminum
The end-use plans, part size, and complexity of the intended part dictate the proper aluminium production technology. A variety of aluminium fabrication procedures are available, but the most popular ones involve cutting, welding, shaping, and hole creating to produce the final product. These methods of fabrication include:
Forming
Aluminium can be bent, rolled, or stamped into certain shapes during the forming process. When working with aluminium, a bending machine and a stamping press machine are both utilised to achieve precise shaping.
Welding
The process of welding entails melting and joining aluminium parts according to a specified pattern using a welding flame. When working with aluminium, a variety of welding techniques are available. Among these approaches are:
- Stick welding—Electrodes are utilised in this common welding procedure for various materials, including aluminium, although it is not commonly employed for this material. A weld pool is formed when the electrode and the aluminium components are heated together using a welding torch. The molten pool creates a strong bond between metals after it cools. Stick welding is the simplest and most traditional method of joining metal parts, making it ideal for use in the field for repairs. The portability and ability to utilise a stick welder in windy conditions are the main reasons for this. Joints or several pieces of aluminium can be joined using it.
- Welding with metal inert gas (MIG) requires a spool gun for the weld to be laid. To prevent oxidation of the welded area, the spool gun extrudes an electrode and releases a shielding gas onto the joint. The weld's precision and integrity are jeopardised when oxidation or other polluting gases are present.
- The term "tungsten inert gas" (TIG) refers to a type of welding that uses an electrode made of non-consumable tungsten. Tungsten and a filler material are heated together to form the weld in this process. Because the operator has complete command over TIG, it consistently produces the cleanest weld surface area.
Cutting
A lathe or CNC machine is used to cut the aluminium piece during the cutting process. A cutting tool is attached to the machine. Skilled fabricators often opt for cutting techniques developed for aluminium, such as:
- An industrialised shearing tool is used to cut the aluminium component in water jet shearing. To cut through aluminium, the tool uses abrasive material mixed with high-pressure water jets. When compared to other heat-related cutting methods, such as welding, water jet shearing produces a cleaner and more accurate cut.
- A laser cutting machine is used to shape aluminium components by slicing them into the required dimensions. In order to fabricate aluminium in the appropriate patterns, laser machines use the design or shapes from CAD models. The low energy consumption, smooth cuts, and removal of contamination of the aluminium component make laser cutting a common procedure.
- Cutting aluminium with a plasma cutter is one method of plasma cutting. Cutting through aluminium at high speeds with hot plasma jets eliminates the risk of contamination. Cutting using plasma is fast and very efficient. The machine can also carve designs into aluminium using CAD models.
Hole Making
Holes of different lengths and sizes may be necessary for manufactured components based on their specifications. Aluminium fabrication may incorporate these holed patterns using a variety of methods, each tailored to the specific dimensions of the hole. Among these methods for creating holes are:
- To drill a hole, one uses a drill bit to carve out a circular opening. Typically, a workpiece is pushed against a rotating drill bit. Additional fine-tuning may be necessary to ensure that the drilled hole meets the specified dimensions.
- Following the drilling of a hole into the workpiece, the next step is the boring of the hole. A boring tool is used in this process. With each revolution, a tiny amount of metal is injected into the workpiece by means of the rotating boring tool. To get exact measurements that match your design requirements, hole boring is the way to go.
- Tapping entails cutting threads within a hole in preparation for threading a cap screw or bolt into the hole. Lathes, mills, tapping machines, or even just your hands will accomplish the trick. Threading nuts is another possible application of the method. A tap, which is a type of cutting tool, is used to create thread. Its cutting edges resemble threads. Screwing the tap into the hole eliminates superfluous metal and cuts the internal thread.
Industrial applications
