Metals are immensely beneficial for multiple purposes. No matter if you’re setting up your industry or building your home, metals have a huge role to play. However, it is important to know which form of welding or fabrication is used with which metal. The correct pairing of the two can be extremely effective wherever it is applied. Aluminum conductors are also in huge demand.
In the world of metal, Aluminum has a unique culture. Despite being in high demand, this metal is difficult to weld. This has led to the increase in experimentation with the metal so as to make most of its unique qualities. This is also one of the reasons why welders need to have prior training.
Properties of aluminum
Until this metal was discovered, the world suffered from a lot of issues, mainly low strength and formation of corrosion. The discovery of this unique metal has changed their lives forever. Aluminum is lightweight, strong, and is versatile. These indispensable qualities have made the metal highly cost-effective at the same time.
Despite having such amazing properties, it is a tricky job to weld this metal. This is mainly because the metal has a low melting point. When this attribute is paired with the ability of this metal to conduct heat, it becomes a big problem, especially when working with aluminum sheets.
Unlike other metals, welded aluminum is weaker than the parent metal. This is because aluminum normally conducts heat during the welding procedure. To treat this issue, the metal is hardened by a technique known as cold working. This makes the welded and treated metal less strong than the parent metal. Therefore it is necessary to conduct heat treatments after welding so as to retrieve some of the lost properties of the metal. Nirmal Group is one of the main GI fencing wire manufacturers of Kolkata pay special attention to this issue.
Methods of Welding Aluminum
Nirmal Group, which is one of the main steel pipes manufacturer effectively deals with this issue by opting for renowned techniques to weld aluminum. Gas Tungsten Arc Welding, also known as Tungsten Inert Gas (TIG), is one of the most renowned processes of aluminum welding. In this method, a non-consumable tungsten electrode is used. Inert gases such as helium or argon are also used. These gases are used to prevent the metal from oxidation. This procedure is known as the cleanest technique and does not need wire filler materials. However, due to the complicacy of the method, it is essential to recruit a professional person.
Gas Metal Arc Welding, also known as Metal Inert Gas (MIG), is another popular method of welding aluminum. This method was developed in the 1940s and was especially used to treat non-ferrous metals and aluminum. In this method, an electric arc is used between the aluminum piece and a consumable MIG wire electrode. To prevent contamination, a preventative gas is passed through the welding gun.
Precautions to be Taken During Aluminum Welding
Welding is a dangerous process and therefore requires safety before all else. It is essential to use safety precautions and use special equipment. Protective things such as welding masks, thick hand gloves, welding boots and leather smocks should be possessed by each technician at work.
Another thing to consider while working at a welding factory is to handle hot metals after cooling. Mishandling of warm metals may cause accidents and injuries. You will also need to make sure to use a respirator if you’re working at this place for a long period of time. This is because most metals release toxic fumes which are extremely harmful to the body. Due to these reasons, Nirmal Group prefers using professionals for this job.
