TIG Welding Aluminum Facts To Know

By Brenda Gibson


Ever since, objects are created through the use of materials found in the surroundings. Manufacturing objects electronically started during the heights of the industrial revolution. Most items for everyday use are produced through this. One method in producing these items is through TIG welding aluminum.

Metals are shaped, cut, and bended due to the high heat temperatures applied on it during welding. Two separate pieces of metal are getting connected in order to produce the object designed. The structure of particles inside them is being rearranged due to the heat so people can form and handle them with ease.

Also known as gas tungsten arc welding, this tungsten inert gas welding is one of the methods being applied by technicians and engineers. Here, the weld is being produced by using a non consumable tungsten electrode. This electrode can be a rod or wire piece which carries the electric current needed to weld the metal.

There are machines for these people to use in welding materials. An electric torch is attached to it through a wire wherein a rod is placed inside it. The torch is composed of tungsten, collet holder and collet inside. The tiny hole is placed on the holder to let the gas surround the tungsten to help in preventing contamination.

Aluminum is one metal type that is a great conductor of heat along with copper, steel, and gold. This metal is preferred in crafting phones, household items, cars and other modes of transportation because of its light and durable features. They also like to use this because of its natural resistance to corrosion. This is due to its surface being covered in a thin yet strong layer of oxide.

However, the oxide layer has to be removed before they can start the process. Its removal would make their job easier in its entirety. They also do not have to sacrifice the quality of its metal surface. They do this because it has not outward indication if it is ready and hot enough to melt. No burnt spots can be seen on it unlike most metals.

Cleaning the entire metal or its cut pieces is an action they are required to do. There may be compounds on it which will damage its surface. Leaving them there would surely affect the quality of the product by the time it is finished.

The compounds are hydrogen and oxygen. The presence of oxygen will produce dross, or a mass of solid waste, along the sides of the welded surface. Tiny pores or holes will form on its surface due to the presence of hydrogen which will allow liquid solutions and water to pass through.

When it comes to the oil they use, and the dust and moisture that occur during the process, they have ways to clean its surface. They use either of these ways on it. One option is that they use an alkaline solution which is mild on it and then they left it to dry. Another is using acetone or alcohol solution. Or, they use a denatured alcohol solvent.
