Information You Can Take Notes Of In TIG Welding Aluminum

By Brenda Gibson


Creating objects out of raw materials have been observed since time immemorial. The beginning of the industrial revolution saw the rise of crafting metals to useful household and manufacturing items. An engineer knows that in TIG welding aluminum is one of the easy materials to bend.

High temperatures are used in welding so metals can be bended, shaped, and cut into a certain design. The design of these items may be innovative and new for everyday use. Two separate pieces are being connected due to this. The particle structure of the metal rearranges through the application of high heat making it easier to handle and form.

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.

Like any method, this uses a machine which they can easily manage when doing the process. They fill in the rod into the electric torch. Inside the torch are the collet holder, collet and tungsten. The holder has a tiny hole to allow the gas to surround the tungsten so contamination is prevented.

Like steel, gold, and copper, one of the great conductors of heat is aluminum. The household items, cars and other transportation, and phones have aluminum crafted into them. Manufacturers prefer to use it because it is light and durable. It also is naturally resistant to corrosion. The reason behind this is because of its oxide layer it has which is thin yet strong.

The layer of oxide must first be removed before starting the welding process. Doing so would make welding it easier to shape by welder without sacrificing the metal quality. The reason they do this is because aluminum is a type of metal that does not show in its surface if it is ready enough or hot enough to be welded. Burnt spots do not occur on its surface unlike most metals.

They also clean the surface of its pieces or the entire surface before welding. This is to ensure that no compounds will create any damages on its surface. If it does, it will have a direct effect on the quality of their welded object.

Oxygen and hydrogen are those compounds. An oxide reaction on the metal produces dross along its sides, or solid mass of wastes. The presence of pores or tiny holes in its surface is the effect of hydrogen which will make water and liquid solutions 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.
