Some Necessary Tips – TIG Welders

TIG refers to Tungsten inert gases and in this process the different types of reactive gases like magnesium and aluminum are blended together. The method was devised during the 1940’s and soon became popular after that. Today it is used for aluminum welding and other structural processes. Today the process is used for manual and high quality welding in the types of welding used today.

In the TIG welding process, an arc is made from the pointed tungsten electrode to the area that is to be welded. This in the process shields the gas which prevents oxidization of the welded material and thus gives quite a clean weld.

The different gases that are used for the process of TIG welding are helium, argon or sometimes combination of both. When single gas is used for the process of TIG welding Argon is generally preferred as they it is heavier than air and provides a better area for coverage. The combination method renders better welding speed and surface penetration.

TIG welding is performed in different types of materials. Some of the most common types of materials used are aluminum and steel. The filter rods are also welded through this process. They generally use the same material that is used for the base metals. The process is appropriate for welding heavy metals, steel fabrication and reinforcing joints.

The Different Types of TIG Welding

There are many different types of joints that are fused using TIG welding process. This includes lap joint, butt joint, t-joint and corner joint. The butt joints are fused by using filter rods. Here the two metals are molded with each other using the seam line.

The other process is lap joint where the top edges of the metals are welded with the bottom piece and are seamed in the area of their overlapping metals. In the corner joint process, one strap of metal is fused with another piece of metal at right angle to each other set in the corner and hence is called corner joint. In the t-joint process one piece of metal is set in perpendicular to the other piece of metal such that it gets a t-shape.
