TIG Welding

Tungsten inert gas (TIG) welding, is a high quality welding process that has become a popular choice of welders. It is used when high quality, precision welding is required. In TIG welding a variety of weld types can be performed on several different metals. Steel and aluminum are the two most widely used metals in TIG welding .

An arc is formed between a non consumable tungsten electrode and the metal being welded in TIG welding. A clean weld is formed as a result of the gas shield and this prevents oxidization from occurring. In TIG welding, gas is fed through the torch to shield the electrode and molten weld pool and filler wire is added to the weld pool separately.

In TIG welding reactive metals such as magnesium and aluminum are blended together. This welding method became popular and useful in the early 1940s. As a result, this has greatly propelled the use of aluminum for welding and structural processes. TIG welding is commonly used for both high quality and manual welding.

Gas shielding typically used for TIG welding includes argon, helium, or a combination of both. These two gases when combined ensure a higher welding speed and welding penetration. In TIG welding Argon is preferred by most welders as is heavier than air and provides better coverage when welding.

Different types of joints are used in TIG welding and these include the butt joint, lap joint, corner joint and t-joint. The butt joint can be welded without the assistance of a filler rod. With this type of joint, two pieces of metal are joined together along the seams.

There are several benefits of TIG Welding which include: Superior quality welds Welds can be made with or without filler metal Precise control of welding variables (heat) Free of spatter Low distortion
