Tig Welding

TIG welding is Tungsten inert gas welding. This is a welding process that makes uses of the tungsten electrode that is non consumable. This electrode is used to form the weld. The welding area will be shielded with the help of an inert gas which is most commonly argon. This is done to protect the weld area from contamination in order to help for a better weld. Sometimes a filler material is used. There is a constant flow of current from a high voltage power supply. This is conducted through the arc through a column of highly ionized gas. Also aiding to the weld is a column of metal vapors through which the high conducting current would pass and is known as plasma. This welding process is mostly used to weld thin sections of steel or non ferrous material. The weld that is formed is exceptionally strong. Also the process is extremely precise as this process will grant the welder greater control over the welding process. This process is however slower and difficult to master than other welding processes. It would take a welding expert to complete this process successfully and it is not meant for beginners. It is the most difficult welding processes among all the other methods of welding.

The arc length that is to be maintained in this welding is relatively short. Therefore the welder must be careful so that the electrode and the metal that is being welded do not touch each other. A great skill and care is therefore required for such a process. Also this process engages both the hands. This is because in both cases the filler material must be fed into the weld area manually in to the weld area except in certain cases where the weld does not require a filler material. This is most common when welding butt joints where thin metals are combined to form a fusion weld.

The welding arc is struck by a high frequency Diesel generator which will provide an electric spark. The spark will be passed through a shielding gas. This form of welding provides greater welding control than the other welding processes. Therefore the welding that is done through this process is more accurate and precise than other forms of welding. The selection of the shielding gas will have various factors involved. The most influential factor in this regard would be the types of metals that are being welded. The reason why shielding gas is used is because atmospheric gasses like nitrogen and oxygen can contaminate the welding area and cause fusion defects that can lead to weld metal embrittlement. Also the gas will help to transfer the heat from the electrode to the metal. This will help to start the weld and maintain a stable arc.

TIG welding can have several such applications. On our website you can find several of the TIG welding equipment. You can check our site out for the same and buy your TIG welding needs from us. You can click here to get started.

Gas Tungsten Arc Welding (GTAW) is frequently referred to as TIG welding. TIG welding is a commonly used high quality welding process. TIG welding has become a popular choice of welding processes when high quality, precision welding is required.

In TIG welding an arc is formed between a nonconsumable tungsten electrode and the metal being welded. Gas is fed through the torch to shield the electrode and molten weld pool. If filler wire is used, it is added to the weld pool separately.
