TIG Welders promise to give Quality Weld    by mspaul

Tungsten inert gas (TIG) welding is one of the remarkable discoveries of metal welding science that not only promises to provide a strong weld but also gives an easy solution to join complex materials. The tig welders use non-consumable tungsten electrode and inert gas, usually argon. This method takes place by means of metal vapors along with ionized gas known as plasma. The energy generated from current power supply helps to produce plasma.

Several types of metals like magnesium, stainless steel, copper alloys and aluminum are easily welded by TIG technique. Actually, it is often applied to weld non-ferrous metals. This technique enables experience welders to have a good control over the weld. This character also makes it better than MIG welders and stick welders.

People are required good amount of skill and care to carry out TIG welding procedure. Here, you have to hold welding torch to feed metal filler and strike an arc. High frequency generator is needed to produce arc formation by creating a path through shield gas. The ideal distance between welding area and electrode is 1.5-3 mm to strike good arc. Tungsten is widely used in metallurgical industries because of its high melting point approximately 3422 Degree Celsius. This pool is created by circling the welding torch around the welding area. Due to high melting point, tungsten naturally becomes an ideal choice for the arc welders and electrical works where temperatures increase thousands degree celsius.

Welding process is a kind of controlled heating for sculpting several forms of machines. Nowadays, different types of TIG welding techniques are used for different industrial allocations such as dabber, hot wire, and the pulse current. They are required in shaping decorative materials by which essential precision can be found. TIG welders do not emit huge smokes, spatters and harmful gases like MIG welders and it can be operated by AC or DC power supply
