Meet the quality and aesthetic standards with TIG welders

TIG welding

TIG welding also referred to as Gas Tungsten Arc Welding (GTAW), is a manual welding process. This welding technique takes considerable amount of practice to learn and requires the use of both hands. It has become a popular choice when it comes to meet the quality and aesthetic standards. TIG is a specialized form of welding and can be used on both thinner as well as on exotic metals. The most common types of TIG weld include T-joint, lap joint, butt joint and fillet joint. Almost all types of metals can be welded using TIG welders. The metals included are: carbon, stainless steels, low alloy steels, nickel, aluminum, magnesium, titanium, copper and its alloys and many more.

Main advantages of TIG welding:

· It can produce high quality and neat welds

· The welds produced are more corrosion resistant and ductile

· While welding, you get the excellent visibility of the weld puddle

· No smoke or spatter produced

· It proves very effective on thin materials and components of thick materials

· The welding professional has a higher degree of control over the heat input

·  It works on a variety of metals; virtually on all metals

·  This welding process can be easily automated

·  It can weld without filler material i.e., autogenous weld

·  It works on both AC and DC as power supply

·  Current and travel rate can be changed during the process which proves very useful for complex welds

Things required while performing TIG welding are mentioned below:

Before welding, you must know about the materials and consumables used during this welding process.

Shielding Gases

Shielding gases are used to protect the weld bead and the metals against any atmospheric contamination. The most commonly used gas is argon. Also, the combination of different gases can be used based on the heat required, alloy and the thickness. For example: Pure argon is used for welding aluminum and a mixture of argon and carbon for welding steel.

Electrodes

Earlier, only tungsten-thoria electrodes were used for TIG welding but it had some health hazards. Therefore, now mostly cerium and lanthanum based tungsten electrodes are used.

Filler wire

When you need to weld thinner metals like stainless steel, no filler wire is required. But it becomes necessary to use a filler wire when you have to weld certain alloys and heavy sheet metals.

Power used

Direct Current (DC) is the most commonly used power source in TIG welders. But for some exceptions such as for welding aluminum, alternate current is used (AC).  

What makes TIG welding so different from another popular welding technique, MIG?

·  TIG stands for tungsten inert gas welding technique whereas MIG stands for metal inert gas welding.

·  In TIG, tungsten rod is used as electrode and in MIG welding, metal rod is used as electrode and the work piece is used as the another electrode.

·  TIG is gas shielded tungsten arc welding and MIG is gas shielded metal arc welding.

·  In TIG, welding rods are used that are slow feeding whereas in MIG, the continuous feed electrode wire is used that are fast feeding.

·  TIG uses non consumable tungsten electrode and in MIG, a consumable metallic electrode is utilized.

·  In TIG, for protecting the welded area from the environmental contaminants a gas is used and in MIG, the welded area is flooded with a gas that doesn’t combine with the metal.

·  TIG can work with both AC and DC while MIG works on DC with reverse polarity.

·  TIG can work with or without the filler metal and on the other hand a filler metal is compulsorily used in MIG welding process.

·  TIG is a slow process but can produce more accurate welds whereas MIG is a faster technique.

·  TIG can weld metals up to a thickness of 5 mm and MIG can weld metals up to a thickness of 40 mm.

·  TIG can weld metals of almost all kinds such as steel, aluminum and other exotic alloys and on the other hand MIG process is used to weld non-ferrous metals and sometimes also steel.
