Argon is a chemical element in the periodic table that has the symbol Ar and atomic number 18. 3rd noble gas, in period 8, argon make up 1 % of the Earth's atmosphere.
The name " argon " is derived from the Greek word meaning αργον " lazy " or " inactive " , a reference to the fact that hardly element undergoes a chemical reaction . Complete octet (eight electrons) in the outer atomic shell makes argon stable and resistant to bonding with other elements. The triple point temperature of 83.8058 K is a fixed point in the International Temperature Scale decisive 1990.
Welding with argon welding technique is relatively new in the world of welding. This technique is classified as in TIG (Tungsten Inert Gas) is the process of blending together reactive metals such as magnesium and aluminum. To operate it needs heat stable. Boiling point of more than 3,000 degrees Celsius. It is made of iron molecules can come together and more flat welding results.
Type commonly used shielding gas for TIG welding is argon, helium, or a combination of both. When combined, the two gases can guarantee a higher welding speed and penetration welding. Argon is the most widely used in TIG welding because argon is heavier than air and provide better coverage during welding .
Argon welding technique is often considered the most difficult of all the welding processes commonly used in the industry. Because the welder must maintain a short arc length / feed and skills necessary to prevent contact between the electrode and the work piece.
The difference with other welding techniques.
Source of the fire, using fire originating from sources of electricity generated by a welding machine transformer (inverter). At the source of the fire carbide welding is a gas produced by immersion carbide, while the welding acetylene, acetylene gas used as fuel to make a fire source.
Beam welding, the welder / welding operator on the obligatory use argon welding mask / safety mask at the time of welding, is due to light reflected by an electrical fire source is very bright, so use a mask that fitted black glass designed to reduce glare on the eyes, so that liquid metal can be seen clearly in order to be directed. Without using welding mask welding impossible to get a good result according to the standard, that is your eyes will be swollen and watery, and sting.

The reason for using.
Net acetylene than welding, welding carbide or electrodes, because argon gas that is used to support the welding process almost is not any pollution, only a little smoke. While the material was welded welds clean, because it does not cause the type of welding metal splash or crust.
Neat and meticulous , results may be neat and welding very conscientious , could reach the narrow position without compromising the look / performance , welds can remain small and straight , and can be used for materials with a thickness of 50mm or more up to 1mm thinner even longer .
For welding stainless steel (SS), this will probably be the main reason, because acetylene and carbide welding cannot be used for welding, while welding electrodes / sticks can still be used only for material with 2mm thick or more, that would still leave the spark that sometimes difficult to clean so it is not recommended for welding on existing material in direct contact with pharmaceutical products, food & beverage and cosmetics.
