What is tig welding and When to TIG Weld
Before I explain to you what is Tig welding let’s give you a ride back in time. Earlier when the short pulsed electric arc by Humphry Davy in the 1800 followed by the discovery of continuous electric arc by Vasily Petrov and not too later than that the arc welding slowly and steadily was brought to the light by C.L Coffin who was successful in brainstorming the concept of the use of welding in an inert gas atmosphere in 1890.
When it came to weld with nonferrous materials such as magnesium as well as aluminum always turned out to be a nightmare as these metals always were reactive to air. The situation was handled with the use of bottled inert gases in the early 1930’s and a few years later than that a direct current enabled gas shielded welding technique came into existence as it was used to weld magnesium.
Ok so what is Tig weld the word TIG stands for Tungsten Inert Gas, commonly known as TIG welding and this word has originated from United States Of America (USA).
Tungsten which is also referred as wolfram basically a metal which has an extremely high melting point of 3300oC which depicts that the tungsten has twice as more than the fusion point than the regular materials which are welded. Inert Gas and Inactive gases are just one and the same which is a gas that never tries to combine with other materials.
In Germany, the (TIG) Tungsten Inert Gas welding is better known as WIG which stands for wolfram inert gas welding. There lie many ways and types of welding and you have to know what is tig welding, among the TIG or also called WIG carries the International standardized position of welding methods. And also it is mandatory to adopt the filler material which is added either manually as a bare wire.
In the welding course the electrode the welded process which is protected very well against the detrimental effects of atmospheric air by inert gas shielding. Gas Tungsten Arc welding better known as HeliArc and tungsten inert gas (TIG). The TIG process came up in 1930’s when the urge to weld the magnesium became superficial. The new name to these are gas tungsten arc welding (GTAW) and the new name turned up very popular in the technical book of welding related subjects.
First, we started by knowing about what is tig welding but a process that is involved in order to weld something especially metals. So now it is essential to know how the welders actually work on it. The actual process is started as per the methods are given below.
Choosing the electron:
First, the welder will learn something regarding the electrode so that they can very easily choose the best one. In fact, there are many different varieties of electrodes available in Aluminium is one of the best electrodes to sustainability maintains progressive results.

Inserting the electrode:
After that, the electrode will be inserted into its collection. This process needs to be taken properly as it requires proper care and attention apart from that the screwing as well as unscrewing need to be done carefully.
what is tig welding Settings:
Now it’s time for the welder to choose the settings of the TIG welding machine. Depending upon the type of the welding process it is essential that the vendor should consider the accurate settings to make the process more efficient. All the settings are however professionally known to the welders so they will instantly keep accurate precision over it.
Turn on gas:
It is essential that the vendors should know about the best gas for tig welding as this will help in enabling the process very easy. In most of the cases, Argon gas is used this is especially true in the case of aluminum electrodes. Underscore in order to keep the building from becoming more corrosive.
Preparing metal with welding table:
Of course, this is one essential step where the large metal area is required in order to extract the electric flow through the metals. The process is carefully executed by the vendors. You have to be careful while growing about the best tig welder for a beginner especially if you are not well experienced in order to handle it for the very first time.
It needs to be checked thoroughly with the final process is implemented to check up on to know its accuracy. After that, it is given final touch and also start weld pool by jamming down the pedal fast to form a weld pool and finally, the process will be completed.
It is even essential to know about the cheap tig welder as this will help in specifying the best time to tig weld. This will have ever between completely based upon the application and in case if there are any joints that need to be formed. However, it is the responsibility of the welder to take care of it. Apart from that, you can also find some exclusive and the best tig welder under 1000 which are truly helpful for you.
Tig welding principle
The tig welding works on the assumption as the arc welding works upon in this process a high-intensity arc is created in the midst of electrode and workpiece. Normally in the tig welding, the workpiece is connected to positive whereas the electrode is connected to the negative terminal.
Heat energy is produced by the arc which is then used by the fusion welding to join the metal piece by fusion welding. In this process, the shielding gas is utilized for the protection of the weld surface from oxidization. In this welding, metals are fused together
Types of equipment used in Tig welding
- Argon gas bottle
- The cover gas starter kit
- Safety starter kit
- Torch Stand
- Torch and Electrode Kit
- Torch Cable
- Ground Cable
The power source used by Tig:
The most important part of any tig welder is the power source, basically, it is the component through which the tig welder houses it’s potential energy to work. The electric current of high power is required for the tig welder to work. AC and DC tig welder can work on both irrespective of the availability or absence of either one of them.
Depending upon the type of material on which the work is going on let’s say stainless steel, mild steel, copper, titanium, nickel alloy in these cases DC current is used and on the other hand for metals like aluminum, an aluminum alloy including magnesium. The whole welder consists of a transformer a rectifier and a whole lot of control buttons
Advantages and limitations:
Just like any electronic equipment having its own advantages and disadvantage or can be termed as merits and demerits
