If you are known with the welding procedure, then you must have heard that the welding process is dependent on the product which you need to weld. The right application on the welding material would allow you to get the best results and that’s why it is important to focus on choosing the right welding strategy.
Do you know that gas is also used in welding processes? Yes! It is true the gas metal arc welding is done by using wire welding electrode and then it is joined with arc through which electric current is passed after which the shielding gas is used to heat the particular wire till its melting point.

There are different types of gases used in welding but mainly argon is used by the professionals. Here, you will know all about the usage of argon and reasons behind it along with the benefits.
What is argon gas welding?
When welding task is done in the presence of argon gas, then it is known as argon gas welding. The semi-inert and inert gases are used in the welding and it helps in protecting the welding area from the other atmospheric gases.
It helps in improving the weld quality due to which one should choose the best quality of welding gas. If you will not choose the right inert gas during welding task, then it can result in excessive splatter and less productivity.
The shieling metal welding arc uses the electrode which is covered into flux and it produces CO2 after heating. At this time, the inert gas would provide shield to the welding metal and it forms a kind of plasma cloud around it.
Almost every noble gas have low chemical reactivity and they are colorless and odorless also. Neon, Helium, Argon, Xenon, Radon, and Krypton are the inert gases.
The argon gas is heavier and it would need a lesser flow rate as compared to the other gases. It won’t react with the molten metals and it can ionize easily. It has low thermal conductivity and it can’t be used for welding steel if 100% pure.
Pure argon is only used with non-ferrous and aluminum metal welding. If the helium is added to it, then the heat is transferred faster. The argon tank can last for three to six months if you will get the 40 scf tank.

It is really important that you get the nice quality of argon tank which is available in the market so that you don’t have to regret purchasing it. The argon cylinder isn’t available with the regulator but it is advised that one should buy the regulator with the cylinder.
The best kind of regulator would allow you to get the welding task done in an easier manner and you will never regret buying the regulator for the argon tank at all.
Is argon gas hazardous for humans?
Argon gas has numerous safety concerns about which one should be aware of before usage. It is a safe gas because of its non-inflammable and non-toxic nature. It is not poisonous at all and won’t burn.
It is available in the compressed tank but safety is taken care of while working with the tanks or argon. It is almost 38% denser as compared to the normal air if one works in the confined and closed spaces.
It would be better if you have good ventilation and it is used in a limited amount due to which there are no chances of any harm created by it. This is where it is advisable to use a high quality auto darkening welding helmet for the best protection possible.
Why using argon gas is good for welding?
Most of the times, shielding gases and particular argon gas are used in TIG and MIG welding tasks. Here MIG refers to Metal Arc Welding while TIG refers to Tungsten Arc Welding. It helps in protecting the weld area from water vapor and oxygen.
The water and oxygen in the air can make it difficult for the person to perform welding and it also deteriorates the quality of it.
The argon gas is dense as compared to the air and that’s why it can get wrapped around the weld due to which it would need fewer flow rates in order to distribute the gas. Only noble and semi-noble gases are used in this purpose and you can choose argon and helium both.
Most of the times, people use totally pure form while sometimes, they also the blended and mixed form to weld the metals. Here are the reasons due to which argon is used in welding process most of the times:
- It becomes easier to perform welding when one is using argon gas because it prevents oxidation of the metal.
- There won’t be much loss of the alloy elements when the metal is transferred towards the arc if argon gas is used.
- Spatter and burn like side-effects can be reduced by the usage of argon gas.
- It is easy to adjust the individual gases as per the requirement of the welding material.
- It would protect the welding arc for a longer time.
So, these are the major reasons due to which argon gas is used most of the time among the other gases available in the atmosphere. The argon comes in a compressed tank which is filled with argon gas but it is totally safe and won’t harm you at all. The only a small amount of gas is used during the welding task to avoid any splatter during the work.

The shielding gas which is used in the welding procedure is the major part of successful welding. So, using argon can be really beneficial for achieving proper penetration, good welding results, and uniform beading.
The appropriate shielding gas needs to be sued while performing TIG and MIG welding tasks. If you will use the wrong shielding gas, then it would result in bad bead shapes, overheating, excess splatter and poor penetration.
If you want to get the welding task done in a proper manner, then you should make sure that you get the right quality of gas.
