There are many types of gas welding stainless steel wire, gas welding of different metals. Depending on the intended use, material, welding, or funds that people will choose gas for welding and cutting metal. for example, customers will choose tig welding and gas welding of stainless steel will be normal argon, and select the gas to welding metal iron, steel, the majority of selected CO2.
The importance of choosing the right gas welding, metal cutting type:
conventional welding machine mainly used CO2 or Argon, but depending on each type of welding material that people will choose gas protection separately. Each type of gas protection welding wire, welding, metal cutting will work efficiency and quality of welds different.
Gas protected welding metal effect, to protect the weld limit the oxidation penetrate the weld. From that augment the aesthetics of the weld should be, so the selection of protective gas is very important.
If you choose the wrong gas welding cutting metal or gas welding stainless steel, you can make welds will not be enough matured look, basketball isn’t beautiful.
There are gases to welding metal cutting, how?
Gas welding, metal cutting, aluminum machines Mig?
For gas welding and cutting metal is aluminum, the majority of gas Argon (Ar) or gas mixing.
- Argon gas is colorless, odorless and heavier weight of air is about 25%. The boiling temperature of the gas is Ar -185 degrees C under the pressure often. Argon is used is mainly because it can be used for the detailed aluminum thickness up to 25mm. Results welds with gas protection Ar has matured high.
- Mixed gas for welding, cutting metal, including 35% Argon + 65% Helium: Mixed gas protective welding this metal can be welded well with the thickness of aluminum bar from 25 – 76mm. In particular, it helps increase the flow of dilute metal vung flow when welding the alloy of Al + Mg.
- Mixed gas to weld metal cutting 25% Argon + 75% Helium: With this ratio, it can weld all good with the details of a thickness on the 76mm. Mixed gas protection, this will help welds have high grip, good fusion, minimize risk and air bubbles.
Mig welding gas welding stainless steel is air, what?
Gas welding stainless steel without welding machine can be used is CO2, gas welding stainless steel is the Argon gas or mixed reality (Ar and O2). Let’s see if they have different effects when welding stainless steel like?
- When Mig welding use, air tank, CO2 welding steel, then welds tend to devour down, using Argon, then the weld will be slightly convex out.
- Mixed gas welding stainless steel Ar + oxygen (1%): gas Mixture is well protected both when soldering the detailed thickness, the effect of limiting fire border.
- Mixed gas for welding stainless steel Ar + oxygen (2%): increased protection good weld ball light more beautiful.
Mig welding Machine gas to weld metal cutting Titanium how?
If it is titanium, it kind of protective gas is Argon, high purity help weld clean and without impurities gas, no bubbling.
Gas protection welding low alloy steel machine Mig?
Low alloy steel has high ductility and toughness should use the gas mixture in order to increase efficiency.
Mixed shielding gas Ar + oxygen (2%): weld durability and reduce fire border. When Mig welding with low alloy steel, you don’t necessarily have to heat first.
Gas to weld metal cutting Carbon steel?
Welding of Carbon steel using Mig welding using gas mixture Argon + O2 or Argon + Co2.
- Mixed gas protective welding metal Ar + oxygen (1 – 5%): protect the flow of dilute immediately after the primer arc to make the weld shiny, non-flammable border. Compared to the Argon gas purity, then the gas mixture allows welding time faster.
- Mixed shielding gas Ar + Co2 (3 – 10%): the Type to welding metal protect this region flow dilution better. Limit of the gas mixture, this is only applicable if the flat welding and welding in the horizontal angle.
Mig welding gas welding and cutting metals, copper, Nickel, how?
When welding metals copper, Nickel, use the Argon gas purity or mixture Argon + Nitrogen + Helium are.
- Argon purity: Type of gas this protection helps welds have the adhesion stronger. Help protect welds from the ingress of air, the flow thinning of good weld on 3mm.
- The mixture Ar + Heli (50 – 75%): increased energy soldering the detailed thickness by distribution the heat better.
Why are now using Co2 gas for welding is mainly?
Although using Argon gas and mixed gas Ar will result in weld metal cutting more beautiful. But actually popular use gas welding of stainless steel and gas to weld metal cutting is more CO2. Because the price of gas cylinders welding stainless steel CO2 is much cheaper than the average gas Ar and the gas mixture Ar.
If skilled craftsmen know how to combine technical Mig welding still ensures the quality of welds and fully matured, at least when to back.
Gas Argon is a noble gas with high prices should only priority welded aluminum, copper, Nickel, Titanium… when manufacturing all kinds of machinery, shipbuilding, use mechanical manufacturing, heavy industry,…

There are also Nitrogen (N):is also protective gas in the form of mixtures and used to weld copper.
So there are 4 types of gas welding and cutting metal including Argon (Ar), Helium (He), CO2, Nitrogen (N) and the gas mixture of them. Each gas has a different effect with each welding material and the weld metal. If you need further advice on gas for welding, cutting metal is air, what price how much it please contact MIGCO to be supported.
