When MIG welding STEEL a mixture of Argon -- CO2 is used. 75% - 25%
ER70S-6 is a very common filler metal when welding with Gas Metal Arc Welding or Gas Tungsten Arc Welding on a low carbon steel (mild steel). This can be purchased as a spool or in rod form.

ElectrodeTIG welding uses a tungsten electrode that is not consumed during the welding process. MIG welding uses a metal electrode that doubles as filler material for the weld and is consumed during welding.Shielding GasTIG welding primarily uses argon as a shielding gas, with helium occasionally used. Argon is also the primary shielding gas used in MIG welding, but argon mixtures and carbon dioxide are often used for different applications.Filler MaterialTIG welding requires a separate filler material in rod or wire format because the electrode is not consumed. MIG welding delivers the filler material via the electrode.Work Piece MaterialsTIG welding can be applied to just about any metal, from steel to aluminum and exotic alloys. MIG welding was developed for nonferrous metals, but can be applied to steel.DifficultyTIG welding is considered to be more difficult than MIG welding because tighter tolerances have to be maintained between the electrode, the filler rod and the work piece.
Welding process that uses both flux core, within the wire, and gas to protect the molten weld pool from contamination.
Carbon dioxide, Argon, Helium, but not Nitrogen, can be used as 'shielding' gas in Gas Metal Arc Welding.
These inert gases are used in gas tungsten arc welding, and also in gas metal arc welding for the welding of non-ferrous metals. Semi-inert shielding gases, or activeshield gases, include carbon dioxide, oxygen, nitrogen, and hydrogen. These active gases are used with GMAW on ferrous metals.
Welding cylinders contains different types of gas. Oxygen is common to all the kinds of cwelding. The other common gas used is a combustible gas like acetylene which is the fuel for the torch. The fuel gas could also be hydrogen, MPS or MAPP gas, butane, propane, or propylene. Some welding (e.g. aluminum welding) requires a shield gas which protects the surfaces near the flame and improves the quality of the weld. These can include helium, argon, carbon dioxide or nitrogen.
oxygen and acetylene gas Argon gas is used in MIG and TIG welding
What type of welding can we use LPG ?
the nitrogen gas is used for nitrogen fixation
Some methods are used: - electron beam welding - laser beam welding - gas wolfram arc welding - gas metal arc welding - resistence welding - brazing
farting gas:)
why oxyacetylene filler rods cannot be used for gas tungusten ar welding
TIG welding uses Argon.
Oxygen is used for cutting torches and medical uses. Nitrogen is used as an inert gas for chemical reactors and also in the production of Ammonia. Carbon Dioxide is used in fire extinguishers and also for film effects. Helium is used for filling balloons and a carrier gas for chromatography. Argon is used in welding.
Your local welding supply store should have nitrogen tanks, or know who your local compressed gas supplier is. You will most likely need to pay a significant tank deposit, and purchase a gas regulator for the tank.
