In recent years, gas has become the most popular welding process to be used in small metal industry and also in the construction industry. Gas welding is one of the most popular welding processes which used for joining metals, both for big and small welded work. Gas comes into use because of its availability and safety. It also has a very easy to use.
Gas welding can be used any types of metals like steel, cast iron, aluminum etc., also it is widely used for welding thin and thick metals. Also, gas can weld metals which are at high temperature and low temperature. Gas welding is considered to be as the most economic process of welding.
There are some limitations of gas welding such as it consumes more money in the process of operation and also it is not suitable for joining materials which have very high speed.
Gas welding has also been used for joining materials with high speed such as aluminum, steel etc. Gas welding has a risk of fire during the process of welding. It is also not suitable for joining materials which have high temperature such as steel, cast iron and aluminum etc.
Nowadays, with the use of gas welding has become very popular in the construction industry and it is used for joining metals at high speed. Gas welding is also known as MIG welding which stands for metal inert gas welding.
MIG Welding
MIG welding is an abbreviation of metal inert gas. It has been used since the early 1900s. The welds which are made by MIG welding are made in the presence of gas which has a lower hydrogen to oxygen ratio. MIG welding is also called metal inert gas welding, because it uses no shielding gas and it is also known as smooth metal inert gas welding.
What type of gases are used in MIG?
There are several types of gases used in MIG welding
M1: Argon (Ar) is the gas used in the M1 welding process. It is a colorless gas with an odorless odor. Argon is also known as atomic number 18 gas. The variation of pH level of the water which contains Ar is 3.2. It can be easily produced and it has a very low cost price.
M2: Helium (He) is also called noble gas, it has a very low cost and it is also used as a shielding gas. Helium is a colorless gas, having an odorless odor. It is lighter than air, has a boiling point of -268C and at normal temperature it will not mix with air.
M3: Argon Mixture (Ar/He) is also known as metal inert gas mixture or inert gas mixture. This mixture contains both Ar and He gases in equal proportion and it contains the same percentage of oxygen which is present in the air.
M4: Oxygen is also called the element oxygen, it is a colorless gas with a very strong odor. It has a boiling point of -183C. Oxygen is also used as a shielding gas in MIG welding.
M5: Carbon Dioxie is also called CO2, it has a very strong odor. The variation of pH level of the water which contains Carbon Dioxie is 2.8. It is also used as a shielding gas in MIG welding.
