There are mainly five types of welding used to join metal to metal. Welding machines are nowadays can perform three or four types of welding and they are available as 3-in-1 or 4-in-1 welding machines. Here we have listed all the welding types and welding machines that are used to combine metal.
Types of Welding
Manual Metal Arc (MMA)
Metal Inert Gas (MIG)
Metal Arc Without Gas (MAWG)
Tungsten Inert Gas (TIG)
Gas Torch Welding (GT)Welding Machines
4-in-1 Arc Welding Machine
Shielding Gas Cylinder
Gas Torch Welding TanksManual Metal Arc (MMA)
MMA is also known as shielded metal arc welding. In this type of welding, a flux coated electrode stick is used as a filler to the welding joints. The electric current from the welding machine is used to generate a spark between the "Joining Metals" and the electrode. This spark melts down the metal and the electrode in order to combine them. MMA welding is used for Iron, Steel, and other metals that have high melting points.
Metal Inert Gas (MIG)
MIG is also known as metal active gas (MAG) or gas metal arc welding. In this type of welding, a wire electrode (not flux coated) is used as a filler to the welding. This welding requires a CO2 or argon gas cylinder to protect the filler against environmental impurities. The MIG welding machine has a wire feed unit and a welding gun. The wire electrode is supplied to the gun by a wire feed unit and shielding gas by a gas cylinder. The electric current is supplied by the machine to generate a spark between the wire electrode and the "Joining Metals". This spark melts down the workpieces and combines them. MIG welding is used to join steel, iron, and other metals.
Metal Arc Without Gas (MAWG)
MAWG welding is done by the MIG welding machine. In this type of welding, a flux coated wire electrode is supplied to the welding gun, and shielding gas is not required (as the wire electrode is flux coated). The electric current is supplied by the MIG welding machine. This electric current generates a spark and melts the workpieces in order to join them. MAWG welding is used to combine iron, steel, and other metals that melt at high temperatures.
Tungsten Inert Gas (TIG)
TIG welding is also known as gas tungsten arc welding. This welding is used to weld aluminum and other metals that melt at low temperatures. In this type of welding, shielding gas is used to protect the weld and tungsten wire is used as a filler to the welding joints. The welding gun used in TIG welding is different from MIG welding. It doesn't require a wire feed unit as the wire is fed to the weld manually.
Gas Torch Welding (GT)
Gas torch welding is also known as oxyacetylene welding. In this welding, oxygen, and acetylene gases are supplied to the welding torch to melt the workpieces and a filler wire is used to fill the welding joints. The filler wire depends upon the metals to be welded.
4-in-1 Arc Welding Machine
This type of machine can perform MMA, MIG, MAWG, and TIG welding.
Shielding Gas Cylinder
It is required for MIG and TIG welding. CO2 and argon gases are generally used for MIG and TIG welding.
Gas Torch Welding Tanks
These are oxygen and acetylene gas tanks that are used in gas torch welding.
