Welding technology explained in an understandable way: What is the difference between MAG and MIG?

In so-called shielding gas welding, a gas or a gas mixture is directed onto the workpiece via a gas nozzle. This shielding gas prevents undesirable reactions of the material with the ambient air, which can have a detrimental effect on the durability of the weld seam or the entire workpiece. MIG and MAG are now two different welding processes that use shielding gas in different ways.

Metal welding with active gases (MAG for short) usually uses a gas mixture consisting of argon, carbon dioxide and/or oxygen that prevents free oxygen from penetrating the workpiece. In addition, the active gas has a stabilizing effect on the arc, which ensures better results for the weld seam.

In metal welding with inert or inactive gases (MIG for short), pure argon or pure helium are used as shielding gases. Sometimes a mixture of both is also used. In contrast to MAG welding, the inert gas cannot react with the base materials and filler materials and therefore permits very high temperatures during the welding process. This makes it possible to work faster while maintaining very high quality.

The different shielding gases also determine the suitability of the respective welding processes for certain applications. For example, MIG welding can be used in particular to weld precious metals such as titanium and copper, as well as aluminum, aluminum alloys and other non-ferrous metals. MIG welding is primarily used in mechanical engineering, precision engineering and nuclear technology and is very suitable for the manufacture of pipes or containers, among other things. MAG welding, on the other hand, is mainly used to weld together workpieces made of low-alloy or high-alloy steel.

Things worth knowing about MIG welding

Gas-shielded welding has become the standard in many areas of industry. The reasons for this are the high quality of the welding results and the high working speed, which benefits the economy. While the MAG welding process uses an active shielding gas, the MIG process uses a metal-inert gas for arc welding. This does not react with the base materials and filler materials of the workpieces and also permits the use of very high welding temperatures. It is particularly suitable for welding non-ferrous metals such as copper, aluminum or aluminum alloys. As a rule, pure argon or pure helium are used as shielding gases in this process.

Things worth knowing about MAG welding

Similar to MIG welding, this welding technique is also very efficient and is one of the modern welding techniques with inert gas. Arc welding with inert gases also works with an endless wire electrode that is melted down. The welding itself takes place under a shielding gas cover to prevent undesirable oxidation processes in the workpiece or the weld seam. However, the MAG welding process relies on an active gas. These are usually active CO2 or oxygen shielding gases which, together with argon or an argon mixture, shield the molten pool from the negative effects of the ambient air. The MAG process is suitable for arc welding of alloyed and unalloyed steels and for processing CrNI steel. MAG welding technology is used almost everywhere in the metalworking industry as well as in steel construction, shipbuilding, vehicle construction and tank construction.

Questions and answers about MIG-MAG welding technology

  • What is the main difference between MIG and MAG?

    In arc welding with MIG-MAG, a shielding gas is always used. The difference lies in the type of shielding gas. With MIG (Metal Inert Gas), the shielding gas does not actively react with the molten pool. With metal active gas or MAG, this is different.

  • What can be welded using MAG?

    The MAG welding process can be used to weld very thin-walled plates. It is also the ideal process for welding steel of any grade, especially stainless steel and structural steel.

  • Which gases are used for MIG-MAG welding?

    In the MIG process, the shielding gas used in the welding process consists of inert or inactive gases such as argon or helium. The MAG process, on the other hand, uses active gases such as carbon and oxygen in combination with an argon/carbon mixture.

  • When should you weld using the MAG method?

    If you want to weld low-alloy, unalloyed or high-alloy materials, the MAG process is the ideal choice.

  • When should you weld using the MIG process?

    Welding with inert gases has the advantage that they cannot react with the base and filler materials. Therefore, the MIG process is suitable for welding copper, aluminum, aluminum alloys and various other non-ferrous metals. In addition, welding can be performed at higher temperatures.
