MIG/MAG welding is the most employed and flexible welding method within the iron and metal industry. MIG/MAG welding (also called CO2 welding) is a welding method, in which the welding material, the rod, is added during the welding process. By utilising different types of welding material, protection gasses, and amperages/frequency in the welder, it is possible to weld all materials suited for welding with MIG/MAG welding.

KK Metal has wide experience with MIG/MAG welding in steel, stainless steel, and aluminium, both manually, with machine, and welding robot.

MIG/MAG – welding in many types of material

The term MIG/MAG welding reflects that two different methods can be applied with the same welder:

MIG (inert gas) is commonly used when welding stainless steel, aluminium, and other metals. In this process the gas is inert, i.e. it is not included in the actual process of welding, but solely has the purpose of preventing the presence of oxygen.

MAG (active gas) typically covers welding steel materials with CO2 (carbon dioxide). Partly, the gas protects the welding bath, and partly, contributes to the melting process.

A modern MIG/MAG welder is computerised, and it self-regulates in a number of ways, e.g. amperage, DC welding (direct current) or AC welding (alternating current), and in frequency (Hz). Thereby, with the chosen welding rod, type of gas and power, a modern MIG/MAG welder provides the opportunity of welding in all types of steel, stainless steel and other metals.

The built-in computer in a modern MIG/MAG welder further provides the option of controlling the welder with a robot.
