MIG/MAG WELDING: THE HIGH-SPEED WELDING PROCESS
  • MIG/MAG welding is also referred to as gas metal arc welding. A differentiation is made between metal inert gas welding (MIG) and metal active gas welding (MAG). MIG/MAG is currently the most frequently used welding process and allows for particularly high welding speeds. It can be used in a manual, mechanized or robot-supported manner.
MIG/MAG WELDING: THIS IS HOW IT WORKS

Steel is primarily composed of iron and a maximum of 2.06% carbon. Alloys with a higher proportion of carbon are known as cast iron. If the proportion of sulfur and phosphorus accompanying iron is less than 0.025%, it is called stainless steel.

Not every steel can also be welded: only pure steels, i.e. alloys with a carbon content of less than 0.22%, are suitable for this process. As a rule, the more impure the alloy, the harder it is to weld the steel.

WHICH GASES ARE USED IN MIG/MAG WELDING?

MAG welding uses active gases such as pure CO2 or mixed gases (argon, CO2, O2) in various compositions. These are highly reactive. The MAG process is used for unalloyed, low-alloy and high-alloy materials.

MIG welding, on the other hand, uses inert, i.e. unreactive, gases such as pure argon and helium or mixtures of argon and helium. The process is suitable for welding materials such as aluminum, copper, magnesium and titanium.

    ADVANTAGES AND DISADVANTAGES
    • Easy to learn
    • High welding speed
    • High deposition rate
    • Low filler metal costs
    • Well suited for mechanized or robot-supported welding applications
    • Easy ignition of the arc
    • In outdoor areas or in draftyhalls there may be problems with maintaining the shielding gas
    • Sensitive to rust and moisture
    WHICH MATERIALS ARE SUITABLE FOR MIG/MAG WELDING?

    The material that is most frequently used in the gas metal arc welding is steel. In addition, aluminum and stainless steel alloys can also be welded well with MIG/MAG.
