MIG/MAG welding, which is a universal method that allows to obtain the alloy at a very high speed and in all positions.
MIG/MAG welding consists in welding by means of an electric arc produced between the hot melt electrode and the material welded. A hot melt electrode is a wire fed continuously. In the MIG/MAG welding process, an electric arc glows between the metal electrode in the form of a continuous wire and the material welded. The arc and the welding pool pond are protected by an inert or active gas stream.
The MIG/MAG method is suitable for welding the majority of materials; hence solid and core wires suitable for various metal species are offered.
The following terms for the process of welding with a hot melt electrode in a gas shield are used:
- MIG - (Metal Inert Gas) - this name refers to the welding process when a chemically inert gas, e.g. argon, helium, is used as a shielding gas.
- MAG - (Metal Active Gas) - this name refers to the welding process when a chemically active gas, e.g. CO2, is used as a shielding gas.
- GMAW- (Gas Metal Arc Welding) is an abbreviation used mainly in the USA and is common for both methods: MIG and MAG and indicates the use of a solid wire.
- FCAW- (Flux Cored Arc Welding) - an abbreviation for a welding method similar to MIG/MAG (GMAW), however, instead of a solid wire, a core (powder) wire is used. If the wire is filled with powder generating protective gases during welding (Innershield method), supplying of the shielding gas from the outside (from the cylinder) is not required.
welding with an electric welding machine, welding with a semi-automatic machine, semi-automatic welding - are the common names of the welding process, both with the MIG and MAG methods.
Application of the MIG/MAG method
The MAG method is mainly used for joining non-alloy, low-alloy and high-alloy structural steel, whereas the MIG method is used for welding aluminium, magnesium, copper and other non-ferrous metals and their alloys.
Semi-automatic MIG/MAG welding is used in almost all branches of the welding industry. Below we propose MIG/MAG welding equipment, which are commonly used in:
- heavy industry and machinery industry: shipyards;
- production of steel structures, pipelines and pressure vessels,
- repair and maintenance industries,
- thin sheet metal processing, especially in the automotive industry, production of superstructures and in small-scale industry
