MIG/MAG welding is one of the most commonly used of all welding processes. MIG/MAG welding processes are very versatile and can be used in a range of sectors, including the metalworking industry, shipbuilding, steel and container construction, and the automotive industry. MIG/MAG processes can be used with components of different thicknesses and geometries, and which are made from different materials.
MIG- MAG Welding
Direct current is used for MIG/MAG welding. The arc burns between the workpiece and a consumable wire electrode, which is also the source of the necessary filler material and is essentially endless. It is supplied either on a spool or in a drum and is guided to the contact tip by the drive unit. The free wire end is relatively short, which allows a high amperage to be used in spite of the thin wire electrodes.
What is the Difference Between MIG and MAG?
MIG (Metal Inert Gas) welding is a welding process in which an electric arc forms between a consumable wire electrode and the work piece. This process uses inert gases or gas mixtures as the shielding gas. Argon and helium are typically used for the MIG welding of non-ferrous metals such as aluminium.
MAG (Metal Active Gas) welding is an arc welding process where an electric arc is created between a consumable wire electrode and the material to be joined. MAG welding uses active shielding gases, primarily for the welding of steels. These shielding gases are mixtures of carbon dioxide, argon and oxygen.
The only difference between MIG and MAG is the type of shielding gas used.
The make-up of the shielding gas is important as it has a significant effect on the stability of the arc, the metal transfer and the degree of spatter. The shielding gas also impacts the behaviour of the weld pool, with particular regard to the penetration and mechanical properties of the welded joint.
Advantages of MIG/MAG Welding
- High welding speeds can be achieved while still maintaining a high weld seam quality
- Greater deposition rates
- Well-suited to mechanized and automated welding
- Low filler metal costs
- Less post welding cleaning
- Better weld pool visibility
- Ultra low hydrogen process
- No slag formation
- Simple ignition of the arc
- Well-suited to out-of-position welding and welding in difficult positions
Benefits of Robotic Welding
- Finding and training manual welding personnel; it is a long, difficult and expensive process.
- With a robotic welding system, instead of finding and training a large number of welders for
- work, you can optimize your staff count by having an excellent welder that controls the operation of several automatic cells.
- The parts to be produced come out with the same quality and standards every time.
- The need for cleaning after welding decreases.
- Welding wire and consumables are used more economically in robotic welding and less waste, thus reducing the total cost of the product to be welded.
