The Fundamentals and Applications of MIG Welding by Amon Engineering
08 August 2022
When combining two or more metals, industries can take advantage of welding.
Welding refers to the process of joining materials by heating their parts together. These heated parts of materials are then cooled so they can be fused effectively. This process does not work similarly to brazing and soldering since the latter options do not melt the materials. What is great about welding is it provides a permanent connection between materials. It can also provide cost savings as it can fully utilise the materials used throughout the process.
Many types of welding can be maximised by industries. But one welding type that may be useful for a lot of them is Metal Inert Gas (MIG) welding.
A Quick Background of MIG Welding
MIG welding, also known as gas metal arc welding, utilises a continuous solid wire electrode in joining base materials together. The said electrode is being fed into a welding gun and to the weld pool, while a shielding gas is then released through a nozzle encircling the cable to prevent the weld pool from being contaminated. As the wire electrode interacts with the workpiece, an electric arc forms, which helps in heating the metal and fusing metal parts.
MIG Welding Benefits and Drawbacks
Tons of benefits and drawbacks are associated with MIG welding.
Starting from its benefit, MIG welding is known to be conducted faster than other welding types. Since this type of welding maximises a continuously-fed electrode, it can effectively generate welds in a short time. MIG welding is even easier to carry out. Even for a complete novice, this type of welding can already provide great results since it is easy to learn and obtain proficiency.
Another great thing about MIG welding is it can provide high-quality welds. Since MIG is flux-free, industries do not expect its welds to be bombarded with entrapped slag. MIG welding does not even waste tons of welding sticks, which helps industries save a lot of time and money.
Ultimately, MIG welding can work with tons of metals and alloys. From aluminium to mild steel, it can cover almost all metals and alloys without any issues.
As for its drawbacks, MIG welding can be expensive at first. MIG welding is a valuable investment for manufacturers. However, they must shell out some money first during its set-up and installation. It can also be vulnerable to the effects of draughts and wind gusts, which may be present if the workshop is not sealed optimally. MIG welding likewise lacks portability as the machines used for this type of welding can be heavy and huge to bring.
Primary Applications of MIG Welding
No matter what its cons are, MIG welding can still be useful for many industries. The construction industry, for instance, uses MIG welding to create pipelines. Manufacturers of machines and pressurised vessels can even take advantage of MIG welding. This type of welding can also be utilised in repairing and maintaining structures, ships, and vehicles. Lastly, MIG welding can be useful for hobbyists and home users who are creating various crafts.
