MIG/MAG (Metal Inert Gas/Metal Active Gas) welding is one of the oldest and most popular welding techniques. It is a method of thermally processing metals that uses a shielding gas to mask the areas to be welded in order to achieve stable heat input and a controlled reaction. MIG/MAG welding is an important tool for industrial production. It is a simple and efficient process used in the manufacture of metal structures and components. Many different types of metals can be welded using this technique, including steel, aluminium, brass and copper. In MIG/MAG welding, a wire is used as filler material. The wire is pulled through a weld and then placed in a gas atmosphere to protect the weld. The shielding gas flow keeps the metal from being oxidized and improves the quality of the weld. There are different types of MIG/MAG welding machines. Some are manually operated while others are automatic. Choosing the right welding machine depends on the type of materials to be welded and the specific requirements. MIG/MAG welding has many advantages. On the one hand, it is a fast and efficient technique that ensures a high quality of the weld. On the other hand, the temperatures can be easily controlled in order to achieve optimal welding performance. In addition, the process is simple and inexpensive as it requires little equipment. MIG/MAG welding is a very versatile process and can be used for many different applications. It is one of the best techniques for welding metal components and is therefore an important part of industrial manufacturing.
