TIG and MIG/MAG welding
The acronym TIG stands for Tungsten Inert Gas.
TIG welding is a welding process in which heat is created by forming a plasma arc between a tungsten electrode and the workpiece. TIG welding is primarily used for thin sheets of aluminium and stainless steel, but can also be used for ordinary steel. TIG welding can achieve a very high quality weld. In addition to this, the TIG welding process is excellently suited for application of base coats. In TIG welding, the wire is fed manually, which requires a highly skilled welder.
The acronym MIG/MAG stands for Metal Inert Gas/Metal Active Gas.
MIG/MAG welding actually is two welding processes that are very similar to one another. Because the only difference between the two is the gas that is used, they are often regarded within the welding community as one and the same welding method.
MIG/MAG welding is a welding process in which a wire is fed continuously and mechanically during welding. A plasma arc is formed between the wire and the workpiece. One the one hand, the wire serves as an electrode and on other hand, it is melted off and serves as an additive.
