What are the differences between TIG and MIG welding?

 In news en

TIG welding is applicable to all types of metals, from steel or aluminum, to different alloys. It can also be used to weld thin gauge metals with improved strength and corrosion resistance finishings. Its gaseous protection system uses the heat of the electric arc between the electrode and the welded piece. In this process, a tungsten electrode is used, so the electrode is not consumed during the welding process. Therefore,  it requires a separate filler material in rod or wire format.


Moreover, TIG welding requires a very high level of technique from the welding personnel, that is why Boyfre ‘s team of professional experts is determined to guarantee the best finishing.


MIG welding was developed to weld non-ferrous materials. However, it is a process that is used in many other contexts, especially for small and medium thicknesses in steel and aluminum structures, due to the resistance of welding.


In MIG welding, a metal electrode is used, and in this case, it is consumed during the welding of parts as a filler material. Therefore, bead discontinuities and cutting times are reduced, ensuring a good finishing of the pieces.


Overall, there are different ways to apply TIG and MIG welding: manual, automatic or semi-automatic. MIG welding allows welding in any position, unlike TIG welding, which is used when the pieces are manufactured  sideways and then the job is finished with welding.
