Advantage Fabricated Metals performs a number of welding processes. The two most common welding processes we use include TIG, an acronym for Tungsten Inert Gas welding and MIG, an acronym for Metal Inert Gas welding. TIG is also referred to as GTAW (Gas Tungsten Arc Welding) and Heliarc®. MIG also is referred to as GMAW (Gas Metal Arc Welding). We also provide oxy-acetylene welding.
The "Metal" in Gas Metal Arc Welding refers to the wire that is used to start the arc. It is shielded by inert gas and the feeding wire also acts as the filler rod. MIG is fairly easy to learn and use as it is a semi-automatic welding process.
Characteristics of the MIG welding process
The illustration that follows provides a look at a typical MIG welding process showing an arc that is formed between the wire electrode and the workpiece. During the MIG welding process, the electrode melts within the arc and becomes deposited as filler material. The shielding gas that is used prevents atmospheric contamination from atmospheric contamination and protects the weld during solidification. The shielding gas also assists with stabilizing the arc which provides a smooth transfer of metal from the weld wire to the molten weld pool.
Versatility is the major benefit of the MIG welding process. It is capable of joining most types of metals and it can be performed in most positions, even though flat horizontal is most optimum.
The most common welds are illustrated below. They include the:
MIG is used to weld many materials, and different gases are used to form the arc depending on the materials to be welded together. An argon CO2 blend is normally used to weld mild steel, aluminum, titanium, and alloy metals. Helium is used to weld mild steel and titanium in high speed process and also copper and stainless steel. Carbon dioxide is most often used to weld carbon and low alloy steels. Magnesium and cast iron are other metals commonly welded used the MIG process.
