Welding is a metal fabrication process of joining two pieces of metal together by means of heat. It creates a strong and lasting bond between two pieces of metal and it also has the benefits of having a clean and polished finish. While a seemingly simple process, it is a highly skilled profession which requires certified welders to perform. There are several different types of welding. The ones we use here at Paragon Metal Fabricators are: MIG and TIG.
MIG Welding is also known as Gas Metal Arc Welding (GMAW). In this type of welding, two metals are heated by means of an arc which is created between continuously fed electrically charged wires and the surface of the material to be welded. The wires that carry the current through the welder torch are what is used to heat up the material. To protect the molten metal from reacting to outside elements, a shielding gas is used. This is one of the more common welding methods used since just about any type of metal can be welded by it. MIG is not more beneficial than other methods of welding, but it is one of the fastest and cost effective methods.
TIG welding is also known as Gas Tungsten Arc Welding (GTAW). Rather than having a constant wire being threaded through the welding tool (MIG), this method uses a fixed electrode as well as welding rods in order to fuse two metals together. The TIG Welding method is a much slower method compared to MIG, but it produces much more precise and aesthetically pleasing results while also creating a much stronger bond.
