What is are MIG welders?
When most imagine welding, they think of the combination of two pieces of metal together, and that’s about it. However, welding is a huge profession with many different aspects of welding – and welder – niches. One of those is MIG welding, which is completed by a MIG welder.
MIG Welding Explanation
MIG is the short form for Metal Inert Gas. It is a procedure whereby a MIG welder uses a tungsten electrical conductor to produce the weld. This type of welding is also referred to as Gas Metal Arc Welding, or MTAW. Don’t be thrown if you hear this expression. It’s still MIG welding.
The Job of a MIG Welder Explained
The MIG welding process is quite interesting, requiring a accomplished MIG welder to properly complete it. As stated above, MIG welding uses a tungsten electrical conductor to produce the link.
MIG welding is a form of arc welding. It is so because the heat produced in MIG welding comes from an electric “arc” that is maintained between the tungsten electrode and the piece that is being welded.
A MIG welder is a highly sought after expert because the process can be hazardous. For example, a MIG welder must know how to influence the heat input when welding so as not to create a slag or splatter. This can be done by foot or hand amperage controls.
Another key factor that makes MIG welding so hazardous is that there is a steady power current in MIG welding. This is one of the reasons it requires a extremely-clean surface for working.
For all of these reasons and quite a few more, a MIG welder must be thorough and organized in how he mans his workplace.
The Birth of the MIG Welder
MIG welding became fashionable during World War II, when aircraft and other war equipment was being churned out en masse. Primarily driven by the aircraft industry during this time, because of the competence of it, it quickly expanded to other industries – eg, construction.
