Welding is an amazing process that uses electricity to melt and join pieces of metal.Welding is sometimes referred to as the “hot glue gun” in the welding world and is considered one of the easiest welding to learn.
New welders learning how to weld should start with metal inert gas (MIG) welding, also known as gas metal arc welding (GMW).
MIG is a type of electric arc welding that relies on creating an electrical circuit that passes through the material to be welded together and a welding wire that acts as an electrode.
When the welding wire touches the metal object, the circuit is complete. The wire is pulled back some distance and heated to thousands of degrees Fahrenheit, creating an electric arc that melts the wire and partially melts the two metals.
This creates a metal pool, where the three metals combine to cool and solidify, leaving a bead in the sealed seam.As the welding operation continues from the seam, the wire melts and more wire is continuously supplied from the edge of the welding gun. At the same time, a gas from the gun spreads around the arc to protect the sealed area from air pollutants such as oxygen and nitrogen.
The light produced by any type of arc welding is extremely bright. If you do not protect yourself, it will burn your eyes and skin like the sun. The first thing you need to weld is a welding mask.
I wear an auto-dark welding mask on the bottom. They are really helpful if you are going to do a bunch of welding and make a big investment if you think you will often work with metal.
Manual masks You need to use a free hand to drop the mask from your head or pull the mask down. This allows you to use both your hands for welding and not have to worry about the mask.Think about protecting others from light, and use a welding screen if available to build a border around you.
