MIG Welding Machine is used to weld metals thicker than 1⁄4 inch. It is making use of inactive gas to protect the atmosphere. The MIG welder consists of maintaining a consumable electrode arc of solid wire and the piece to be welded. The use of this machine has been increasing due to requests from companies because it allows them to lose minimal amounts of materials, increasing productivity levels.
Application of the MIG welding machine:
It can be used to weld various materials such as carbon steel, stainless steel, aluminum, etc. Its productivity has a high percentage of efficiency, given the capacity of performance by a continuous electrode, which does not need to be changed with a higher relief rate than the others, allowing long and continuous welding.
Process for a MIG welding machine:
There are three basic processes and different from each other. We have the transfer by “short circuit”, “globular”, “transfer”, and “sprayed arch”.
– It transfers by a short circuit which is known as a short act. The metal change happens when an electrical short circuit is determined.
-Globular transfer process by which the metal droplets which are too large to sink by the force of gravity.
– Transfer by sprayed arc: occurs when a metal molten small drop extracted from wire tip and projected towards the welding.
Advantages of using the MIG Welding Machine:
They are recommended because of their ease of operation because they produce large manufacturing rates for their performance.
Welding instruments such as cables and guns are light making it easier to transport and manipulate for the operator. They are very versatile in terms of the variety of metals and fusions that can be used.
Recommendations for the use of the MIG welding machine:
- Have the safety equipment ready to help keep your body covered by preventing exposure to ultraviolet rays.
- Choose a MIG gun that is comfortable, these can be cooled by water or air.
- Prepare the area where you are going to weld, avoid having flammable materials nearby and look for a good surface to be able to weld.
- Get the right thread, making sure it is the same material to be welded. For example, if you are going to assemble stainless steel, use a stainless steel wire.
Today, the MIG welding machine is used in many applications within workshops and factories as well as by many people who have as a pastime the decoration or maintenance of the home and, of course, by all those passionate about welding.
