What Is MIG Welding?

What is MIG Welding? MIG (Metal Inert Gas) welding is one of the most common methods used today for joining and welding pieces of metals together. Welding by use of a gas metal arc, sometimes called by its other subtypes electric inert gas welding, is a method in which an electrical arc is formed between the workpiece and a suitable non-magnetic, consumable MIG coil or electrode, which fuses the workpiece so that they join together. A MIG welder has the ability to weld both thicker and thinner materials and is often used in conjunction with tig and stig welders for welding thick sheet metal and stainless steel.

How is it Different from Arc Welding? Arc welding is one of the oldest welding processes still in use today. It involves feeding a steel rod into a tungsten inert gas source, such as a nitrogen-filled cylinder; the rod is then heated via electric current supplied by a welding generator. The consumable metal electrode is then fed into the metal and the entire procedure creates a hot arc which feeds gas (usually nitrogen) into the weld puddle.

MIG welding combines this method with the ability to control the electrode feed by using a separate wire. The wire can be pushed down through the gas and plasma formed by the arc or drawn up through a shielding plate keeping the workpiece from the corrosive gases. This allows us to place the welding work in any location within the confines of a workbench or fabrication area.

When MIG welding is used in conjunction with a tig or stig welder, the process can be made even easier. A big and six are equipped with an arc which is designed to hit the workpiece only but not touch it; this is to prevent stray arc energy from creating arc flash and causing puddles in the weld puddle. When working with a combination of an electrode and workpiece, the weld operator can use either wire feed to feed the work into the weld, or use both feeds simultaneously.

There are several types of MIG welding: single-action and dual-action. In a single-action weld, the welder controls the electrode and workpiece at the same time. When a weld is completed, only one half of the arc is produced; this is because only the welding chamber and the electrode are in the chamber. The half-controlled process means that if a mistake is made, the arc will stop and allow the complete arc to be produced, or the filler metal to cool and harden while the filler metal is allowed to cool.

Dual-action welds the welder simultaneously feeds the weld into the work, and also controls the arc. Because the welder controls both the weld and filler metal at the same time, this type of weld produces fewer welds than a single-action weld. This is because the welder breaks the weld in half, which allows the two pieces of metal to move around and join together where they touch. By combining a single-action and dual-action method of welding, a welder can increase the amount of welds he can make per sitting, which can improve his production efficiency.

If you are a hobbyist, and are interested in learning what is mig welding, you should take the time to check out a class. You will learn what you need to know to complete a successful welding project and will gain the necessary experience to take on more challenging projects. Although you may not feel comfortable in the equipment, you will soon find that this line of work is easy to learn and is very rewarding. In addition, once you have become more skilled, you may be able to take on other metal fabrication jobs, which will give you even more time to enjoy your hobby.

The MIG welder’s torch does not actually strike the metal with its heat. Instead, the arc it generates is the source of the welder’s heat. This makes it ideal for using in places that would otherwise be difficult to weld, because the arc is already present. The welder has the advantage of being able to weld thicker materials, which is one of the reasons it is so commonly used. It is also a great choice for use with electric arc welding (AFL).
