Mig Welding Overview

There are many types of welds that are available today and MIG is one of those types. This type of welding goes back to 1940 when it was discovered to welding aluminum and other non-ferrous metals.

Many people refer to MIG welding as GMAW or gas metal arc welding. Often these two terms are interchangeable. This type of welding is considered automatic or semi-automatic, because it happens quickly. The process is to join two pieces of metal by continuously passing a wire through a welding gun. The wire is connected to a direct current and then passed through the gun with an inert gas like Argon.

The wire acts as an electrode and the inert gas acts as a shield when welding is performed. This means that the contaminated air be charged instead of the weld zone.

MIG welders will use this method to metals reporting faster than stick welding ordinary especially if they want soft metals like aluminum welding. This method was first began with the inert gas was too expensive to do the process all the time. Today, carbon dioxide can be used instead of the more expensive gas and makes this method more cost effective.

Advantages of MIG Welding

There are several advantages of MIG welders:

* It is faster than the traditional methods of welding and produces more continuous welding.

* It produces a cleaner weld with less splatter.

* It can be used with a wide range of alloys and metals, making it a versatile process elder.

Disadvantages of MIG welding:

Although this is a very specialized process that works efficiently for many projects there are a few drawbacks such as:

* The welding equipment is complex and extensive use.

* The equipment is a source of continuous power and a constant feeding of the wire through the gun.

* It is a very different process than traditional welding so there is a learning process for all welders using this technique.

* Because of the inert gas MIG welding does not use an open field, the gas because the wind would cause more problems for the MIG welder.

MIG welders is very significant in many industries due to its ability to rapidly weld metal. You see this form of welding is done in many industries and the automotive industry include nuclear.
