When versatility is required and speed of importance, welders turn to MIG (metal insert gas) welding. It’s one of the most common forms of industrial welding and is sometimes performed automatically by automation rather than by hand. MIG welding is a form of arc welding that uses a shielding gas to protect the weld area while it’s being welded.

Why do we need MIG welders?

MIG welding machines are highly versatile and can be used to weld a variety of metals, which has made it highly popular in the industrial area for speed of application. They’ve been in continuous development since they were first invented and there are now a number of different variations of MIG welders, such as synergic/pulse machines using a variety of new innovation like coldMIG and highPULSE. It is the most simplest of welding processes and is easy to perform, making it user friendly and productive. Westermans specialise in used and refurbished heavy duty MIG Welders. View our current stock or above or give us a call today.   We need to continually source Used MIG welding equiment. Give us a chance to buy any MIG welders you are disposing of before you sell or part-exchange. We pay good prices.

MIG Welding

MIG stands for Mechanised Inert Gas Welding and is the most simple form of welding. Gas Metal Arc Welding (GMAW) is frequently referred to as MIG welding. MIG welding is a commonly used high deposition rate welding process. Wire is continuously fed from a spool. MIG welding is therefore referred to as a semiautomatic welding process.

MIG Welding Benefits

All position capability
Higher deposition rates than SMAW
Less operator skill required
Long welds can be made without starts and stops
Minimal post weld cleaning is required

MIG Welding Shielding Gas

The shielding gas, forms the arc plasma, stabilizes the arc on the metal being welded, shields the arc and molten weld pool, and allows smooth transfer of metal from the weld wire to  the molten weld pool. 

Want to know how and why MIG welding developed and works?

This is a basic guide on how to weld using a metal inert gas (MIG) welder. MIG welding is the process of using electricity to melt and join pieces of metal together. MIG welding is sometimes referred to as the "hot glue gun" of the welding world and is generally regarded as one of the easiest type of welding to learn.

Think of this as a guide to get you started MIG welding. Welding is a skill that needs to be developed over time, with a piece of metal in front of you and with a welding gun/torch in your hands. There are many online tutorials, youtube videos and forums to help you develop into a MIG welder.

MIG welding was developed in the 1940's and 60 years later the general principle is still very much the same. MIG welding uses an arc of electricity to create a short circuit between a continuously fed anode (+ the wire-fed welding gun) and a cathode ( - the metal being welded). 

The heat produced by the short circuit, along with a non-reactive (hence inert) gas locally melts the metal and allows them to mix together. Once the heat is removed, the metal begins to cool and solidify, and forms a new piece of fused metal.

A few years ago the full name - Metal Inert Gas (MIG) welding was changed to Gas Metal Arc Welding (GMAW) but the name MIG welding is still commonly used around the world.

MIG welding is useful because you can use it to weld many different types of metals: carbon steel, stainless steel, aluminium, magnesium, copper, nickel, silicon bronze and other alloys.

See this very basic but thorough video demonstrating the start to finish of joining two pieces of metal using the MIG welder - the fastest, easiest and simplest form of welding machine available today.

Here are some advantages to MIG welding:

The ability to join a wide range of metals and thicknesses
All-position welding capability
A good weld bead
A minimum of weld splatter
Easy to learn

Here are some disadvantages of MIG welding:

MIG welding can only be used on thin to medium thick metals
The use of an inert gas makes this type of welding less portable than arc welding which requires no external source of shielding gas
Produces a somewhat sloppier and less controlled weld as compared to TIG (Tungsten Inert Gas Welding)
