Mig Welding, GMAW, Gas Metal Arc Welding

Mig welding is a very economical welding process that is more efficient than other weld techniques.

Automated welding robots can be setup to do MIG with breath taking results. Welds so perfect and done so fast it is fascinating to watch. These robotic cells are used throughout the manufacturing world for car and truck manufacturers right down to the smaller job shop type engineering works.

It is also known as gas metal arc welding which is abbreviated as GMAW.

It is nothing more than the continuous feeding all of electrically charged wire which carries a current and a voltage to the welding puddle. Because it keeps feeding in and there is always in electricity there it is a never ending cycle. It will keep putting down filler material until the user lets go of the trigger.

It’s a preferred technique these days; here are few reasons for that:

1. Is reasonably simple to do.

2. Because it is always continuously feeding in the electrode it completes the job faster.

3. Is less expensive and more economical.

4. To increase productivity and throughput semi automated or fully automated devices can be fitted.

5. Has the versatility to be used with gasless wire or gas assisted wire.

The shielding gas provides you with better control over the spatter of the molten pool of metal that is created. A variety of gases can currently be selected for this type of welding.

Mild steel, stainless and aluminum are all easily welded using the mig welding process.

You can find a variety of machines that range in price, capabilities and size. In order for you to select the appropriate welder for your particular needs, the maximum thickness of the metal you will be working with must be determined.

I always like to say to people to buy a machine which is slightly more powerful than what they think are going to need to use right now. This way it sort of future proofs them for later on down the track when they need to tackle larger projects. I know it always happens to me, I go and buy something and then a few months later I say to myself gee I should have bought the bigger or better version.

So now that we have the power source unit selected you’re going to need to stock up on some basic consumables. Your consumables are things that are consumed over time thus the name consumables. You’re going to need to keep a small supply of items such as spare contact tips or contact tubes as they are called in the UK. Making sure that you use the correct size tip for the correct sized wire. Also you’re going to have to have some spare nozzles or shrouds, insulators, tip holders, gas diffusers and possibly a liner.

It is possible to mig weld stainless steel, aluminum, mild steel, high tensile steel and all other sorts of metals. But the most common welded materials are mild steel, stainless steel and aluminium as using the mig welding process makes it very easy.
