Gas Metal Arc Welding (GMAW) Certificate

Certificate offered as: Workforce

GMAW stands for gas metal arc welding, also known as MIG (metal inert gas) welding.

Like all welding, it is a technique used to join two metals. Just like you use nails to join two pieces of wood or mortar to hold bricks together.

You'll find GMAW (MIG) is one of the easiest welding processes to learn and master. You are likely to enjoy it for its speed, too! If you were learning to drive a car, GMAW (MIG) would be like driving an automatic.

Industry Information

How does GMAW (MIG) work?

Like other welding techniques, in gas metal arc welding (GMAW) an electrode wire is inserted into the welding torch. Once the motor is turned on electricity flows from the motor, through this electrode wire – the conduit – to finally arrive at the metal the welder is working with.

What is unique about GMAW (MIG), however, is the electrode wire is fed automatically to the welding torch. The welder does not need to use both hands at the same time.

Because of the automatic wire feed, GMAW (MIG) is the easiest welding process to learn. All you need to do is pull the trigger on the welding torch - how efficient! GMAW (MIG) also produces a cleaner final product. Just be sure to listen in class about how to set up and maintain the machine properly. That is critical for mastering this welding process.

What types of metals can I weld with?

GMAW (MIG) is great for welding with the following metals: aluminum alloys, steel and stainless steel.

Career Information

What kind of jobs can I find with GMAW (MIG) skills?

You’ll see GMAW (MIG) used in the manufacturing industry and auto body work. Also, like shield metal arc welding (GMAW), gas metal arc welding (GMAW) is commonly used in pipe fabrication.
