Welding Process used at CMPL:

Gas Metal Arc Welding (GMAW/MIG)

Also known as Metal Inert Gas or MIG welding, this process uses a thin wire as an electrode. The wire heats up as it is fed through the welding instrument and towards the welding site. Shielding gas must be used to protect the weld from contaminants in the air.

Typically, this comes in the form of carbon dioxide, oxygen, argon or helium. Gas metal arc welding is believed to be one of the easier welding techniques to learn, which makes it a great area of focus for beginning welders.

Gas Tungsten Arc Welding (GTAW/TIG)

TIG welding uses a non-consumable tungsten electrode to produce the weld. You will still need an external gas supply, usually argon or a mix of argon and helium.

This is considered one of the most difficult welding methods to master, and one that produces the most high-quality welds.

Because there is only a tiny area between the arc and the area being welded, it takes an enormous amount of precision and skill to complete. Welds born of this method are known to be extremely strong.

Shielded Metal Arc Welding (SMAW)

This type of welding process relies on a manual technique using a consumable electrode coated in flux. This method tends to be most popular among home-shop welders. This process is also more informally known as stick welding.

The nickname references the electrode used to weld the metal, which comes in the form of a “stick.” Because shielded metal arc welding requires minimal equipment, it’s one of the most low cost processes around.

This type of welding does not require shielding gas and can be performed outdoors in the wind or rain. It also works well on dirt and rusty materials. That said, downsides do exist.
