Welding is the process of joining two or more metal parts using pressure, heat, or both. It’s used to create and repair all kinds of equipment across a wide variety of industries, including agriculture, construction, and manufacturing. However, there are several different ways to create a weld, each with unique benefits. To determine which method your job requires, use this helpful guide.

3 Common Types of Welding

1. Metal Inert Gas (MIG) Welding

For this method, a consumable wire electrode is continuously fed through the welder along with a shielding gas. The gas protects the metal from oxygen and other environmental contaminants that would prevent a proper weld. This method typically emits fewer fumes and requires less heat than other methods. It’s often used in construction, fabrication, plumbing, and automotive and maritime repairs.

2. Arc Welding 

Like MIG welding, this method also feeds a consumable wire electrode through the gun. However, the wire features a flux core that creates a gas shield, meaning the welder doesn’t need to use an external shielding gas.

Thus, this method requires fewer materials and less energy than other welds. It’s also the best option for rusty materials. Because this process uses a lot of heat, it should only be used for durable, thick materials that can withstand high temperatures, such as heavy steel machinery. 

3. Tungsten Inert Gas (TIG) Welding

For this technique, the weld is created by heating and melting the metal with a tungsten electrode. This type of electrode is non-consumable, which means it can survive extreme heat.

Many welders regard this method as the most difficult. However, it produces the strongest, most precise results, which is why it’s used for critical projects like vehicle manufacturing and aerospace construction. It’s not recommended for materials coated with dirt or rust.
