Different Types of Welding And Their Uses

There are quite a few different types of welding, and every type has its own features, benefits, and drawbacks.

Welding is a process which is used to make a joint between surfaces by using heat and pressure. As the surfaces being welded cool down, a joint forms on it.

In this article, we’ll talk about some of the most commonly used types of welding in the industry, and their benefits and drawbacks.

Arc Welding

In arc welding, an arc of electricity is used to melt two metal surfaces, which can then be joined together. You’ll need an electricity connection to power the arc welder.

To stop oxidation at the point of welding, gases are used to keep the area safe.

This type of welding is used in making ships, in machines, automobiles and construction.

Arc welding requires less time to do, but it isn’t suitable for thin metals. You can learn online on how to become a professional welder.

MIG Welding

MIG welding uses an electric arc and inert gas to weld different metal surfaces together. You have to use an electrode which is melted and used in the welding pool.

MIG welding is suitable for welding sheets of metal together, and to join together steel structures.

MIG welding can also be automated with the help of machines, but it doesn’t work well on thick metals.

TIG Welding

TIG welding uses tungsten gas in the welding process. The electrode is non-consumable. A shielding gas is also used to keep the working area safe from oxidation.

A major advantage of TIG welding is that you can do it both on AC and DC power. What type of welding is used in the aerospace industry, and is known for its high-quality welds. However, the process is very difficult to master, and requires lots of time as well.
