When it comes to welding, ‘what type of welding is there?’ is perhaps one of the most frequently asked questions. There are a staggering 40 types of welding processes and techniques used by metalworkers and welders around the world.
Each one has its own set of advantages and applications. In 2017, it was estimated that the global welding equipment market was worth over $
3 billion, with diesel welders alone amassing nearly $450 million. So what exactly is welding and which techniques are most commonly used?
Let’s take a look at the different types of welding and their unique characteristics.
What Type of Welding Is There?Welding is a process that is used to permanently join two pieces of metal together. It is a process that has many different types, depending on the materials being joined, the process used, and the desired outcome.
In this blog, we discuss different types of welding and their applications.
Gas Metal Arc Welding (GMAW)GMAW is a form of welding that is commonly known as “MIG” welding.
It uses a welding gun to feed wire through the gun, onto the weld area. A current is then used to heat the wire and create the weld.
GMAW is a preferred choice when welding a variety of metals and requires minimal setup time and equipment.
Gas Tungsten Arc Welding (GTAW)GTAW is also known as “TIG” welding and is used for welding thin materials and precise joints. It uses a non-consumable tungsten electrode to strike an arc between the workpiece and the electrode, creating a heat source for welding.
GTAW requires more skill and experience than GMAW, but offers higher quality welds.
Shielded Metal Arc Welding (SMAW)SMAW is also known as “stick” welding and is the simplest type of welding process. The welding rod, or electrode, is placed against the workpiece to create an electrical current through the metal.
This current then creates an electric arc, which is used to heat the metal and create the weld.
Flux-Cored Arc Welding (FCAW)FCAW is a welding process that uses a continuous, tubular wire with flux in the center to produce a weld.
This flux helps to create a strong, sound joint by shielding the weld from atmospheric contamination and creating a slag layer to protect the weld from oxidation.
