What Is Spray Welding?

Spray welding has been around for more than a hundred years, and with more than 4500 patents, it’s a proven method of welding that helps create strong, durable joints. It is used in a variety of industries, from aerospace and automotive to medical implants and construction. Its popularity is growing as a cost-effective way to weld and its ability to complete complex welds quickly and easily.

With its application in so many different fields, it’s no surprise that the global spray welding market is expected to grow to more than 15 billion USD by 202

So what is spray welding and why is it gaining so much traction? In this article, we will explore more and provide an answer to the question, what is spray welding?

What Is Spray Welding?

Spray welding is a process of welding where metal is melted and fused together by applying an electric arc to specially prepared electrodes. It is also known as arc welding and is a quick and efficient welding method.

In many cases, it can be used in the production of large assemblies and structures such as vehicles and ships.

How Does Spray Welding Work?

Spray welding works by using an electric arc to heat and fuse metals together. The arc is created by using a welding rod that is connected to an electric current. A high voltage is then used to cause the arc to leap and generate a high temperature that’s enough to melt the metal.

Once the metal has melted, a spray of molten metal is used to bond the metals together.

Advantages Of Spray Welding

Spray welding has several advantages over other welding processes.

One of the main advantages is that it can join large sections of metal quickly and with minimum heat distortion. This makes it ideal for welding large objects like ships, cars and trucks.

Other advantages include:

  • It is a time-saving process as it eliminates the need for separate series of welding passes.
  • It is generally less expensive than other welding processes.
  • The process produces very little heat distortion, and often no post-weld heat treatment is required.

  • It produces highly durable welds.
  • It can be used to weld a variety of metals.

Disadvantages Of Spray Welding

While spray welding can be a great way to weld large objects, it has some disadvantages. One of the main disadvantages is that it has poor accuracy when it comes to welding smaller parts. For example, it is not an ideal welding method to make precise and small welds. Other disadvantages include:
  • The welding process requires high-levels of operator skill to ensure quality welds.
  • It is a messy process and can create hot splatters that can be dangerous in some situations.
  • The clamping procedure is more complex and more costly compared to other welding methods.
  • It requires large and costly equipment.


Spray welding is a welding method that can join large pieces of metal together quickly and with minimal heat distortion. It is generally less expensive than other welding processes, and produces highly durable welds. However, it has poor accuracy when it comes to welding smaller parts and requires large and costly equipment and high operator skill.
