What Is Underwater Welding Called?

Underwater welding can be a difficult activity and one of the most challenging welding professions. People who become involved in this field have to be highly trained and have a good understanding of the techniques.

With the help of high-tech equipment, underwater welders take on important tasks involving the maintenance of oilrigs and the creation of metal structures for a variety of projects. More than 3000 workers around the world engage in underwater welding, performing more than 100,000 dives per year to work on oilrigs and construct vessels. So, what is underwater welding called?

Let’s find out!

What is underwater welding?

Underwater welding is a specialised construction technique used to weld and cut metal underwater. It is a highly specialised and potentially hazardous job that requires specialised training.

It is used to weld and repair underwater structures such as pipelines, platforms, ships, etc.

Why Is Underwater Welding Necessary?

Underwater welding serves two main purposes. Firstly, it is used for repairs and new construction of ships, oil pipelines, fish farms, ocean liners, bridge columns, and more.

Secondly, it is used as a preventative measure to strengthen and protect these structures from future damage.

What Are The Benefits Of Underwater Welding?

Underwater welding offers numerous benefits.

It can be conducted quickly and effectively without the need to dry or clean the area. Also, welding and repairing underwater eliminates the need for expensive or difficult lifts out of the water.

Additionally, underwater welding eliminates the risk of sparks or heat causing environmental damage because it can be conducted in low light for safety. The low light also helps with the efficiency of the weld because there is no need for large complex shielding equipment, making it a more cost effective welding process.

What Is Underwater Welding Called?

Underwater welding is commonly referred to as “hyperbaric welding”. This term describes the welding process which is conducted at a higher pressure than normal atmospheric pressure.

Safety Considerations Of Underwater Welding

Underwater welding is a highly specialised technique and requires a wealth of knowledge and experience. It is important to consider that sparks and unusual amounts of heat can cause potential hazards to the Welders and to the environment. To ensure safe practices, Welders must wear the appropriate safety gear and maintain high-level safety conditions throughout the welding process.
