Underwater welding is a well-paid profession. It provides welders the opportunity to travel and adventure in the world. But it’s one of the most dangerous jobs around the globe. Many people don’t know why is underwater welding so dangerous, you can get an idea from the death rate of underwater welders. Underwater welders face various risks due to operating operations in cold, deep, and dark places. The injuries often lead to long-term disabilities and even cause death.

Underwater welding plays an active role in the maintenance and repair of fully or partially submerged marine structures and vessels. According to commercial divers and data from the world, underwater welders make money about $53,990 per year or $25.96 per hour. An annual income of an underwater welder ranges from $25,000 to $80,000. Here you can get the complete details of how much underwater welders make.

Also, keep in mind that most underwater welders did their job for 10 to 15 years on a commercial basis. There are many reasons behind it. Sometimes, they are affected by diseases by spending long hours in the deep sea. 

Why is Underwater Welding so Dangerous?

There are many reasons why underwater welding is a dangerous occupation. Welding in the bottom of the sea produces pressurized oxygen and hydrogen gas. There are huge chances of lethal explosion when both gases combine in concentrated amounts. Many underwater welders work hundreds of feet below sea level. Moreover, they have to face immense pressure at such depth of water in the sea.

There are also many other factors that make underwater welding dangerous, therefore it will lead you to think about it before adopting this profession. Before choosing underwater welding, you must know the life expectancy of underwater welders. Because it will help you to get a clear idea of whether it is the right profession for you or not. One thing that is vital for underwater is that they need to be very skillful at diving and welding. 

Underwater welding is considered a unique and rewarding profession, but it involves many risks. You can get an idea by underwater welders’ lifespan. According to US statistics, the underwater welder death rate is terrifying – almost one in six welders dies on the job (15%). From this, you can get an idea of how dangerous is an underwater welder job. Many other studies that were carried out in the US reveal that underwater welding is the most dangerous and deadly occupation.

What is the Life Expectancy of Underwater Welders?

Underwater welding is one of the riskiest works on earth. Therefore, underwater welders have a short life expectancy. Underwater welding may sound easy to outsiders, but an underwater welder knows how difficult it is. An underwater welding job can be risky work if you don’t have safety gears and complete knowledge about it. According to recent research, the average age of underwater welders is 35 to 40 years. 

The two most important variables of keeping welder-divers safe include proper training and safety regulations. We know that commercial diving is a dangerous profession.  But it’s necessary, just like topside construction. In 2014, the United States industry report was published and it showed that underwater welding is a risky occupation.

Underwater Welding Death Rate

Industry reports show that the underwater welding death rate has a high fatality rate estimated to be around 15%, making it 1000 times more dangerous than working as a police officer. That does not include the severe and permanent injuries the workers suffer. Underwater welding jobs offer the most attractive salaries because the field of work is inherently dangerous, with welders facing long-term health issues and injuries.

According to Occupational Safety and Health Administration (OSHA), the U.S records an average of 6 to 13 commercial dive fatalities every year. From these stats, you can get an idea about the life expectancy of underwater welders. I hope now you have a clear understanding of why underwater welding is more dangerous than other welding operations.

Risk of Underwater Welding

There are many risks associated with underwater welding, but here we mention some top of the risks that underwater has to face in their profession.

Risk as a Commercial Diver

Commercial divers are exposed not only to the possibility of drowning but also to a variety of occupational safety and health hazards such as respiratory and circulatory risks, hypothermia, low visibility, and physical injury from the operation of heavy equipment underwater. These are some of the reasons why underwater welding is so dangerous.

The most common injuries and causes of death were drowning or asphyxia due to inhalation of water, air embolism, and cardiac events. There are several other dangers also, some of which might be deadly, while others could have long-term consequences.

Drowning

Drowning can occur if an underwater welder’s gear component fails. Another cause of drowning is the flooding of the underwater welding helmet or the band mask. There are several other reasons behind the low life expectancy of the underwater welder. Divers may experience health issues that leave them unable to realize when they are in danger or being the victim of failed or damaged equipment. 

Wildlife Attacks

Even though underwater welders are rarely attacked by wildlife. But there is a possibility of encounters with sharks and other sea creatures that might be deadly. So, it is vital for an underwater welder to keep all safety equipment with him. 

Hypothermia 

When the body is subjected to a low temperature underwater, the cold water conducts heat away from the body. The loss of heat can cause organ failure if the body remains cold for too long. Wearing a proper underwater dress protects the body from these exposures. 

Electrocution During Underwater Welding

For underwater welding, most operators used heavy welding equipment and flame. Therefore, there are huge chances of electric shock. Electrocution is another type of accident that may happen during underwater welding. Water provides little resistance to electricity. In this way, current flows freely from ungrounded sources. The welding arc may be unstable and uneven in freshwater and doesn’t make contact with the metal when wielded.

The risk of electric shock is significant if an unskilled diver is dealing with the arc. The workers who work in shallower water face less risk than those who work in deeper water. Therefore, it is recommended to use proper equipment while underwater welding, such as double pull switches, waterproof electrodes, etc. The most important thing before driving is that equipment should be used and tested. These safety measures help to increase underwater welders’ lifespan.

Risk of an Explosion 

The configuration of gaseous pockets from combining oxygen and hydrogen gases can lead to an explosion. These pockets create a sound that oxygen and hydrogen accumulate with each other. In this situation, a welder needs to find the location from where the gases are coming. Immediately stop working on it and move himself to a secure place

Here are some rules to save from explosion 

  • If possible, weld from highest to lowest point
  • In a gaseous environment, electrodes exceed ten thousand degrees Fahrenheit and explosives may occur if it sparks.
  • Look at those parts where gas is overhead and needed, use a vent tube to the surface.

Environmental Hazards

 While doing the operation, underwater welding affects the sea ecosystem in many ways. It involves 

  • Surges in a wave movement.
  • Rough water conditions
  • Poor visibility caused by water conditions 
  • Strong currents.

Some of the deepest depths underwater may be down to 2500m. This depth may expose the divers to a host of potential like

  • Nitrogen narcosis 
  • Hypothermia 
  • Increase in air consumption 
  • Decompression sickness 
  • Reduced visibility
  • Slower buoyancy compensator response

Decompression Sickness

The partial pressure of the nitrogen in breathing gets hired, when the wielder goes down underwater. The human body doesn’t use metabolic activities, so the gas is saturated as tissue. The welder ascends quickly from high-end to low-end pressure. The nitrogen comes out from the tissue. This can cause bubbles into the tissue and chunk the vessel of blood and may lead to death or paralysis attack. When the diver ascends to the surface too quickly, this condition may occur to avoid these conditions.

Underwater Welding Process

In underwater welding, the process usually refers to the wet welding capability where no barrier cuts the welding area from the water. It is also known as submerged in the water of the welding arc. During installation, pipelines, drilling rigs, Normal usage, and collision are unpredictable. Any repair work is required by using underwater welding due to any failure of the element. Underwater welding is difficult because defects are difficult to detect.

The welder maintains the following parameter for the upcoming welding 

  • Maintain the length of the cable.
  • Read the voltage of the open and closed circuit from the voltmeter.
  • Read the welding amperage from the tong meter.

Conclusion

Underwater welding is a very difficult and dangerous occupation. It provides the opportunity for travel and decent wages.  Mostly it causes death, it is perfect only for those who are heavily skilled in this field. There are many causes of death during underwater welding but drowning and electrocution are the main causes of death.  The death rate in underwater welding is around 15%. I hope now you a clear idea of why is underwater welding so dangerous.

Therefore before choosing this occupation, you must know how dangerous is underwater welding. If you agree to take a risk in life, you can earn a lot of bucks. It is always recommended to go through proper training. It is always recommended to use a top-quality underwater welding helmet and other safety gear. Because safety equipments are vital for all kind of welding operations, especially for underwater welding.
