Commercial underwater welding is one of the most thrilling and high-paying careers in the world of skilled trades. However, this field also comes with its unique challenges and risks. Whether you’re considering diving into this exciting profession or are just curious, this article will walk you through everything you need to know about hyperbaric underwater welding and the different aspects of the trade. We’ll cover key topics such as types of underwater welding, the death rate, earning potential, and why most people can only pursue it for a limited period.
Introduction to Commercial Underwater Welding
Commercial underwater welding is a specialized field where welding is performed underwater, often in challenging conditions. This type of welding is necessary for many industries, including offshore oil and gas, shipbuilding, and underwater construction. However, what makes it truly unique is the combination of diving skills and advanced welding techniques.
What is Hyperbaric Underwater Welding?
Hyperbaric welding refers to welding at high pressure, often under water. The term “hyperbaric” is derived from the Greek word meaning “increased pressure.” When welding takes place underwater, the environment is much different from on land due to the water pressure and the need for special techniques to handle the unique challenges of the underwater world.
Types of Underwater Welding
Underwater welding is generally divided into two types: wet welding and dry welding.
Wet Welding
In wet welding, the diver performs the weld directly in the water. An electrode creates an electric arc between the metal and the welder, and although the area is submerged, the arc remains stable because of special equipment. Wet welding is more convenient and quicker than dry welding but comes with more risks, such as electric shock or exposure to harmful gases.
Dry Welding
Dry welding, on the other hand, involves creating a hyperbaric chamber around the weld site to remove the water. This is also known as hyperbaric welding and is safer than wet welding as it offers more control over the environment. However, it is more expensive and time-consuming to set up.
How Does Hyperbaric Welding Work?
Hyperbaric welding uses a sealed chamber, known as a habitat, where water is excluded so the welder can perform tasks in a dry environment despite being underwater. This method ensures a more stable and safer process, minimizing risks like contamination of the weld due to water or other impurities.
The Role of Commercial Divers in Underwater Welding
To become an underwater welder, you first need to be a certified commercial diver. This involves mastering diving techniques, handling complex tools, and learning to work in pressurized environments. Commercial divers are trained to withstand the high pressures of deep-sea environments and are crucial in projects such as repairing ships or pipelines.
Training and Certification Requirements
Becoming an underwater welder requires extensive training. First, you need to be certified as a commercial diver, which involves both classroom education and hands-on training. Then, specialized welding training is required to understand the intricacies of welding under extreme conditions. Certifications like the American Welding Society (AWS) and the International Marine Contractors Association (IMCA) are essential.
Risks and Dangers of Hyperbaric Welding
Underwater welding is an extremely dangerous job. Divers face risks such as drowning, decompression sickness (the bends), electric shock, and exposure to harmful gases. Poor visibility and strong underwater currents can make the job even more hazardous.
Hyperbaric Welding Death Rate
The death rate for underwater welders is a sobering statistic. Studies suggest that underwater welders have a fatality rate of around 1 in 200 workers, making it one of the most dangerous occupations in the world. This high-risk factor is largely due to the extreme conditions, equipment failure, and human error.
Underwater Welding Salary
One of the reasons people are drawn to underwater welding is the high salary.
Underwater Welding Per Hour
Underwater welders can earn anywhere from $25 to $80 per hour, depending on their experience, the project, and the depth at which they work. Welders working in hazardous or deep-sea environments tend to earn on the higher end of the spectrum.
Annual Earnings
Annually, underwater welders can make between $50,000 to $200,000, with some elite professionals earning even more. The more dangerous and remote the job, the higher the pay.
Why Can You Only Do Underwater Welding for 10 Years?
One of the most significant limitations of underwater welding is its effect on the body. Constant exposure to high pressure and dangerous conditions leads to long-term health risks. Most underwater welders retire after around 10 years due to the physical toll on their bodies, such as joint pain, lung issues, and nerve damage.
Essential Equipment for Underwater Welding
To safely and effectively perform underwater welding, welders require specialized equipment, including:
- Diving suits with insulation to protect from cold water.
- Welding electrodes designed for underwater use.
- Breathing apparatus and air supply systems for deep dives.
Industries That Use Underwater Welding
Several industries rely heavily on underwater welding, including:
- Oil and gas: Maintaining offshore rigs.
- Shipbuilding and repair: Fixing vessels and underwater structures.
- Civil engineering: Building underwater bridges and tunnels.
Safety Measures and Precautions
Given the high risks, underwater welders must follow strict safety guidelines. These include using state-of-the-art equipment, undergoing regular health check-ups, and adhering to decompression protocols to prevent the bends.
Future of Underwater Welding
As industries such as offshore oil and gas continue to grow, the demand for skilled underwater welders will rise. However, advancements in robotics and underwater drones may reduce the number of human welders needed in the future, making the profession more technology-driven.
