Sickness: Welders risk decompression sickness (DCS) if they ascend too quickly after welding.
Electric shock: Welders are at risk of electric shock if they come into contact with live electrical circuits.
Environmental hazards
Underwater welding also poses many environmental hazards. These include:
Underwater currents: Welders risk being swept away by underwater currents.
Limited visibility: Welders are at risk of not being able to see what they are welding due to limited visibility underwater.
Marine life: Welders risk encountering dangerous marine life, such as sharks and stingrays.
Psychological hazards
The psychological hazards of underwater welding include the following:
Stress: Welders are under a great deal of stress due to the dangerous nature of the job.
Isolation: Welders are often isolated from other people for long periods.
Is underwater welding The most dangerous job?
Underwater welding is considered one of the most dangerous jobs due to the unique hazards of working underwater. The risk of drowning, electric shock, and fire or explosion are all significant risks that you must train welders to handle. In addition to these risks, welders may face physical challenges such as hypothermia and the need to move around in heavy diving gear.
However, it is essential to note that many other dangerous jobs exist in various industries. For example, employment in the construction and mining industries, as well as jobs in the commercial fishing industry, are also considered to be high-risk. These jobs may also involve heavy machinery, heights, hazardous materials, and other safety risks.
It is also worth mentioning that even though it can be dangerous, underwater welding is also essential, as it allows for the maintenance, repair, and construction of ships, oil rigs, and other submerged structures.
Does underwater welding shorten lifespan?
It is not clear if being an underwater welder necessarily shortens lifespan. However, the job has certain health risks that may impact an individual’s overall health and well-being.
One of the main concerns is the risk of decompression sickness (DCS), also known as the bends, which can occur when a diver ascends too quickly after spending time at depths. It can cause joint pain, paralysis, and even death if not treated promptly.
Another concern is the risk of lung damage due to breathing compressed air for extended periods. It can cause pneumothorax (collapsed lung) and lung barotrauma.
Working underwater can also expose welders to toxic gases and other hazardous materials, which can have long-term health effects.
Future of Underwater Welding
As technology continues to advance, the future of underwater welding looks bright. One of the key developments in the field is the increasing use of remotely operated underwater vehicles (ROVs) for welding tasks. These vehicles are equipped with advanced sensors and cameras, allowing welders to perform their work remotely from the surface. This technology makes the welding process safer and allows for more precise and efficient welding.
Another area of innovation in underwater welding is using hybrid welding techniques. These techniques combine traditional welding methods with newer, non-destructive technologies such as ultrasonic and laser welding. It can result in more robust, durable welds with minimal damage to the surrounding structure.
Automation and robotics are also becoming more prevalent in underwater welding. Robotic systems can be programmed to perform specific welding tasks, such as welding in hard-to-reach areas or harsh environments. It can help to increase productivity and reduce the risk of accidents.
The increasing use of renewable energy sources such as wind and solar power also drives the demand for underwater welding. As more offshore wind farms and ocean-based solar power systems are built, welders will be needed to install and maintain these structures.
How do underwater welders not get electrocuted?
There are several ways that underwater welders can prevent electrocution while working. Some of the key measures include:
Using specialized welding equipment
Welders must use equipment that is specifically designed for use in an underwater environment. High-voltage currents typically power this equipment, and it must safely handle these currents to avoid the risk of electrocution.
Grounding the workpiece
Welders must ensure that the workpiece they are welding is adequately grounded. It helps to prevent electrical current from flowing through the welder’s body.
Using a dry environment
Welders must work in a dry environment to avoid the risk of electrical shock. It is typically achieved using a dry suit or a diving bell to keep the welder dry.
Using a safety rope
Welders must use a safety rope to quickly and safely pull to the surface in an emergency.
Proper training and procedures
Welders must receive specialized training in properly using welding equipment and safely handling electrical currents. They must also follow appropriate safety procedures to minimize the risk of electrocution.
Using a specialized underwater welding power source
These power sources are designed to work underwater and protect against electrical shock. They are equipped with over-current protection, meaning the power source will shut down automatically in case of a short circuit.

Do underwater welders get attacked by sharks?
While underwater welders can encounter sharks, it is considered a rare occurrence. Sharks typically avoid areas with a lot of human activity and noise and are not naturally attracted to the bright lights and sparks associated with welding.
However, it’s important to note that welders work in different environments. Some of them, such as shipwrecks, oil rigs, or offshore platforms, may be located in areas where sharks are more common. In these cases, welders are trained to take the necessary precautions to avoid potential shark encounters.
Precautions include, but are not limited to:
- Knowing the shark activity patterns of the location where the work is taking place.
- Using shark shields, which emit an electric field to deter sharks.
- Avoiding working in areas known for shark activity during certain times of the year.
- Having a plan in case of an encounter.
Is underwater welding hard on your body?
Underwater welding can be physically demanding and negatively affect the body if proper precautions are not taken. The combined effects of high pressure, cold water, and heavy equipment can lead to hypothermia, decompression sickness, and cardiovascular strain.

One of the main benefits of underwater welding is the high earning potential, as it is considered a highly skilled and specialized profession with a high demand in specific industries.
What type of welding is Used underwater?
The most common type of welding used underwater is Shielded Metal Arc Welding (SMAW), also known as “stick welding.” This method uses a consumable electrode coated in flux to shield the weld from the surrounding water. The arc is struck between the electrode and the metal, creating a weld. The flux coating on the electrode also produces a slag that must be chipped away after the weld is complete.
Gas Tungsten Arc Welding (GTAW) or Tungsten Inert Gas (TIG) welding is also used underwater. This method uses a non-consumable tungsten electrode to create the arc, and a separate filler metal is added to the weld. This method is considered more precise and requires more skill to perform.
Gas Metal Arc Welding (GMAW) or Metal Inert Gas (MIG) welding is also used but is less common due to the difficulty in keeping the equipment dry and the shielding gas flowing correctly.
