Underwater welding has garnered legendary status in the world of engineering, allowing welders to tackle challenging projects in some of the harshest environments. Despite its impressive capabilities and well-deserved reputation for strength and precision, underwater welding carries inherent risks that should not be ignored when considering this career path. In this article, we will explore these risks while also examining how robotic arm technology is revolutionizing underwater welding and making it safer than ever. By gaining a comprehensive understanding of the hazards involved in this high-stakes profession, you will be better equipped to make an informed decision about pursuing a career in underwater welding.
The Basics of Submerged Welding
Submerged welding entails using specialized tools and techniques to weld materials underwater. This technique proves invaluable in repairing ships, pipelines, and other submerged structures, as well as constructing offshore oil rigs. Divers involved in this work must don heavy-duty gear, including neoprene or rubberized fabric gloves and helmets, to protect themselves from extreme temperatures and pressure.
Hazards Associated with Underwater Welding
Underwater welding is an extremely risky occupation, presenting a long list of potential dangers. These hazards include:
- Electrical shock resulting from contact with underwater electric currents.
- Toxic fumes generated when welding occurs in confined spaces.
- Heat stress caused by the extreme temperatures produced during welding.
- Fire or explosion risks when welding in highly flammable environments, such as oil rigs.
- Injuries resulting from poor visibility or restricted maneuverability underwater.
- Decompression sickness caused by rapid pressure changes during deep dives.
Notable Accidents in Underwater Welding
- Entanglement and entrapment – The tight spaces often involved in underwater welding can lead to entanglement or entrapment from cables, hoses, or other equipment.
- Electrical shock – Water seepage into the electrical system poses a common risk in underwater welding, often resulting in electric shocks.
- Burns – Due to intense heat and sparks, welding underwater can lead to severe burns on exposed skin or clothing.
- Crushed limbs – If proper safety protocols are not followed, heavy tools used in underwater welding can slip and crush an arm or leg.
- Leaks – Insufficient welding seals can result in leaks that may go unnoticed until the job is complete, leading to further hazardous conditions.
Enhancing Safety in Underwater Welding
Gradually, robotics and other advanced technologies are making underwater welding safer. For example, robotic arms can perform basic tasks such as surface cleaning or joining parts without endangering human divers. Additionally, remotely operated vehicles (ROVs) and other new tools allow welders to monitor their progress from a distance and even take over certain operations when required. These technological advancements are making underwater welding progressively safer, although the occupation will always carry a degree of risk.
How to Pursue a Career in Underwater Welding
Becoming an underwater welder requires specialized training, certifications, and experience. Starting with a welding apprenticeship or certification program, such as those offered by the American Welding Society (AWS), is crucial. Subsequently, gaining experience in welding both on land and underwater is essential. Divers planning to use their skills underwater must undergo specialized training, covering everything from basic skills like buoyancy control to advanced techniques like welding at depth and managing mixed-gas dives. To become a certified underwater welder, passing the AWS Underwater Welding Certification Exam is necessary.
Helpful Tips for Underwater Welding
