Underwater welding is one of the riskiest careers in the industry, as the conditions make it inherently hazardous. When underwater welding is performed, an arc is created between the workpiece and the electrode. This produces an intense flame, extreme heat, and a bright light. On top of that, the welders must contend with a lack of gravity and a shortage of oxygen. As a result, underwater welders find themselves in a rather dangerous situation.
Underwater Welding and Risks:
- The first major risk of underwater welding is the possibility of electric shock. Because of the arc needed to weld underwater, welders are exposed to dangerously high levels of electricity. This can cause injury or even death, so special care must be taken to ensure that welders are operating in an environment with proper grounding and adequate insulation. Additionally, numerous safety precautions must be taken to protect the welder from an electric shock, such as dry suits, gloves, boots, safety harnesses, and other types of insulation.
- The second risk of underwater welding is radiation. Protective clothing, such as lead aprons, is required to shield the body from harm. However, exposure to harmful UV and IR radiation during underwater welding can still be dangerous, as it can cause skin burns, eye injury, and other health issues. Additionally, underwater welding produces intense light that can cause temporary or permanent loss of vision.
- The third risk of underwater welding is fire and explosion. Welders may come in contact with flammable tanks and pipelines underneath the surface, and the heat generated by the welding arc can cause those materials to ignite. Welders must be especially careful with the safety valves on underwater apparatus, as these can release flammable gas which can be ignited by the arc.
- The fourth and final risk of underwater welding is decompression illness. The pressure and temperature of the air underwater can cause sudden decompression which, in turn, can cause nitrogen bubbles to form in the body, resulting in an illness known as “the bends.” In extreme cases, this can cause death. To prevent this illness, welders must use proper breathing apparatuses and practice safety procedures known as “stop and clamp.”
Ultimately, underwater welding can be an extremely hazardous job. However, with the proper safety and protective gear, welders can ensure that they are safe from all of the potential dangers. By following the proper safety measures and regulations, underwater welders can remain safe and avoid the risks associated with this unique and potentially dangerous form of welding.
