Underwater welding positions are typically categorized as wet welding or dry welding. Different positions are required based on the job’s depth, location, and structure.
Underwater welding, a highly specialized field, combines diving skills with welding expertise to repair and install structures under the sea. These professionals face unique challenges, such as varying water pressures and the need for diving proficiency. Two primary methods, wet welding and hyperbaric (dry) welding, dictate the positions and techniques used.
Wet welding is directly performed in the water, with the diver exposed to the elements, while dry welding takes place inside a specially constructed positive pressure enclosure submerged in the environment. Divers must be adept at both to ensure the integrity and strength of the welds. This skill set requires rigorous training, as welders must be able to operate in a range of underwater positions to access and repair complex marine structures. Understanding the nuances of each position is crucial for the success and safety of underwater welding projects.
