Underwater welding, sometimes called wet welding, is a well-suited process for many applications. The process is used with a variety of materials, including steel, aluminum and stainless steel, and anywhere that welding is required underwater or in similar wet environments.
Underwater welders are highly-skilled in this specialized type of welding. Welders use electrode, flux and filler materials that must all work together to provide a quality weld joint. Each weld must meet not only welding code standards, but also rigorous safety standards.
Underwater welders must be highly trained and certified in proper welding techniques, as well as in the physics of pressure, flow and other marine engineering concept. Dive operations must be performed using recognized industry and government standards. Welding fleets must be properly maintained, inspected, and equipped with the necessary breathing apparatus and pressure suits.
Underwater welders benefit from significant technological advancements that have increased safety and improved the efficiency of the job. Specialized tools, such as remotely operated vehicles (ROVs), allow welders to inspect welds from a safe distance and to complete repairs in a fraction of the time it takes to do a traditional weld.
New welding processes, such as automated welding, provide the same quality weld with less manual labor and a fraction of the time it takes to manually weld. Automated welding systems, such as those used in the aerospace industry, can provide better welds by automating process parameters. Further, robot welding systems that combine advanced sensors, electronics and computer software allow welds to be completed with less effort and greater accuracy than traditional welders.
Underwater welding can be a dangerous job, and safety must take priority over all other considerations. PPE and safety equipment must be worn by welders and staff at all times, and proper welding practices must be adhered to, including all applicable codes.
Training and certifications can be obtained from a variety of sources, such as industry organizations, trade schools and educational institutes. Before taking a welding job, welders should research the welding codes and safety standards that apply to the specific job they are performing.
Underwater welders work in some of the most challenging environments, and with the potential for danger around virtually every corner, safety must be the foremost consideration. With advancements in technology and safety regulations, welders can better ensure their safety and the safety of those around them through proper safety training and preparation.
