How to Become an Underwater Welder


Hyperbaric welding is a gratifying and exhilarating career option for individuals who have skills in welding and who are comfortable in underwater environments. The unique challenges of the career often draw trained and talented professionals into the field. There are a number of considerations to research when considering a career in this field, including everything from job responsibilities and career outlook to the skills and education that are helpful for preparing to become an underwater welder.


Required Skills and Qualities


Special talent, skills, and interests are a must in becoming a professional underwater welder. To begin, professionals in this field will need to have a minimum of a high school diploma or a GED in order to enter into the educational programs to complete the required professional training. In addition to this basic education requirement, professionals in the field often benefit from having both mechanical and mathematical aptitudes, strong work ethic, willingness to travel, ability to work long hours, and enjoyment of physical work. Underwater welders must also be able to swim, and the stronger swimming skills a candidate has, the easier the tasks associated with the position can be.

Job Description and Responsibilities

Underwater welders utilize specialized equipment to perform a number of surveying and welding tasks in underwater work environments. Often, the work is performed in hyberbaric chambers with electric arc welding rods. The chamber provides mechanical shielding from the water. In some cases, however, welding is completed with no shielding from water.

In addition to welding, underwater welders often perform a number of other tasks. Some of these responsibilities include surveying or construction work. Some common tasks an underwater welder will complete include clamping pipes, setting brackets, setting risers, putting in pipelines, ship hull repair, underwater salvage, and code surveying.

Choosing the Right Education, Certifications, and Training


At a minimum, underwater welders are required to hold a Commercial Diving Certification from an accredited institution or program and a Certified Welding Certification from the American Welding Society. Typically, qualified welders with the appropriate certifications and education will continue the process to enter the profession by completing a minimum two-year apprenticeship.

In some cases, a schools education program can help future professionals work toward earning both of the required certifications.
