What is an Underwater Welder?

The following job responsibilities are common for individuals in underwater welder roles:

  • Perform hyperbaric welding while wearing commercial diving equipment
  • Repair metal components and equipment contained in fresh and salt bodies of water
  • Perform emergency repairs of bridges, dams, oil platforms, and other submerged structures

A Day in the Life

An underwater welder is responsible for hyperbaric welding and other related tasks that can be used in a wide range of applications, including ship repair, oil platform construction, and more. Because most of these tasks are completed only when needed, many commercial divers choose to include welding as one of their abilities rather than considering underwater welding as a primary career. Those underwater welders that are employed full-time are commonly hired by marine construction firms.

While ocean-based work may be more common, underwater welders may also find employment in inland areas, such as at a dam or a bridge over a river. However, most underwater welders will choose to live near the ocean to maximize their chances of finding work. Because of the specialized training needed and the fact that underwater welding can be utilized in many marine industries, a person may be engaged in very different activities depending on their employer.

Tasks associated with underwater welding like urgent rigging needs and emergency repairs can appear quickly, meaning that you’ll need to have an open schedule and be able to react quickly when the need for an underwater welder appears. Some underwater welders may have normal employment contracts, but many are also employed on a freelance or as-needed basis. As such, there are fewer standard day-to-day tasks, and most jobs will require using underwater welding knowledge on a case-by-case basis.

Typical Work Schedule

There really is no typical work schedule for underwater welders. Some underwater welders live on oil rigs and may be required to work overtime, any time of the day, any day of the week, and many days in a row without time off. Underwater welders are also commonly on-call to handle emergencies.

Typical Employers

The largest number of underwater welders are employed by oil companies to perform maintenance on offshore oil rigs. However, other employers of underwater welders include—but are not limited to—research facilities, federal, state, and local governments, and nuclear power plants.

How To Become an Underwater Welder

To obtain an underwater welding position, there are a number of requirements. While an associate’s or bachelor’s degree are not needed, you will need to have completed training for commercial diver certification. This process to become a certified underwater welder can differ between countries, but equivalencies are maintained by the International Diving Schools Association and are applied to a 4-level system that ranges from commercial scuba certification at the lowest level to closed bell diving at the highest.

In addition to commercial diving certification, a prospective underwater welder will also need to have training and certification in welding from the American Welding Society or an accredited institution. As with diving certification, you’ll find different levels of training on offer, with underwater welding being identified by the AWS 3.6 label. All programs with AWS 3.6 training will provide the requisite certification to be hired as an underwater welder.

Apart from the commercial diving and welding certification requirements, the knowledge needed for a career in underwater welding includes the ability to swim proficiently as well as a generally good physical condition as the job can be strenuous. Depending on the specific company, you may be required to have a doctor complete a physical exam before being hired. Underwater welders must also maintain certified status by passing proficiency tests on a regular basis.
