Taking the Plunge: A Guide to Starting an Underwater Welding Career
Over the years, a number of people have expressed an interest in careers in underwater welding, but were unsure how to get started. Welders, students, divers, and other interested men and women have contacted the American Welding Society (AWS) for guidance. In order to help those prospective underwater welder-divers, the D3B Subcommittee on Underwater Welding has provided answers for some commonly asked questions.
The skills suggested for entering the field of underwater welding can best be defined by the following typical description of a welder-diver from the AWS D3.6 Standard. "Welder-diver: A certified welder who is also a commercial diver, capable of performing tasks associated with commercial subsea work, weld setup and preparation, and who has the ability to weld in accordance with the AWS D3.6." By description, an experienced welder - diver must possess: commercial diving skills (i. e., be familiar with the use of specialized commercial diving equipment, have an understanding of diving physiology, diving safety, rigging, the underwater environment, communication, etc.); weld setup and preparation skills (i. e., the ability to perform tasks typically assigned to a fitter or rigger, such as materials alignment and materials preparation including beveling, stripping of concrete, fitting a steel patch or repair plate, etc.,); and the ability to certify to a required underwater weld procedure.
The majority of work performed by an average welder-diver does not involve the welding operation itself, but rather executing the tasks that lead up to and follow the actual welding activities. Except under special circumstances, a welder-diver in most cases must posses both certified welder skills and commercial diving skills. It is suggested that if you have no prior commercial diving experience you should attend one of the recognized commercial diving schools. The candidate may be required to pass a diving physical prior to school acceptance and in some cases a written exam. It is
suggested that a dive physical be taken regardless, to avoid going through the expense of training only to later find you have a disability that prevents your entering the profession. Once that basic commercial diver training is completed, it is common practice to apply for employment at one of many commercial diving companies that offer underwater welding as a service. An interview with the company of your choice is recommended to express your career goals in underwater welding and past welding experience. Expect to begin your career as a diver tender (apprentice diver) initially. As a diver tender you will gain valuable practical experience while learning the trade.
The welding processes, classes of weld and qualification tests associated with underwater welding are described in ANSI/AWS D3.6. We recommend the specification as a reference for weld procedure and welder qualification. It is also a good source of other helpful information. If you are already certified as a "commercial diver" and work for a company that offers underwater welding services, it is recommended that you communicate to your company your career objectives and ask what welder skills they are looking for. If you are certified as a "scuba diver", it is suggested that you attend a commercial diving school. Sport dive training does not include the safe use of commercial diving equipment, offshore commercial work environment/safety, and other education. Underwater welding is a skill you also have to master once you obtain the basic commercial diving skills required.
There is no age restriction on commercial welder-divers. There are, however, physical requirements. It is recommended and generally required that all commercial divers pass an annual dive physical. The commercial diving profession is physical demanding. It is rare to see an active commercial welder-diver over the age of 50.
We know some welder-divers earn $15,000 per year while others earn in excess of $100,000. Because the majority of welder-divers are paid on a project-by-project basis, salaries are subject to the same variables as work availability. In addition, other factors such as depth, dive method and diving environment affect pay rates. The company with whom you gain employment should be able to tell you the salary range you can expect to earn.
Ideally, a diving contractor would like its welder-divers to be "a jack of all trades and a master of them all!" Practically speaking, possessing the skills that are common to underwater welding operations, in addition to welding and diving, are recommended. Primarily these skills are: underwater cutting (oxyfuel, abrasive water jet, mechanical cutting equipment, etc.); fitting and rigging; inspection and nondestructive testing (visual, magnetic particle, ultrasonics, radiography, eddy current, etc.); drafting; and underwater photography (still photo and video). The more skills the welder - diver maintains the more valuable he becomes in meeting project qualification requirements. The most desirable underwater welder-divers are those who are qualified to: assist the diving contractor in pre-job planning (e. g., having the ability to photograph/video, draft and report on work requirements prior to the actual underwater welding operation); cut, clean, rig, install, and fit up the sections they will weld; and work with personnel responsible for inspecting the completed welds. Formal training is recommended for whatever skills you wish to qualify for. Maintaining the qualifications you obtain is just as important as receiving them as there has been many a job lost to a welder-diver who has let his certification lapse.
There are a number of career opportunities for experienced welder - divers. Many go on to become engineers, instructors, and diving operations supervisors, fill management positions, qualify as AWS Certified Welding Inspectors (CWI), and serve as consultants for underwater welding operations and other related fields. Ideally, a career as a welder-diver should serve as a stepping stone to other opportunities for those who choose the profession. Industry has and will continue to demand higher quality standards for underwater welds and more certification of underwater welding systems and personnel.
