Get certified as a topside welder. Seek formal training in one of several individualized welding processes through an accredited welding school.

Receiving the Necessary Dive Training

1
Take and pass a preliminary dive physical. In most cases, you can sign up for a physical with the same institution offering the commercial diver certification you're seeking. Along with a head-to-toe examination, you'll also be tested on your swimming abilities and cardiovascular conditioning.^{[7]

- Having drugs, alcohol, or an infectious illness in your system can be enough to temporarily disqualify you from receiving a commercial diver certification. In this case, you'll need to retake the physical once you're clear of the offending substance.
- If you exhibit symptoms of asthma, claustrophobia, severe motion sickness, collapsed lung, cardiac arrhythmia, or congestive heart failure, you may be denied certification permanently.^{[8]

- It's recommended that you submit to a dive physical before going any further, even if the dive school you plan on attending doesn't require one. You may discover that you have some type of limitation that won't allow you to pursue a career as an underwater welder.
2
Become a certified commercial diver. Enroll in a commercial diving academy in your state or territory and work your way through their training program. The duration of these programs vary, but most are set up to be finished in 5-6 months, or around 900 training hours. Upon completing the program, you'll be receive a valid and industry-recognized commercial diver certification.^{[9]

- Some commercial diving academies make it mandatory for applicants to pass a written entrance exam and a dive physical before they're accepted into a specific program.
3
Attend an underwater welding school. This is where you'll bring your 2 newly-acquired skills, welding and commercial diving, together. The course content and length of underwater welding programs can vary greatly, but most consist of both traditional study and hands-on training in wet welding skills, and may range from 6 months to 2 years.
- In addition to classroom curriculum, most programs will require you to clock a certain number of dive hours (usually 20-50) in order to be approved for certification.^{[10]

Apply for a dive tender position to continue your training on the job. Most underwater welders don't start off in high-profile positions. Instead, they begin as “dive tenders,” apprentices that provide assistance to experienced professionals during dives. Submit your resume, complete with your new credentials, to the company of your choice to add your name to the fold of potential hires.^{[12]

Continue improving your skills to advance in your field. The tools you'll need to excel as an underwater welder will depend on the company employing you, the nature of the work they do, and the specific industry regulations in place in your area. Some of the most important skills to possess include cutting, rigging, and fitting metal components, drafting design plans and standards, and testing and inspecting finished projects.^{[14]
