You first need to possess a standard certification as a welder. After that, you can go on to obtain your commercial diver's license before completing your specialized certification training at a reputable underwater welding school.
Follow the below standard certification and training to become a underwater welder.
# Completing Your Welding Certification :-
## Receive your high school diploma or GED :- The first step along the path to becoming an underwater welder is to complete your base level of education. Most employers will expect to see at least a high school diploma, but you can also get your GED if you're returning to school after an absence
## Get certified as a topside welder :- Seek formal training in one of several individualized welding processes through an accredited welding school. If you live in the U.S., you also have the option of completing the Certified Welder program offered by the American Welding Society (AWS). You'll be awarded your certification after passing both a written and hands-on practical exam
## Gain a few years of experience working as a topside welder. While it's technically possible to get a job as an underwater welder right out of the gate, having 2 or more years of direct experience will greatly improve your chances. This will prove to employers that you're proficient in welding techniques and safety procedures on dry land, and are ready to apply them in an aquatic setting.
# Receiving the Necessary Dive Training :-
## 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
1. 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.
2. If you exhibit symptoms of asthma, claustrophobia, severe motion sickness, collapsed lung, cardiac arrhythmia, or congestive heart failure, you may be denied certification permanently.
## 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
## 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.
## 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
## 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
