How to Become an Underwater Welder

While a career as a commercial diver and underwater welder can be rewarding, it is not for everyone. The industry demands total commitment, long hours, extensive travel, a great attitude and superior work ethic.  If you're interested in becoming a commercial diver and underwater welder, then it's important that you be ready for a physically and mentally challenging career.

What You Will Need

If you believe becoming an underwater welder is right for you, these are the minimum requirements you will need to possess:

High school diploma or GED
Ability to swim
Mechanical aptitude
Commercial Diving Certification
AWS Certified Welding Training

Finding a School

A commercial diver certification requires significantly more training than a standard recreational SCUBA certification.  As a certified commercial diver, you are trained to work in industrial environments that frequently involve heavy construction and dangerous working conditions, including electrocution and pressure related injuries. 

Commercial divers receive the specialized training that allows them to work in a wide variety of environments, from inland dams and bridges to offshore pipelines and oil rigs.

In order to become a certified underwater welder, you will need formal underwater welding training from an accredited dive school and pass their program in accordance with the American Welding Society D3.6 standard. 

Choosing the right school is an important first step to getting certified. Learn more about what CDA Technical Institute offers its students here.


There are many costs associated with obtaining the required certifications to become a commercial diver.
