Commercial Diver Training in San Diego, California

The commercial diving and underwater welding school require you to develop a high level of knowledge in the areas of Diving Physics, Hyperbaric Medicine, Rigging Fundamentals, and more. National University Polytechnic Institute offers our students the opportunity to learn in the classroom, train in our on-campus 40,000 gallon dive tank, and demonstrate their ability during pierside operations on the Coronado Bay. What an amazing feeling to step off the pier in front of the World Famous Coronado Bridge. Truly a once in a lifetime opportunity. We only run four classes per year, each being 8-months long, and spaces fill up quickly.

Commercial Diving and Underwater Welding School

Along with the premium location of the campus, students will experience training in beautiful areas like Coronado Bay. Some inland diving companies are located nearby as well.

Safety is emphasized at the beginning and end of training. Underwater welders work inside of an enormous tank containing 44,000 gallons of water. The underwater welding school also includes a mixture of topside and marine skills: One day, you’ll learn how to operate a forklift, the next, you’ll be inside of a decompression chamber.

Students will focus on underwater welding and burning as part of their training. They’ll learn basic theory of stick welding in wet and dry environments and weld according to AWS 3.6 coding specifications in multiple positions.

Learning Underwater Welding at NUPI

The course takes place during the last 4 weeks of the commercial diving school and is intended to train professional divers up to the standard required to pass a Welder Performance Qualification (WPQ) to AWS D3.6 Code for Underwater Welding of class ‘B’ welds.

Upon completion, students will receive: Certification of Completion in Underwater Welding to the standards set by the American Welding Society.
