Underwater welding is an exciting and demanding profession.

It can also be financially rewarding.

Commercially-trained divers work underwater either in the water itself or in a dry container to perform their welding. 

Due to the amount of training required to enter this profession, underwater welding is considered a highly-specialized field. If you’re interested in becoming an underwater welder, you’ll need to seek out the proper training schools and programs.

Prerequisites To Becoming An Underwater Welder

To become an underwater welder, you have to meet the following prerequisites:

  • Have a High School diploma or a GED
  • Learn welding - the regular, dry-land version
  • Plus Circle
    Commercial diver’s certification from an approved certification/licensing program.
  • Plus Circle
    Get formal underwater welding instruction from an approved school or program that meets the American Welding Society requirements for certification.

How To Choose An Underwater Welding School

Underwater welding schools and training programs presume that you already know the basics of welding. Getting that knowledge should be your first step before you apply for an underwater program.

Training programs for welding can range from as few as 10-15 days to 7 months with additional courses available to teach skills required for the 4F overhead welding position and 5F positional pipe, plate, butt welds in all positions.  

Underwater Welding Schools

Once you’re ready to start learning underwater welding, you should be prepared for another several months of schooling. This includes time to get your commercial diving certification and underwater welding certification.

Some training programs include commercial diving certification; others require it separately as a prerequisite. Financial assistance is available for some programs. Another attractive feature can be job placement assistance, which is available again at some of the programs.

In order to choose the best school or training program for you, you will want to consider the following 7 factors:

1.  Location 

There are not very many schools and training programs in the U.S. devoted to underwater welding, thus you may have to travel and relocate temporarily to find the right training program.

2. Facilities

Given the nature of underwater welding, you’re not going to learn what you need to know sitting in a classroom.

You need a combination of classroom knowledge and real-world, hands-on training that can only be found outside of the classroom.

Underwater Welding In Pool

So you’ll want to look at the quality of the facilities. Does the school or program offer in-tank and physical training? How many hours are spent in the classroom and how many are spent in physical training?

3.  Cost

Make sure you know the overall cost of the program and what is included. Tuition costs can run anywhere from $5,000 to over $20,000. And those are only a part of the course or program costs.

Many programs require you to provide your own diving equipment and/or welding equipment and gear. That can include not just the tanks and face masks, but wetsuits, booties, overalls, and steel-toe work boots as well.

3.  Specific Skills that will be Taught & Certified

Most training programs or courses should teach underwater cutting & welding techniques, rigging, underwater repair or construction, use of underwater explosives and safety protocols involved in underwater welding.

They will also cover how to weld with specific equipment and power tools underwater.

Underwater Welding Classes

Many underwater welders obtain additional welding certifications in specific materials, positions, and water bodies such as lakes and rivers as opposed to just the ocean. Will you be taught how to weld within both a cofferdam and a hyperbaric chamber?

Underwater welders with additional skills such as cutting, rigging, installation, inspection, non-destructive testing, underwater photography and drafting are usually in high demand. So look into whether these are offered in the programs you look into.

4.  Certifications Provided

There is no one certificate that covers Welding and Diving. You will need a certificate in (1) Commercial Diving and (2) Underwater Welding.

Some underwater welding training programs include entry-level commercial diver training and certification as part of their program.

But if you choose a program that doesn’t offer commercial diver training, you’ll have to get that elsewhere before your underwater welding program.

Diploma For Welding

You want to be sure that the certificate that you will receive at the end of your training will be recognized and accepted by any employer in any type of underwater environment.  Make sure that the school or program is accredited by a reputable organization like the American Welding Society.

An international certification will allow you to work anywhere in the world in any type of underwater environment. This can provide great versatility and increase your opportunities for working in the oceans of the world.

If you plan to work primarily in inland locations such as lakes, rivers etc. then you will want to look into what type of local certifications (state or US) the program or course offers.

5.  Quality of the Instructors

You want the very best instruction you can find from individuals that have several years of real-world experience as commercial underwater welders and as instructors and have stayed current with their techniques.  How much experience do they have? Where did they receive their experience - lakes & rivers or the ocean? When was the last time they worked as an underwater welder in the field? Have they ever taught underwater welding courses before?

6.  Job Placement and Tuition Assistance

Due to the high cost of Underwater Welding Courses and Training, any reputable program should offer some type of financial assistance to help meet tuition costs.

Once you successfully complete the programs, many training schools will help place you with an employer so you can complete an apprenticeship. Hopefully that will lead to permanent employment with that company.

Some Of the Top Underwater Welding Schools in the US

You can start your research into specific schools and training programs on the Internet by going to the school or facility’s website.

Check out the information they provide about their program and what prerequisites they require for admission into their program or school. Once you have an initial overview of what they provide, develop a list of questions so you can call and get more detailed information.

Underwater Welding School

Don’t choose your school or training program without visiting their facilities and talking with staff and instructors face-to-face.

This step is very important - it will give you a feel for what it would be like to attend courses and training there and whether it’s the right learning environment for you.

Now let’s have a look at some of the top schools across the US.

About the Author Gregory

Hi, my name is Gregory! I have been welding practically all of my life and love it. As I have gotten older I have started to weld less and less, so in order to continue my love for welding I created this website. I like to write about my experiences and help you all become welders. I hope that you enjoy the site!
