Here’s a list of best US underwater welding schools:

3 Differences Between Underwater Welding Courses

The differences in commercial diving courses comes down to several characteristics.

Here’s the top three:

  1. Cost
  2. Program Length
  3. Location

Analyze these features closely when researching underwater welding schools.

Your future as a welder-diver depends on it.

Underwater Welding School Cost: Value Based on School Facilities & Reputation

The underwater welding school cost comes to an average of $14,901. This rate combines tuition from 16 underwater welding schools around the world. The most expensive three schools cost $21,800 – $23,400, while the least costly range from $2,800 – $4,755.

If you only only factor in US underwater welding schools, you’ll spend an average of $17,475.

I took out the rates of three schools’ programs whose courses are more specialized:

  • ABJ Welding
  • Hydroweld
  • XLT Institute of Welding

As you can see, training to become an underwater welder isn’t cheap.

You will purchase all your own equipment, books and pay for housing and tuition.

Plus food, travel and other living expenses.

Still, think of it this way:

Commercial diving schools fall into the “trade school” academic category. These types of schools average around $30,000 – $35,000.

So in comparison, you’re getting a steal.

It all depends on what you consider valuable in the program you attend.

Program Lengths: How Long You Have to Go to School to be an Underwater Welder

Programs range in length as much as cost. On average, commercial diving students will train for 25.5 weeks. The longest three courses range from 35 – 88 weeks, while the shortest three only take 6 – 12 weeks.

Again, these numbers exclude the three specialized underwater welding schools.

Now you know the basics, let’s take a look at each school by location.

29 thoughts on “Top 9 US Underwater Welding Schools with Certified Results”

  1. I love underwater welding and i will like to do the course at IDI but my problm is the tuition fees is much for me, don’t have upto that amount of money.

  2. So I’m looking at CDA, honestly just because of the housing and meal plans. I too was torn between CDA and DIT. Are the class days so long at CDA that i wouldn’t be able to get a small petty job in the area just to keep my child support being paid? That’s really my last issue with enrolling. The offshore survival training looks fun too!!

    • Hey Gary!

      I would check with CDATI directly to see what you can work out with them in terms of program hours. Most schools have a little flexibility, it’s just a matter of talking through it with them.

  3. Hello….in 2010 I took a 9 month Journeyman Pipe Welding class which covered MIG, TIG, Stick, and Fluxcore. I was certified in all aspects. I have worked as a welder since then so I’ve gained a lot of on the job experience. Ive mainly performed MIG and Fluxcore welding since school and consider myself a pretty descent welder. I am thinking of taking my welding career into the realm of underwater welding. What would you suggest in terms of schooling considering I don’t need a lot of welding instruction. I’m not saying I know everything in regards to welding, but my focus would be more on the commercial diving aspect with more of a “refresher” if you will on the welding side of things.

  4. Im over thinking myself into confusion… its hard for me to deside because i dont mind the cost, program length, nor location of the school. So my question would be which training facility offers more certifications?

    • Hey Donte, it’s less about the quantity of certs than the quality. You want to get certifications that meet your needs (working inland versus offshore, or as a DMT or something else). Determine which direction you want to take your commercial diving career, than research the schools to see which have the certs to line up with that.

  5. Matt, I’m close to NUPI and have family in Jacksonville for CDA. In your opinion which school would be better?

    • I guess my question is if money and location wasn’t an issue, which school has the best training/facilities for someone looking to start a new career?

      • Hey Ryan, there’s honestly not a single “best” dive school out there, because each school has pros and cons that may be weighted differently dependent on the person.

        I would begin by:
        1. Talking to each of the schools (list out the questions you want to ask each for apples to apples comparison).
        2. Learn about some of the instructors (hopefully on the website – see if they have previous diving experience and if so how much)
        3. Weigh in other factors (school cost, facilities, program length, etc)

        I hope this gives you a good start. The difficult of this decision is the main reason I wrote my underwater welding guide, because it gives you a complete perspective on what’s involved in training for stronger preparation.


        If you’re interested, contact me via my email (matt@waterwelders.com)

  6. Any thoughts on NUPI? I’m considering it but I’m not sure if there is good opportunities around california for jobs after the course is done.

    • Hey Cameron, NUPI has a strong program for commercial diving. The key is to choose schools with a similar program and determine the pros and cons of each (length, certifications, etc). Then you can narrow down your choice.

  7. Hi! Obsessed with this website and has really helped me understand the industry thoroughly. I did want some advice however, I plan to make this a career for life. I’m torn between DIT and CDA. The main difference is price (5,000 dollar difference) and one particular certification-offshore survival. How vital is this certification? How important is it to have a fork lift operator cert? Thanks (:

      • I did read the article and it did help me bring it down to these two schools. DIT does offer a dive medic course that is two weeks long. Is that equivalent to offshore survival? Thanks again for helping me out. I’m just going to follow the work and want to go to a school that gives me a well rounded education and multiple certifications. They are identical in certifications except for the two CDA offers ( AWS WELD and the offshore survival) but I’m just not sure how important it is. Dive medic certificate i feel would have more pull when looking for a job as opposed to “oh I took an offshore survival class). thoughts?

        thanks again!

      • Natalia, because you’ve been able to narrow down your choices to these 2 schools, I would focus on other attributes rather than certification since you’ve found them to be quite similar. I would compare cost, learning environment (facilities, classrooms), instructor experience (as much as you can gather).

  8. Bwhahahahahaha Hey Matt, since when did you become an advocate for Professional divers? Go away worm………………There is no work, you wont learn dick and you will get ripped off!

    • Hey Jasper, yes – it’s absolutely possible depending on the school’s international student policy. Please contact the schools directly to determine if you can apply and attend!

  9. I am interested in CDA Tech, but their tuition is really expensive. How do you justify spending that much for training? And what are some ways to figure out which school is best?

    • CDA Technical is a strong school with a great training program. In comparison to some schools it may be considered expensive, but they do offer on-campus housing and meals (value that most schools don’t offer).

      • Thanks for these answers Matt! I’ll definitely check out that link. Part of my problem is that I really don’t know my goals in 1 year, much less 5 years down the road. So how do I make a decision on the school without knowing that?

      • I don’t have an easy answer for you, though I assure you many people are in the same boat (pun intended). I would spend another month doing your research to determine if this career is right for you:

        Talk with other underwater welders on forums and Facebook groups.
        Reach out to a few maritime companies and ask what it takes to get hired with them (don’t be shy, in my experience they love speaking with people about what they do).
        If you get a chance, talk to a few graduates and instructors of schools you’re interested in.

        This should put you on the right track and help you know how passionate you are for underwater welding. If you’re unsure, reach out to me again 🙂
