Things to Consider When Choosing an Underwater Welding School

There are various underwater welding schools to choose from. They offer different training certifications and facilities.

Your choice depends on your underwater welding career plans. You should also consider tuition costs, program lengths, financial aid, location, and job placement assistance.

Cost of Attendance

Underwater welding training courses are expensive. Average tuition worldwide is about $15,000, while approximate education in the US costs around $17,500.

Several factors affect the cost of the training. They vary from the school and include a degree of specialization, certification, and career opportunities.

In most cases, besides tuition, you will have to pay for the equipment, books, housing, and other living expenses.

Tuition Assistance and Financial Aid

Since programs can be pretty expensive, most of the interested students cant afford underwater welding schools. That’s why it is essential to choose a training school that offers Federal Assistance Programs and other financial assistance to their students.

Before you make your choice, you should contact the finance office and find out if they can make it easier for you. Luckily we included the helpful information in the article to help you make the right choice.

School Location

School location is one of the essential things you need to consider when making a choice. If you live far from the institute, you’ll need to arrange housing or pay extra funds for living on campus.

Diving training can be exhausting, so traveling to your school every day can be challenging. In addition, some of the schools are located near the parts where actual underwater welding jobs are being done. That way, you have a real-world experience while studying.

Program Length

Keep in mind that underwater welding programs are much shorter than other occupations. For example, most commercial diving courses in the US are 25.5 weeks long, while some can be as long as 35 weeks. However, extensive training can even last 88 weeks.

You should fit the program length to your need. Keep in mind that course length determines how in-depth your training as an underwater welder can be.

Job Placement Assistance

Commercial diver salary is one of the essential things people consider before choosing the best underwater welding schools. To get there, you want to select a school that will help you find employment and prove your skills.

Some of the listed best underwater welding schools will help you start as soon as you complete your training. Starting employment right after graduating from an underwater welding school will help you practice and learn new hands-on training and skills every day. In addition, you will earn an excellent underwater welding salary.

Careers in Underwater Welding

When people talk about diving, the first thing they assume is deep ocean water. However, commercial diving is being done in various locations around the world, either inland or offshore.

Keep in mind there are plenty of jobs, onshore and offshore, and prepare students for different risks such as electric shock, differential pressure, or decompression sickness.

Inland Diving

Inland underwater welding includes many different jobs and situations in the lakes, rivers, dams, and more. Divers are dealing with low visibility and high currents. In addition, they travel a lot.

Most of the jobs include pier and pile repair or installation, underwater construction, building and repairing a dam, or even ships.

Offshore Diving

Offshore diving is the first thing people think when talking about underwater welding.

Commercial divers work in the open ocean, off ships, and on platforms across the world.

You will be charged with repairing oil rigs, building oil structures, salvaging shipwrecks, and other types of subsea construction.

image of the offshore oil platform in the ocean

Keep in mind that offshore diving is difficult and dangerous. In addition, underwater welding pays a lot. Underwater welders work worldwide, such as in the Gulf of Mexico, the North Sea, and many other places.

However, job opportunities are limited to a season, usually from April to November. The reason is harsh environmental conditions, such as strong currents and possibly dangerous waters.


Commercial diving, including underwater welding, is as rewarding as it is a risky career. Experienced and skilled workers are always wanted, and major companies pay well.

To get to a place where you can choose your job, you first need to get a proper education. To reduce a risk that is usually linked to the profession, you’ll need to select one of the best underwater welding schools.

When making a choice, you need to think about several things. The ones that stand out are the location, costs, job placement, and tuition assistance.
