Introduction

Are you fascinated by welding and the ocean? Underwater welding combines the precision of metalwork with the thrill of diving. If you’re wondering how to become an underwater welder, this guide walks you through the steps, qualifications, training, and certifications required to pursue a successful underwater welding career.

What Is Underwater Welding?

Underwater welding (also known as hyperbaric welding) is a specialized skill where welding is performed in wet or dry conditions under water. It’s typically used in offshore oil rigs, ship maintenance, bridge construction, and subsea pipelines. This demanding career blends two professions: commercial diving and welding.

Step 1: Meet the Basic Requirements

To start your journey, you need to meet a few basic criteria:

Age: At least 18 years old

Education: High school diploma or GED

Fitness: Good physical and mental health

Swimming ability: Must be comfortable in deep water

Many employers also require a clean background check and drug screening.

Step 2: Get Certified in Welding

Before diving in—literally—you need solid experience in topside welding. Enroll in a welding training program at a trade school or community college. Focus on certifications like:

Shielded Metal Arc Welding (SMAW)

Flux-Cored Arc Welding (FCAW)

Gas Tungsten Arc Welding (GTAW)

Obtaining an American Welding Society (AWS) certification can improve your credibility and job prospects.

Step 3: Complete Commercial Diving Training

Once you’re a certified welder, the next step is enrolling in a commercial diving school. These programs typically last 5 to 12 months and cover:

Diving physics and physiology

Underwater tools and cutting

Decompression procedures

Safety regulations

Hands-on underwater welding practice

Ensure the program is accredited by the Association of Commercial Diving Educators (ACDE) or Divers Institute of Technology (DIT).

Step 4: Obtain Underwater Welding Certification

After completing your diving program, you’ll need an underwater welding certification. The American Welding Society (AWS) offers the Certified Welding Inspector – Underwater qualification, while the International Marine Contractors Association (IMCA) also provides relevant credentials.

Some certifications include a practical test in a hyperbaric chamber or dive tank.

Step 5: Gain Experience and Build Your Career

Start with an entry-level job as a commercial diver, such as:

Offshore oil rig maintenance

Subsea construction

Ship and barge repair

Pipeline inspections

As you gain experience, you’ll move into higher-paying roles. Continue renewing your diving and welding certifications to stay compliant and competitive.

How Much Do Underwater Welders Make?

Underwater welder salaries vary widely depending on location, experience, and the type of job. On average:

Entry-level: $40,000 – $60,000 per year

Experienced professionals: $75,000 – $150,000+ per year

Hazard pay and offshore bonuses can significantly increase earnings

Is Underwater Welding Dangerous?

Yes, this job carries inherent risks such as:

Electric shock

Decompression sickness

Drowning

Explosions in enclosed spaces

That’s why rigorous safety training and following protocols are essential.

Final Thoughts

Becoming an underwater welder is not easy, but for those with a passion for both welding and the sea, it’s an incredibly rewarding and high-paying career. By following these steps—getting certified, training as a commercial diver, and obtaining underwater welding credentials—you’ll be on your way to a successful underwater welding career.
