Careers in Underwater Welding

Commercial diving encompasses many different occupations in various locations around the world. When you think of diving, most people just assume deep ocean waters, but that’s not always the case. In this field, there are plenty of jobs to be had onshore and offshore, dealing with a variety of situations, equipment, and skills. Underwater welding is just one aspect of commercial diving, and as a commercial diver, you’ll be expected to do more than just weld. These are some of the opportunities awaiting you once you become commercial diving certified and wet welding certified.

Inland Diving

Lakes, rivers, dams, and more still need divers for many different jobs and situations. You’ll be dealing with high currents and low visibility, and you’ll often be asked to travel regularly. Some of the jobs you may be tasked with include pier and pile repair or installation, underwater construction, building and repair of dams and bridges, and even husbandry of ships.

Offshore Diving

This is what many think of when they hear about commercial diving. Offshore work is done in the open ocean off of ships and platforms across the world. It can include a variety of different tasks such as repairing oil rigs and pipelines, building oil structures, salvaging shipwrecks and old oil structures, and various types of subsea construction. This work is very difficult and dangerous, and as such, it compensates very well. You may be asked to work around the world such as the Gulf of Mexico, the North Sea, West Africa, and many other places. Because of seasonal changes that make the waters more dangerous during parts of the year, offshore commercial divers often work for only part of the year, usually April to November.

Dangers of Underwater Welding

Commercial diving can be a very lucrative career, but part of the reason for the high pay is the high risk that commercial divers are taking on. According to one study, underwater welding is the most dangerous occupation with workers experiencing the highest fatality rate of any occupation. Underwater welder’s fatalities aren’t tracked as an individual group, but within the industry it’s estimated to have a 15% fatality rate, making it 75 times more dangerous than some of the most dangerous occupations in America.

Many risks present themselves with underwater welding. Divers have to be concerned with electric shock and must wear special equipment to avoid it, but it only mitigates the risk and doesn’t remove it. Explosions are also a possibility because of gasses used in the welding process. Decompression sickness is also a concern, even when all precautions are taken. Sometimes mother nature herself is the culprit, in the form of dangerous marine wildlife, though this is less likely than other dangers. Of course, anytime you’re fully submerged in the depths of great bodies of water, drowning is a very real possibility, whether caused by diver error or equipment malfunction.

Commercial diving and underwater welding specifically can be a very rewarding and lucrative career, albeit a dangerous one. For skilled workers, major companies are willing to pay very well, and it’s a growing industry with plenty of opportunities for employment. With so much at risk, it’s important that you get the best education possible and arm yourself with all the knowledge and certifications that you can. The underwater welding schools listed in this article are the best of the best in the U.S. Any of them is a great choice to learn the skills you need for a safe and long-lasting career in commercial diving and underwater welding. With choices available across the country, you shouldn’t have to travel too far, though the best options may require relocating for a time. Of course, you’ll most likely need to relocate for your career once you finish schooling, so you might as well get used to it now.
