Welding Underwater

If you read our blog posts, you know we discuss how many types of welding jobs there are available and how many industries rely on these useful skills to operate. This week, we’re going to take a close look at welding that takes place below sea level. If you’re unfamiliar with underwater welding, it may be pretty unbelievable to think that this type of work is possible but get ready because we have some interesting information to share.


The first distinction to make in this type of work is between dry welding and wet welding. In dry welding, welders are indeed underwater but work in a habitat that is water-free. These habitats are called hyperbaric chambers and they are cleared of water and pressurized to the correct depth. You may have guessed it, but wet welding involves welding directly in water. How is this possible? It’s usually not a good idea to mix electricity and water but this profession has been around since the 1930s and although it’s dangerous, people continue to work in the field. The key lies in the layer of gaseous bubbles which protects the weld and separates it from the surrounding water. These bubbles are generated by the external coating on the electrode so making sure you have the right equipment in working order is absolutely vital.


If you’re intrigued by the idea of branching out to underwater welding, it’s important to first do your research. This career requires a great deal of training and certification. If you already have welding skills, you’ve got a leg up but there’s more work ahead. Getting diving certifications and acquiring specialized skills for this job will be mandatory. Beyond that, there are some risks to take into account, such as the danger of electric shock, drowning, and hypothermia, to name a few. But if you get beyond that, you reap the benefits of an exciting and well-paying career which is in high demand!
