Have you ever operated a 10,000℉ flame underwater? Think it sounds hard? Persistence and focus are the keys to mastering this skill in Month 4.

In this course, you’ll learn the skills you need to both weld and burn underwater.

You’ll also get familiar with many new tools. Topside, you’ll use the electrode holder, chipping hammer, wire brush, 6010 electrodes, 7018 electrodes, oxy fuel rig which consists of a striker and a smith torch, as well as basic hand tools like grinders and wire wheels. Underwater, you’ll use twist lock electrode holders, chipping hammers, wire brushes, 7014 electrodes, and Broco exothermic torches.

Underwater welding creates a picture of a Shield Metal Arc welder working at depth. This is known as wet welding. The diver is wet, the repair is wet, the welding rod is wet. This is a very common method of underwater welding, and is what our training focuses on.

Another method of underwater welding is known as habitat welding, which is done underwater but in a sheltered environment void of water to keep the welding area dry. A dry habitat is installed where either the diver enters from the water into the dry habitat or where the habitat is enclosed so that the welding rod and welding environment stay dry. Both methods take skill and practice.

As part of the DIT curriculum, you’ll learn how both processes work and gain hands-on experience testing your underwater welding skills.

While underwater welding might sound intimidating, you’ll be trained to manage risks through safe practices and proven techniques. You’ll learn proper welding procedures in straight polarity, how to use a circuit interrupter (knife switch), where to place the work lead on your project, and how to use rubber-insulated hand protection. These steps make underwater welding both safe and effective.
