Performing underwater welding chores to keep a ship seaworthy is one of a commercial diver’s many responsibilities. These divers are up to the task no matter what the ocean’s circumstances are like! Underwater welding, as the name implies, is the act of welding while submerged in water. However, just because you’re good at welding on land doesn’t imply you’ll be equally adept at welding underwater. Here’s everything you need to know about underwater welding, from the process to the benefits.
How is underwater welding done?
Underwater welding, which was developed in the early 1930s but is still used today, keeps marine constructions in good condition. Welding is the use of high temperatures to unite two separate components. Welding underwater is an exciting technique, given the dangers of mixing electricity with water. And we’re all aware that water effectively puts out the fire, so how does this work?
The anode and cathode are charged positively, and the electrolyte is charged negatively in wet welding. In this technique, electrons can go from the cathode to the anode while positive ions pass via the electrolyte and the cathode, emitting the weldment where it’s wanted to. It is estimated that the heat produced by the massive motions of these particles is more than 5,000 degrees Fahrenheit.
Importance of underwater welding
Underwater welding is critical because it allows for ship, pipe, and rigging emergency repairs to be completed. The cost of employing an underwater welder is costly due to the danger to life and the high degree of skill necessary, but repairing the broken object underwater and reinstalling it later is typically cheaper than removing it from the water in the first place and having it repaired on dry land.
Risks and hazards of underwater welding
Electric shock is a danger when welds are submerged in water. To avoid this, the welding equipment must be marine-ready, appropriately insulated, and able to control the welding current. As well as the risks of decompression sickness due to the increased pressure of breathing gases, commercial divers must also think about other occupational safety hazards.
