This prevents electric shock, which is the biggest threat to their safety. Special waterproof equipment is also used for all underwater welding jobs.
Preventing Electric Shock
Underwater welding is a risky job that requires immense skills to keep the welder safe. The electric shock poses the greatest threat to underwater welders, and as such, they have to take necessary precautions to avoid it.
It is essential to note that electric current will always take the path of least resistance, and since water is a conductor of electricity, one would expect electric current to pass through the welder’s body. However, this is not usually the case as the following H3 headings explain how underwater welders prevent electric shock.
Isolated Circuit
To prevent electric shock, underwater welders use a method called a fully insulated electrode. Essentially, this electrode is made from a protective covering and then submerged into the water to make the circuit.
Only the cover is in contact with the water making the system isolated. This method is crucial as it helps reduce risks of electric shock or electrocution from stray currents from other sources.
Thick Gaseous Bubble Shield Another method used to prevent electric shock in underwater welding is the thick gaseous bubble shield. A layer of bubbles surrounding the welding area reduces the electricity’s conductivity by as much as ten times, as the bubbles protect the electrode and weld.
This method not only protects the welder but is also useful in reducing the corrosion of the electrode from saltwater and other oxidizing compounds.
In conclusion, underwater welding is a hazardous job that requires expert knowledge to prevent electric shock and other severe injuries. A fully insulated electrode and a thick gaseous bubble shield are two methods used to safeguard the welder in the process. These safety measures ensure that underwater welding is completed safely and successfully.
How Does Underwater Welding Work?
Underwater welders don’t get electrocuted because they use a thick layer of gaseous bubbles externally around the electrode, covering the weld and shielding the electricity from water, corrosive gases, and other oxidizing compounds. This prevents current from passing through the welder’s body.
As underwater welding continues to gain popularity in various industries, one question remains on the minds of many people – how does underwater welding work? Underwater welding is a challenging task, but thanks to technological advancements, it is now easier to weld underwater without risking the life of the underwater welders.
In this article, we will take a closer look at how underwater welding works, with a particular focus on electrodes and workpieces, isolated circuits, and bubble shielding.
Electrodes And Workpiece
For underwater welding to work, a welder must have two crucial components – an electrode and a workpiece. The electrode, which is a metallic rod, produces an electric arc that heats the metal workpiece to its melting point. The electric arc, which conducts electricity, is created when the electrode is brought close to the workpiece.
Isolated Circuit
Since water is an excellent conductor of electricity, underwater welding can be dangerous. To prevent electrocution, welders create an isolated circuit that ensures that electric current flows only between the electrode and the workpiece. The circuit is isolated by attaching a cable from the generator to the welding machine and then to the welding electrode.
Bubble Shielding
Another vital aspect of underwater welding is bubble shielding. To prevent underwater welders from being electrocuted, a thick layer of gaseous bubbles is created externally around the electrode, covering the weld, and shielding the electricity from water, corrosive gases, and other oxidizing compounds.
The bubble shield is created by releasing a supply of compressed gas through small holes in the electrode holder to surround the electrode.
In conclusion, by using an electrode and a workpiece, creating an isolated circuit, and bubble shielding, underwater welding has become a safer and more effective method of welding in various industries.
By adhering to these techniques, underwater welders can work efficiently and confidently without risking their lives.
