Plasma cutting produces fumes and smoke. While the fumes and smoke are contained to a large extent by cutting below water, a large amount of it remains in the atmosphere above water. This makes it important to consider the volume of cutting and the level of water at which the plasma will be operating. Generally, water at a depth of about 1/2" or more is sufficient to capture 98% of the smoke and fumes.
The process of underwater plasma cutting has many advantages over dry cutting. It allows the operator to work at a deeper depth and is more effective for thinner-than-usual materials. However, not all materials are suitable for underwater plasma cutting, and a plasma torch specifically designed for cutting under water will provide the best value.
Underwater plasma cutting is a safe way to cut structural steel. The process reduces noise pollution, radiation, dust, and material distortions that are caused by heat input. Because the plasma beam is shielded by the water, underwater cutting can reduce noise and smoke. However, the process will not give you the cutting quality of a dry plasma cut.
Stainless steel and aluminum can be cut underwater. However, a minimum thickness of two inches is recommended. For optimal results, the plate should be submerged in two to three inches of water. A plate thinner than this will not reduce the noise or arc glare, but will reduce the speed of the cut and result in more dross at the bottom of the cut.
Plasma cutting produces
A great deal of cutting slag. The slag will have to be ground away after the process. This will add to the cost. Plasma cutting can also produce hazardous gases and arc light. The benefits of underwater plasma cutting outweigh these drawbacks. When you are looking to use this technology, don't be afraid to contact the professionals at Jacquet Metals.
Depending on the materials being cut, underwater plasma cutting, and Underwater drilling can be a great way to get the job done. The cutting process can be simple or complex. It requires a workpiece 11 and a plasma burner placed under water 30. During this process, a high-frequency discharge ignites the pilot arc 31 which ionizes the plasma cutting gas. The cutting arc then forms between the workpiece and the electrode 13.
This type of cutting is commonly used for steel, stainless steel, and aluminum. The plasma arc can be used to cut materials of various thicknesses from 0.5 mm to 180 mm. The process can be very accurate and cost-effective, and is suitable for many different applications. For instance, it can be used for underwater repair of submarines and other objects.
