Underwater Plasma Cutting The development of underwater plasma cutting originated in the special requirements of industrial cutting applications. Among other things, the noise pollution, radiation and dust exposure as well as material distortions caused by heat input should be reduced.
Plus, the small footprint of our concrete saw cutting equipment eliminates disruption to surrounding operations, reducing line downtime and minimizing cost. Flexible in Traffic, Restricted Access and "Live" Production Facilities With their small footprint and remote operation, our diamond wire saws excel at underwater concrete cutting, and at cutting on confined space and limited access ...
E-2.1 Arcwater Cutting. Water arc cutting is essentially a melting process. Water is used to blow the molten metal out of the kerf. Since the cutting is dependent solely on the melting action of the arc, all the power available, up to 500 amps may be used.
Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment. Immersion in water and exposure to high ambient pressure have physiological effects that limit the depths and duration possible in ambient pressure diving.
Counter to most topside welding processes, controlling underwater welding equipment is a partnership of the divers below and the control team on the boat. Just before the welder-diver is ready to start the weld, he or she will communicate via radio to the control team.
This manual discusses underwater cutting and welding, the equipment, and provides information on underwater safety practices. The Arcair Underwater Products is a complete line of underwater cutting and welding torches, electrode holders, and underwater cutting and wet welding electrodes. The underwater environment puts special limits and restrictions on the operator by limiting time on the ...
Underwater thermal cutting refers to the exothermic process of cutting materials (such as ferrous metals) with a tool that combines oxygen and heat to oxidize or melt the materials. It is often called Broco© cutting, named after one of the most common systems used for cutting under water.
Underwater oxygen arc cutting and shielded metal arc cutting and welding are performed with basically the same equipment. A typical arrangement of this equipment is illustrated in Figure 4-1; additional accessories not shown include scrapers and wire brushes which are used for both underwater cutting and welding operations.
