Cutting Steel Underwater

Oxygen arc cutting advantages of the steel tubular electrodes.

Cutting steel underwater.

Therefore underwater cutting becomes a melting process. They perform efficient cutting and will burn through steel concrete rock coral marine growth and other non conductive materials when the power is off. The system includes the broco br 22 plus torch uw ks knife switch and hvr 4401 regulator and broco exothermic cutting rods. Cast iron stainless steel and non ferrous metals do not oxidize.

The co23 uses standard 10 inch 25 4 cm diameter abrasive or wet or dry diamond blades for cutting metals or concrete. 10 15 gpm 38 57 lpm operating range. Heat distortion occurs when you heat up one part of a plate and then let it cool causing uneven expansion and contraction. Co23 cut off saw the stanley co23 cut off saw was designed for underwater use but it is also a very useful tool on land as well.

Here is a short vid of some underwater cutting of steel with a exothermic torch and firewire rod.
