Cutting Steel Underwater

Cast iron stainless steel and non ferrous metals do not oxidize.

Cutting steel underwater.

Therefore underwater cutting becomes a melting process. The system includes the broco br 22 plus torch uw ks knife switch and hvr 4401 regulator and broco exothermic cutting rods. Oxygen arc cutting advantages of the steel tubular electrodes. Welding equipment broco and arcair make high quality underwater welding and cutting equipment including torches stingers and cutting and welding rods.

They perform efficient cutting and will burn through steel concrete rock coral marine growth and other non conductive materials when the power is off. Heat distortion occurs when you heat up one part of a plate and then let it cool causing uneven expansion and contraction. Cutting under water keeps the entire plate cooler which reduces warping of the cut parts and the skeleton or scrap plate. Here is a short vid of some underwater cutting of steel with a exothermic torch and firewire rod.

The co23 uses standard 10 inch 25 4 cm diameter abrasive or wet or dry diamond blades for cutting metals or concrete.
