Cutting Steel Underwater

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

Cutting steel underwater.

Welding equipment broco and arcair make high quality underwater welding and cutting equipment including torches stingers and cutting and welding rods. The system includes the broco br 22 plus torch uw ks knife switch and hvr 4401 regulator and broco exothermic cutting rods. 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.

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. 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. 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.
