Underwater Cutting

Cutting, Gouging and Piercing

Underwater cutting is often referred to in the commercial diving industry as Broco Cutting. ‘Broco’ is a brand name for manufacturing and developing underwater cutting and welding systems. The cutting method can also be referred to as thermal lance cutting. The thermal lance cutting system was developed for fast and efficient means of cutting, piercing or gouging metals underwater.

Underwater Ultrathermic Cutting Systems use only industrial type bottled oxygen and approximately 150-200 amps. Ultrathermic Cutting Rod readily ignites from a spark supplied from the surface i.e. DC welder and will continue to burn with the electrical current removed until the flow of oxygen is stopped or the cutting rod is consumed. The need for expensive support equipment is reduced while at the same time a safer diving environment is maintained. The recommended oxygen working pressure of 90 psi over bottom.

The ultrathermic cutting rod produces a temperature in excess of 5,500 degrees Celsius – hot enough to quickly cut or melt through almost anything including cast iron, stainless steel, brass, other ferrous and non-ferrous metals and concrete.

Other underwater cutting techniques such as carbon arc gouging can also be very useful for controlled and fine detail gouging and cutting required in certain circumstances to reduce the risk of shell plate damage in shipping.
