Does a cutting torch work underwater?

At the same time, oxygen contained in the atmosphere sustains the flame. These two elements manifest in an underwater cutting torch. The combustible supply and oxidizer are provided by the hoses, leading to the torch since oxygen is unavailable underwater.

How is underwater cutting done?

It uses a standard type thermic electrode, which has a small hole down its centre through which pressurised oxygen flows to make the cut. Oxygen stream causes intense oxidation of the material of the electrode, giving the heat for cutting the metal; the cut is blown away by the oxygen stream.

What gas is used for underwater cutting?

Detailed Solution

Fuel Gas	Supporter of combustion	Application/uses
Liquid petroleum gas (LPG)	Oxygen	Used for gas cutting steel heating purposes. (Has moisture and carbon effect in the flame.)
Acetylene	Air	used only for soldering, brazing, heating purposes and lead burning.

How does a torch burn underwater?

The combustible gas, which might be hydrogen or acetylene, depending on the application, can be combined with oxygen gas (the oxidizer) to produce an underwater flame at the tip of the torch.

What metal burns underwater?

Thermite, a mixture of rust and aluminum. YouTube/TheBackyardScientist This flowerpot full of red powder looks pretty innocuous. But when ignited with a strip of magnesium and a blowtorch, it yields a molten metal so hot it keeps burning underwater.

Can you light a flare underwater?

The combustible gas, which might be hydrogen or acetylene, depending on the application, can be combined with oxygen gas (the oxidizer) to produce an underwater flame at the tip of the torch. …

Which burns hotter acetylene or propane?

Acetylene releases almost 40\% of its heat in the inner flame cone. Therefore, acetylene is better for cutting than propane. While temperature wise acetylene is hotter than propane the fact is that people are using propane for cutting incorrectly.

How thick can an oxy-acetylene torch cut?

Oxy-acetylene torches can easily cut through ferrous materials in excess of 200 mm (8 inches). Oxygen lances are used in scrapping operations and cut sections thicker than 200 mm (8 inches).

Can oxy acetylene be used underwater?

Underwater cutting of Metals can be performed by Oxy-acetylene, Oxy-hydrogen or Oxy-electric . Oxy-hydrogen is not as hot as Oxy-acetylene but can be used at greater depths. Compressed air is used to provide a protective shroud around the flame which in turn means the flame does not go out when immersed in water.
