Well, for obvious reason, we can't possibly hear the actual sound of that laser working because of the burning wreckage on background.
>“Gazobezopasnost” Firm together with Troitsk Institute of innovative and thermonuclear research have developed and produces “МЛТК-50” Mobile Laser Complex for gas industry due to necessity of remote cutting of metallic constructions during emergency & restoration work at gas, gas-oil, gas-condensate blowout wells, including burning ones.
>The periodically pulsing electric ionization CO2 - laser has radiation power of 50 kW. Laser ray of the unit can cut metal up to 80 mm thick at a distance up to
80 m, being remotely controlled. To determine the coordinates of metallic parts to be remotely cut, which can’t be seen because of smoke and flame of a burning well, the complex is equipped with a special laser locator, which controls the direction of a cutting laser ray. Laser can work during 1 - 10 Minutes with intervals between its activations about 30 Minutes.
>The complex is usually transported on two serial automobile semi-trailers. This equipment can be transported in containers by railway. The cooling system of the equipment is water self-propelled one. Electric supply of the unit is required about 600 kW to make the unit function. Operative service personnel of the unit consists of 3 persons.
