    摘要： An underwater cutting tool for steel, concrete, or the like, comprising a tubular oxygen lance (10) adapted to be connected to an oxygen source (24, 25) and having a pistol grip-like handle (16).Prior to its first use the lance is sealed so as to be ignited safely under water. This seal (12) is adapted to be blasted off or fused by means of an igniter unit (14) which is operable under water, at the same time, firing the oxygen flowing out of the lance (10). The seal (12) preferably is formed by a plug of a material which is easily inflammable or contains such material and hermetically seals the free end of the lance (10).

    摘要： A method for torch cutting metal walls by burning powdered metals admixed with a gas oxidizer to establish a pre-heat flame at a cutting zone and followed by continuously adding a gas cutting agent for intensifying said flame cutting through the metal wall by burning and melting, and an apparatus to implement this method and which locates a body to the wall to be cut and carries and advances a torch over said wall with the discharge of said powdered metals and gases for preheat and followed by the continuous addition of said cutting agent for continuous cutting of the wall, and all of which is adapted to remote underwater operation within steel casings and over steel plate, as well as through other metals and materials.
