  • Gas-Cutting: Process, Techniques and Advantages | Welding

    The process consists of preheating the metal to be cut to its ignition (oxidation) temperature, i.e., above 870°C in case of steel. The preheating is done by oxy-acetylene gas flame, which is supplied from surrounding openings of the cutting torch. When this temperature is attained, a jet of high pressure oxygen from a central opening of the cutting torch is directed on the red hot metal.

  • Unique CO2 Laser Machines for Engraving and Cutting | AP Lazer

    Cutting Our laser cutting machines use powerful CO2 gas lasers that can cut through most materials like wood, plastic, foam, fabrics, paper, and glass. With precision control from CNC integration, our laser machines can make precise cuts at speeds much faster than other mechanical cutting equipment.

  • What are the hazards from gases during welding and cutting ...

    Welding and cutting activities can generate gases that are hazardous to health. The gas or gases generated and their concentrations depend on the process used and the gas formation mechanisms. Gases, some of which may be hazardous, are inherent in some processes, either as a shielding gas to protect the molten weld pool against atmospheric ...

  • Gas equipment for CO2 laser cutting: A primer

    Jul 08, 2011 · Precise assist gas delivery is essential in CO2 laser cutting. The resonator is a key component, especially if gas delivery will be uninterrupted for unattended machine operation. Assist gas volume and pressure also must be appropriate for the application to ensure the best results.

  • CO2 Laser Cutting Machines - BuchiCNC

    The Co2 laser cutting and engraving machines work with an optical system that reflects a laser beam on the material. The laser beam is produced inside a glass tube that has gas inside it. It is reflected by means of three mirrors and is focused with a lens.

  • Co2 Cutting and Engraving Machine – MornTechUSA – Laser ...

    CO2 Laser Engraving Machine. MornTechUSA laser engraving machine offers precise and aesthetical engraving and cutting of non-metal materials. The machine primarily uses CO2 gas along with electricity to produce a laser beam that can cut through or engrave most materials. A glass tube helps to focus laser beam onto the surface of the material, the beam goes down the tube and out the nozzle through focus …

  • CO2 Laser Cutting Machines | Laser Cutter | HSG LASER

    CO2 Laser Cutting Machines. The laser beam used by the CO2 laser cutting machine is generated using CO2 gas and sent to the cutting head through a reflecting mirror. The CO2 laser cutting machine is used to cut …

  • Machining with Advanced CO2 Machining Spray Technology ...

    Sep 01, 2007 · Carbon dioxide (gas, solid, liquid) as a machining fluid and its beneficial impact on machining operations with regards to both lubricating and cooling qualities has been studied for the past 60 years. One of the earliest documented metal cutting processes using a carbon dioxide spray is described by Thompson Products (later TRW) in the early 1950s. 1 The literature contains several good examples of the benefits that can be realized with a CO 2 -based machining …
