  • Oxy-fuel welding and cutting - Wikipedia

    The laser cutting process of some materials, such as carbon and some ceramics, purely belongs to the gasification process. The laser cutting of metal mostly adopts high power carbon dioxide continuous laser generator. When cutting, spray the inert gas flow, blow out the incision to melt the metal, and make the incision smooth and straight.

  • Nitrogen vs. Oxygen: Which Should You Use to Cut Steel ...

    Cutting Machine. a machine used for cutting out parts of articles from layers of cloth card webs or knitted fabric. The technically possible depth of cutting of the layer depends on the design of the cutting machine and on the thickness and properties of the fabrics. Cutting machines may be movable or stationary.

  • What equipment is used for gas welding?

    Prevent an explosion from such a reaction by treating such cutting as if high-pressure gas is inside the compartment when you start cutting. The Centers for Disease Control and Prevention also says to use equipment specifically designed for drilling through high-pressure gas lines or, if possible, working remotely, using automated equipment.

  • Oxygen Cutting - an overview | ScienceDirect Topics

    Oxy-fuel cutting torches use a copper tip with a series of holes arranged in a circle to deliver a mixture of a fuel gas and oxygen to create a pre-heat flame. Preheat flame temperatures will range from 4,440° to 6,000° F depending upon the fuel gas used and the adjusted ratio of oxygen to fuel gas.


    The oxygas cutting torch has many uses in steel-work. At most naval activities, the Steelworker finds the cutting torch an excellent tool for cutting ferrous metals.

  • Oxy-Acetylene Cutting Processes | Metallurgy

    Gases used in welding and cutting processes include: shielding gases such as carbon dioxide, argon, helium, etc. fuel gases such as acetylene, propane, butane, etc. oxygen, used with fuel gases and also in small amounts in some shielding gas mixtures.

  • Metal Cutting Machine

    Jul 08, 2011 · Let’s start the virtual checklist by breaking down the CO 2 laser into its two main working parts. 1. Resonator. The resonator is the part of the laser that creates the cutting beam. It requires high-purity (grade 5 or better) CO 2, nitrogen, and helium. Carbon monoxide sometimes is added to the resonator gas mix, depending on the resonator manufacturer.

  • How Plasma Cutting Works and What Is Plasma Cutting

    Nov 09, 2018 · Laser cutting can only produce a clean edge if you use an assist gas to blow away molten material. Traditionally, oxygen has been the gas used, but nitrogen offers many advantages for cutting steel. Explore the benefits of nitrogen cutting when working with mild steel, stainless steel, and aluminum.

  • How to Use a Plasma Cutter - Beginner Welding Guide

    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.
