Oxygen Fuel Gas Welding

What is Oxy-fuel welding?

Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the United States) and oxy-fuel cutting are processes that use fuel gases (or liquid fuels) and oxygen to weld or cut metals.

Oxy-acetylene welding:

Gas welding in which the fuel gas is acetylene. Note: Other fuel gases are also used with oxygen (i.e. butane, hydrogen, and propane).

  • Welding or Cutting Hoses

    a. Do not allow hoses to come in contact with oil or grease. These will penetrate and deteriorate the rubber and constitute a hazard with oxygen. b. Always protect hoses from being walked on or run over. Avoid kinks and tangles. Do not leave hoses where anyone can trip over…

  • Oxygen and Oxygen Production

    Oxygen and Oxygen Production a. * Oxygen* is a colorless, tasteless, odorless gas that is slightly heavier than air. It is nonflammable but will support combustion with other elements. In its free state, oxygen is one of the most common elements. The atmosphere is made up of approximately 21 parts of…

  • Welding Oxyfuel Working Pressure

    The required working pressure increases as the tip orifice increases. The relation between the tip number and the diameter of the orifice may vary with different manufacturers. However, the smaller number always indicates the smaller diameter. For the approximate relation between the tip number and the required oxygen and acetylene…

  • Setting up Oxyacetylene Welding Equipment

    WARNING Always have suitable fire extinguishing equipment at hand when doing any welding. When setting up setting up oxyacetylene welding equipment, it is important that all operations be performed systematically in order to avoid mistakes and possible trouble. The setting up procedures given in a through d below will assure…

  • Stationary Oxyacetylene Welding Equipment

    Stationary oxyacetylene welding equipment is installed where welding operations are conducted in a fixed location. Oxygen and acetylene are provided in the welding area as outlined below. Oxygen. Oxygen is obtained from a number of cylinders manifolded and equipped with a master regulator. The regulator and manifold control the pressure…
