Gouging

Flame or Oxy-fuel Gouging

Flame gouging is a variant of conventional oxy-fuel gas welding. Oxygen and a fuel gas are used to produce a high temperature flame for melting the steel. When gouging, the steel is locally heated to a temperature above the 'ignition' temperature (typically 900°C) and a jet of oxygen is used to melt the metal - a chemical reaction between pure oxygen and hot metal. This jet is also used to blow away molten metal and slag. It should be noted that compared with oxy-fuel cutting, slag is not blown through the material, but remains on the top surface of the work piece. The gouging nozzle is designed to supply a relatively large volume of oxygen through the gouging jet. In oxy-fuel gouging, equal quantities of oxygen and acetylene are used to set a near-neutral preheating flame. The oxygen jet flow rate determines the depth and width of the gouge.

I use high-pressure gas cylinders and am concerned about safety. Is there a better way?

Traditionally, high-pressure gas cylinders have been the supply mode for users in the low to medium volume range. Air Products CryoEase® microbulk service consolidates your gas supply to a centralized system eliminating the need to handle cylinders and ensures the right gas is delivered to your use point. Further benefits of the CryoEase® microbulk service include decreased exposure to high-pressure containers and reduced traffic congestion with less frequent supplier deliveries. Air Products developed the microbulk supply option as a cost-effective, reliable alternative to high-pressure cylinders for nitrogen, argon, oxygen and carbon dioxide supply. In addition to efficient and flexible storage systems, innovative piping solutions are available to help you have a smooth transition from cylinders to microbulk.
