Flame gouging is used to remove certain parts of a surface, for example to repair areas with welding defects.
The process is largely similar to oxy-fuel cutting. An oxy-fuel flame melts the material and an oxygen jet blows away the molten metal. Nevertheless, the position of the burners is quite different. In oxy-fuel cutting, the oxygen jet is directed towards the lower side of the work piece in order to produce a hole. In gouging, the oxygen jet is almost parallel to the work piece surface in order to produce a gap or remove a surface layer.
If the oxygen jet is reduced, this process can be used for flame cleaning. The energy from the oxy-fuel process supported by a small oxygen jet can be used to clean any material, including steel constructions, offshore systems and even concrete elements. Furthermore, rust, scale, paint, grease and dust can be removed.
Various fuel gases, together with oxygen, can be used to run the processes.
Working with fuel gases and oxygen can be risky if the person using the equipment does not have sufficient knowledge of the equipment and its installation, handling and care. |
