Gouging is used in joint preparation and for the removal of defective welds.
Gouging is similar to gas cutting. An oxyfuel gas flame heats up the piece to be worked to ignition temperature, and the cutting oxygen jet combusts and carries away the molten metal. The equipment is the same as in gas cutting; only the nozzle needs to be changed. In gas cutting, the cutting oxygen beam is directed at the work piece at a ninety-degree angle, while in gouging the oxygen beam is almost parallel with the surface of the piece to be worked.
An oxyfuel gas flame can also be used in flame cleaning, to clean surfaces of rust, mill scale, paint, grease and dust. Examples of processes include the treatment of steel and concrete surfaces, as well as of offshore constructions.
In gouging and flame cleaning, various fuel gases are used together with oxygen. By using ODOROX® (odorised oxygen) you can minimise the risk of fire and explosion always associated with fuel gases. The odour provides a timely warning of gas leaks.
Avoid risks by following the safety instructions for hot work.
