| Gouging is used to remove surface impurities, for example to repair areas with welding defects.
The process is similar to oxy-fuel cutting. An oxy-fuel flame melts the material to be removed and an oxygen jet ignite, burn and blows away the molten metal. However, burner position is quite different. With oxy-fuel cutting, the oxygen jet is directed towards the lower side of the workpiece in order to produce a hole. With gouging, the oxygen jet is almost parallel to the workpiece surface in order to produce a gap or remove a surface layer.
If the oxygen jet is reduced, this process is ideal for flame cleaning. An oxy-fuel flame with a low small oxygen jet can be used to clean any material, including steel constructions, offshore systems and even concrete blocks.
It is also perfect for the removal of rust, scale, paint, grease and dust.
Oxygen can be combined with a choice of fuel gases to best suit individual application needs.
