OVERLAP
The protrusion of weld metal beyond the bond at the toe of the weld.
OXIDIZING FLAME
An oxyacetylene flame in which there is an excess of oxygen. The
unburned excess tends to oxidize the weld metal.
OXYACETYLENE CUTTING
An oxygen cutting process in which the necessary cutting temperature
is maintained by flames obtained from the combustion of acetylene
with oxygen.
OXYACETYLENE WELDING
A welding process in which the required temperature is attained by
flames obtained from the combustion of acetylene with oxygen.
OXY-ARC CUTTING
An oxygen cutting process in which the necessary cutting temperature
is maintained by means of an arc between an electrode and the base
metal.
OXY-CITY GAS CUTTING
An oxygen cutting process in which the necessary cutting temperature
is maintained by flames obtained from the combustion of city gas with
oxygen.
OXYGEN CUTTING
A process of cutting ferrous metals by means of the chemical action of
oxygen on elements in the base metal at elevated temperatures.
OXYGEN GOUGING
An application of oxygen cutting in which a chamfer or groove is
formed.
OXY-HYDROGEN CUTTING
An oxygen cutting process in which the necessary cutting temperature
is maintained by flames obtained from the combustion of city gas with
oxygen.
OXY-HYDROGEN WELDING
A gas welding process in which the required welding temperature is
attained by flames obtained from the combustion of hydrogen with
oxygen.
OXY-NATURAL GAS CUTTING
An oxygen cutting process in which the necessary cutting temperature
is maintained by flames obtained by the combustion of natural gas with
oxygen.
