WebStratospheric ozone (O3) is produced by the combination of an oxygen atom (O) with an oxygen molecule (O2). The basic steps to formation are: In the above diagram, oxygen atoms are represented as dark blue circles. This reaction is written in chemical equations as O2 + UV => O + O 2 O + 2 O2 + third molecule => 2 O3 + third molecule WebThe effect of welding process, material and current level on ozone generation and the resultant ozone levels in the welders breathing ozone have been determined under conditions of natural ventilation, ozone levels varying from 0·06 ppm for manual flux-covered electrodes, to 0·47 ppm for bare-wire argon-shielded welding of aluminium.
