The dangers of welding aluminium

However, the combination of the aluminium material and the MIG or WIG welding method creates a different harmful substance: ozone. This occurs as a result of the ultraviolet radiation from the oxygen in the air. The UV rays are then reflected on the bare aluminium surfaces, and can still form ozone even at somewhat of a distance from the weld.
