  1. Fulltext. The effects of welding parameters on ultra-violet light emissions, ozone and CrVI formation in MIG welding.

    Article - En anglais

    Fulltext.

    This paper describes the relationships between ultra-violet emission, ozone generation and CrVI production in MIG welding which were measured as a function of shield gas flow rate, welding voltage, electrode stick-out and shield gas composition using an automatic welding rig that permitted MIG welding under reproducible conditions.

    The experimental results are interpreted in terms of the physicochemical processes occurring in the micro-and macro-environments of the arc as part of research into process modification to reduce occupational exposure to ozone and CrVI production rates in MIG welding.

    We believe the techniques described here, and in particular the use of what we have termed u.v. - ozone measurements, will prove useful in further study of ozone generation and CrVI formation and may be applied in the investigation of engineering control of occupational exposure in MIG and other welding process such as Manual Metal Arc (MMA) and Tungsten Inert Gas (TIG).
