HYGIENIC CHARACTERISTICS OF WORKING ZONE AIR IN ARC WELDING OF COPPER AND ITS ALLOYS (Review).

A literature review of harmful substances formed in arc welding of copper and its alloys is presented. Literature data on studying emissions of welding aerosols in welding of copper and copper alloys are considered. It is shown that to create new grades of welding materials that would satisfy not only their welding technology, but also sanitary and hygienic characteristics, it is necessary to continue the study of chemical composition and levels of emissions of welding aerosols using modern standardized international procedures.
