Abstract
The dependence of the specific precipitations and chemical composition of a hard component of welding aerosol on content of iron powder in electrode coating was established. The effect of content of potassium compounds in coating of rutile and basic electrodes on their sanitary-hygienic characteristics was considered.
 
Keywords: manual arc welding, electrodes, electrode coating, welding aerosol, coating composition, sanitary-hygienic characteristics, hard component, specific precipitations
