| Description |
Chemical analysis of flux-cored wire NR-207 deposited metal by a method of optical emission spectrometry makes it possible to determine the influence of the composition of flux-cored wire NR-207 on the emission and chemical composition of the welding aerosol. Chemical composition of deposited metal is a complex index of chemical composition of metal cover and wire core. Such dangerous substances as compounds of manganese, fluorine, aluminum, nickel, and fluorinated gases are released during welding with wire NR-207 into the working space of a welder.
