Abstract
Method of X-ray photoelectron spectroscopy was used to establish the valent state of manganese compounds in the welding aerosol. Valent state of manganese compounds (Mn+4) was found in welding with basic electrodes. Analysis of dispersity of welding aerosol solid compound was performed using the method of laser granulometry.
