The purpose of the work was to determine the hygienic characteristics of electromagnetic fields created by various methods of electric arc welding. For this purpose, an analysis of literature data on the electromagnetic safety of electric arc welding was performed. The levels and spectral composition of magnetic fields created by arc welding equipment in various ways were determined in order to assess their impact on the health of the welders. A description of the proposed methodical approaches to determining the level of magnetic fields, means of measuring them, and methods of assessing their impact on the welder's health is given. Modern regulations regarding the assessment of electromagnetic field effects on humans are characterized, as well as their difference from the regulations that were in force until recently. It is shown that new publications about the harmfulness of electromagnetic fields when using electrical production equipment began to appear. Therefore, there was a need to conduct new studies of electromagnetic fields, in particular their magnetic component (magnetic field strength, A/m) when using welding equipment. This is necessary for the hygienic assessment of magnetic fields and the development of appropriate methods and means of protection for welders. To do this, it was necessary to select new generation devices for determining the intensity of magnetic fields created by welding equipment. Based on the analysis of the obtained oscillograms and spectrograms of the magnetic fields, their levels were evaluated when using different methods of arc welding. It is shown that the spectral composition of the magnetic field signal is mainly determined by the welding method itself, the characteristics of the arc combustion and the nature of the transfer of the electrode metal in the arc gap, as well as the initial parameters of the welding arc power sources.
