The levels and spectral composition of magnetic fields, generated by equipment for arc welding by different methods were
determined, in order to assess their influence on the welder body. Published data on electromagnetic safety of electric arc
welding were analyzed. A description of the proposed methodological approaches to determination of magnetic field levels,
their measurement methods and methods of assessment of their influence on the welder body is given. Modern standards are
characterized as to evaluation of the electromagnetic field impact on man, and their difference from the earlier applied standards.
It is shown that new publications began to appear recently, which are devoted to the harmfulness of electromagnetic fields at
application of electric production equipment. Hence the need to conduct new studies of electromagnetic fields, in particular their
magnetic component (magnetic field intensity, А/m), when using welding equipment. This is required for hygienic assessment
of the magnetic fields and development of the respective methods and means of welder protection. For this purpose, it will
be necessary to choose new generation instruments for determination of the intensity of the magnetic fields. Proceeding from
analysis of the obtained oscillograms and spectrograms of the magnetic fields, evaluation of their levels was performed at application
of different arc welding methods. It is shown that the spectral composition of the magnetic field signal is determined,
predominantly, by the welding process proper, features of arc burning and mode of electrode metal transfer in the arc gap, as
well as output parameters of the welding arc power source. 10 Ref., 5 Tabl., 3 Fig.
