Abstract
Spatial distribution of magnetic field (MF) generated by resistance spot welding machine in the work zone was determined with allowance for its spectral composition. Results of experimental studies of the effect of welding process parameters and distance from current-conducting elements of the welding circuit on the index of exceeding the MF level, according to the current medical requirements, are presented. Recommendations on protection of welders from MF are suggested, which are intended for designers of resistance welding machines, technologists and users of these machines.
