Determining patterns in the generation of magnetic fields when using different arc welding techniques

This paper reports a study into the levels of magnetic fields induced by arc welding equipment in various ways order to assess their impact on body welders. It is known that welders are exposed field high intensity. Depending technique and type equipment, it may exceed maximum permissible (MPL). Note new Ukrainian sanitary standards for have been introduced, which regulate depending frequency range. Therefore, became necessary carry out hygienic assessment according devise appropriate methods protecting To this end, was required choose generation devices determine intensity equipment. Based analysis constructed oscillograms spectrograms fields, found semi-automatic with metal electrode carbon dioxide characterized an increased level range 50‒1000 Hz. With automatic under flux, there no excess individual harmonics but total value all harmonic components field. Manual direct current involving non-melting argon moderate workplace. During manual coated electrodes, exceeded observed only cable itself. shown spectral composition signal determined mainly itself, peculiarities combustion, nature transfer gap, as well initial parameters power supplies
