Abstract Electric and magnetic field (EMF) phenomena arise where applying manual arc welding equipment. Consequently, using such systems may cause adverse effects to welding personnel. Models available quantitatively to assess EMF impacts in welding consistently show underestimation of exposure; mainly due to simplified boundary conditions implemented to facilitate modelling application. For arc welding this paper introduces a novel approach, namely, the implementation of Induction Factors to improve EMF exposure assessment quality. Moreover, it is shown in how far especially advanced MIG / MAG and TIG welding variants for example involving additional hardware that may produce EMF effects, are represented deploying the standards existing. Results are presented and discussed both found in practical process application and numerical simulation. Employing the developed calculation approach is capable of compensating for inaccuracies yet identified with models still recommended by regulatory- or professional bodies. Users are provided with comprehensive information to help practically evaluate EMF exposure.
