A simplified procedure for the exposure to the magnetic field produced by resistance spot welding guns

摘要

This paper describes a simplified but effective methodology for the assessment of the human exposure to the magnetic field generated by resistance spot welding guns. The procedure makes it possible to compute the induced electric field in time domain as required by the standardized methodology for the assessment of pulsed magnetic fields (i.e. the weighted peak method). In this paper we show that the proposed procedure provides results in accordance with a rigorous approach allowing a huge reduction of the computational burden and, consequently, a significant speedup.
