Abstract
Purpose
The purpose of this paper is to investigate the exposure of human workers to low and high frequency electromagnetic fields during operation of GMAW‐P welding machines.
Design/methodology/approach
First, a numerical parametric analysis of the current waveform has been performed in Matlab, with reference to the human exposure; then a simulation model of a full welding system has been implemented in Simulink/Matlab. The effect has been numerically quantified accordingly to European Standards EN 50444 and EN 50445.
Findings
Contributions to human exposure of specific parts of the current waveform have been evaluated. A new numerical implementation of a full welding system has been done.
Practical implications
The paper shows that there could possibly be improvement in the design of current waveforms, with respect to a reduced human exposure of workers to electromagnetic fields.
Originality/value
The paper presents a new numerical tool that can be useful since the design phase of a welding system for the evaluation of human exposure of workers to electromagnetic fields.
