Abstract

The electric arc welding process makes use of the heat produced by the
electric arc to fusion weld metallic pieces. An electric arc is formed when an electric current
passes between two electrodes separated by a short distance from each other. The aim of this
work is to determine the electromagnetic field strength emitted by different electrical welding
machines at different ranges and identify the safe ranges in order to avoid its negative health
effects on the welder body. The research has been performed in two parts, mathematical
calculations and practical measurements using (EMF-827) field tester. Both measurements
indicate that these exposure levels lie within permissible international standard limits , but in
some very close to the torch the values of magnetic filed are above the standard permissible
values, so there is no harm to human health if the exposure is for an intermittent and
discontinuous periods.
