Considerations About Welding And The Effects Of Low
Frequency Electric And Magnetic Fields
Welding current, as it flows through welding cables,
will cause electromagnetic fields. There has been
and still is some concern about such fields. However,
after examining more than 500 studies spanning 17
years of research, a special blue ribbon committee of
the National Research Council concluded that: “The
body of evidence, in the committee’s judgment, has
not demonstrated that exposure to power-frequency
electric and magnetic fields is a human-health hazard.”
However, studies are still going forth and evidence
continues to be examined. Until the final conclusions
of the research are reached, you may wish to minimize
your exposure to electromagnetic fields when welding
or cutting.
To reduce magnetic fields in the workplace, use the
following procedures:
1. Keep cables close together by twisting or taping
them, or using a cable cover.
2. Arrange cables to one side and away from the
operator.
3. Do not coil or drape cables around your body.
4. Keep welding power source and cables as far away
from operator as practical.
5. Connect work clamp to workpiece as close to the
weld as possible.
About Implanted Medical Devices:
Implanted Medical Device wearers should consult
their doctor and the device manufacturer before
performing or going near arc welding, spot welding,
gouging, plasma arc cutting, or induction heating
operations. If cleared by your doctor, then following
the above procedures is recommended.
