Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields
Welding current 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
