The traditional welding process - your side potential killer

There are three aspects of the harmful factors affecting the human body by argon arc welding:

(1) radioactivity. Thorium tungsten is a radioactive element, but the radiation dose of thorium tungsten electrode is very small in the tungsten argon arc welding. If radioactive gas or particles enter the human body as internal radiation source, it will seriously affect the health of the body.

(2) high frequency electromagnetic field. The high frequency arc, high frequency electromagnetic field intensity produced between 60 ~ 110V/m and exceed the standard reference (20V/m) several times. However, due to a short time, little impact on the human body. High frequency electromagnetic field can be one of the harmful factors if the arc is frequently used, or the high frequency oscillator is used as a stable arc device in the welding process.

(3) harmful gases, ozone and nitrogen oxides. When the argon arc welding, the arc column temperature is high. Ultraviolet radiation intensity is much greater than the general arc welding, so in the welding process will produce a lot of ozone and oxygen nitrogen compounds, especially the ozone concentration is far beyond the reference health standards. If not to take effective ventilation measures, these gases have a great impact on human health, is the most important factor in argon arc welding.
