Welding solitary light radiation can cause electro-optical eye inflammation is what
Arc welding: the use of high temperature melting metal parts need to connect the place, in the temperature field, gravity, etc., the two parts of the molten melt will be mixed, after cooling into a whole process.
Arc light: refers to the light emitted by the arc. Which contains a lot of ultraviolet light.
Electro-optic ophthalmia and snow blindness, are ultraviolet rays on the cornea and conjunctival epithelium caused by damage caused by inflammation. Characterized by swelling of the eyelids, conjunctival hyperemia edema, severe foreign body sensation and pain, the symptoms are afraid of light, tears and eyes open, the disease will be blurred during the situation.
UV refers to the electromagnetic spectrum in the wavelength from 10nm ~ 400nm radiation in general, can not cause human vision. But will cause great harm to the human eye.
Ultraviolet.
Arc: is a gas discharge phenomenon. Metal surface due to a single electron emission led to the escape of electrons, gas atoms or molecules in the gap due to ionization and produce electrons and ions. In addition, electron or ion bombardment of the launch surface will cause secondary electron emission. When the ion concentration in the gap is large enough, the gap is electrically charged and the arc is generated. After the two electrodes contact and then open and maintain a certain distance, you can form the arc.
