Why must the face mask for electric welding be made of white glass?
White glass is the lower angle of ordinary glass. Usually about 2 millimeters in thickness. The purpose is: to prevent black lenses from splashing pollution.
That piece of white glass is called an anti splash film. The traditional black glass mask not only can not effectively protect the eye, and the outside splash proof piece has a short service life and is easy to slag. SF (J Phu Carter) fully automatic dimming mask, using LCD LCD screen, double filter, effectively filter a variety of harmful light, effectively protect the eyes, and its anti splash film with splash, high temperature, non slag characteristics.
Black glass: filter mask for welding protective mask (welding cap). The spatter is unavoidable in welding process. White glass is cheap and easy to change. It also acts as a heat shield to protect the black glass from the sudden burst of welding heat.
Welders in welding, welding slag will splash into the mask and goggles, in order to let the black for a long time, the installation of a white sheet in front. You can observe the changed lenses, and there will be a lot of slag on them.
