Abstract

The utility model provides a welding protective mask which is used for seeing the welding spot of a welded object through a lens without moving the mask when a welder knocking the welding spot. The welding protecting mask comprises a panel, a side plate, a filter lens and a visual mechanism, wherein the visual mechanism can be used for directly observing the position of the welding spot of the welded object from the inside of the mask to the outside of the mask through the filter lens and can be opened or closed. The visual mechanism is a visual window component arranged on the panel or a high-brightness spotlighting part arranged on the panel or the side plate. According to the welding protective mask, the welder does not need to repeatedly move away the mask to see the welding spot and then move back the mask for welding in the process of knocking the welding spot at the initial period of welding, in the whole welding process, the mask is worn on the head of the welder and is not moved away, when the welding spot is knocked, an opening-closing mechanism or a switch button of the visual mechanism can be slightly shifted or opened by the free hand, and the welding spot can be seen clearly. The eyes of the welder are protected, the working efficiency of the welder is also improved, the welding condition can be known at any time, and the welding quality is guaranteed.
