Welding is a metal processing that joins two or more solid metals into one. A high energy heat source is required for welding, and high-pressure and explosive gases such as high voltage electricity, oxygen, acetylene, and argon are used as such energy sources. The hazards and dangers caused by welding are due to the welding fume (metal components contained in the fume) or harmful gases, harmful rays, noise, and high temperature environment generated during welding.

In particular, when arc welding in a narrow and closed workplace, welding workers are injured by the welding fumes and nitrogen oxides generated during the welding process, and recently, they are contained in manganese as well as pneumoconiosis (welding pneumonia) caused by welding. Manganese poisoning accidents have occurred due to the use of used welding electrodes, and measures for health problems of welding workers are required.

The welding fume refers to a small particle formed by the cooling of a material evaporated by heat during welding, and is caused by the diffusion of molten metal vapor around by high temperature arc generation heat. The relationship tends to increase with increasing current, voltage, and electrode diameter.

On the other hand, the harmful gas generated by welding has not been noticed as much as the welding fume, the recognition of the hazard is lower than the welding fume. However, there are various types of harmful gases, such as ozone, nitrogen oxides, carbon monoxide, carbon dioxide, hydrogen fluoride, phosgene, phosphine, products by pyrolysis of paints and coating components, and so must be as careful as welding fumes.

Conventionally, it is used to protect workers from the harmful rays generated during arc and gas welding and cutting operations, and to protect workers from the risk of burns caused by debris, such as thermal burns on the face and neck, and heated materials. A lot of shading welding surfaces have been used.
