Background

The electric welding mask is a tool for protecting the safety of operators in welding and cutting operation, mainly protects the eyes and the face of the operators, and effectively reduces the harm to the human body caused by harmful gas, dust and the like released by welding. In field welding operations, welders often use conventional hand-held or head-mounted protective masks, which have a viewing window with a light-blocking lens in the viewing window.

At present, a large amount of welding masks with automatic light-changing filters are put into a welding field for use, can well protect eyes of welders, but cannot be applied to all scenes. For example, when the boiler is operated in a boiler furnace in the power industry, the operation space is narrow, overhead welding is sometimes needed, operation is sometimes needed on the side, a welder often needs to change the welding angle, the welding protective mask is repeatedly taken down and worn, and the light and shade change of ambient light can cause eye fatigue and even vertigo symptoms for the welder.

In addition, in the welding operation, the safety of the operators is protected, and the welding quality is ensured. For example, in the case of failure of the metal parts commonly used in power stations, the failure due to weld quality problems is very significant. However, since real-time data cannot be retained in the whole process during welding operation, it is often impossible to determine whether there is a problem in the actual welding process in the failure analysis at the later stage.

In summary, it is very important to provide a head-mounted welding protective mask capable of tracing a real-time welding process.
