Description

Weld mask to remove moisture with wiper function}

The present invention relates to a welding mask capable of removing moisture with a wiper function, and more particularly, by attaching a wiper movable left and right to the inside of the protective glass of the welding mask, which occurs on the protective glass due to worker breathing during welding work. The present invention relates to a welding mask capable of removing moisture with a wiper function capable of easily removing possible moisture and improving welding quality due to easy visibility during welding work.

In general, electric arc welding, oxygen welding, inert gas welding, and special welding methods are used as welding methods for interconnecting metals, and welding by melting a welding rod while generating an arc using electrical energy, or using acetylene gas and oxygen. The welding rods are melted by spraying together, and welding for interconnecting metals may be performed while melting the welding rods by using inert gas or the like or by using heat from light rays.

When performing the above welding, since strong rays and harmful gases are generated in the area where welding is performed, in general, the worker wears a welding mask to protect the eyes and skin of the worker from the strong rays and harmful gases. Welding masks can be largely divided into oxygen welding masks and electric welding masks. Oxygen welding mask used for oxygen welding where the brightness of the spark is relatively small, the entire field of view protection is formed of a semi-transparent plate, so it is not only easy to cut through the field of view protection that becomes a semi-transparent plate when working, but also without removing the welding mask. It has a feature that can perform even simple tasks of. In the case of electric welding masks used for electric welding with high welding sparks, the light blocking effect of the field of view protection is great, so the part other than the welding part is not visible when welding through the field of view protection, unless the electric welding mask is removed. It has the characteristic that it cannot perform other simple tasks.

If both the oxygen welding mask and the electric welding mask are worn on the head in common for a long period of time welding, the protection glass of the welding mask is fogged due to moisture generated by the worker's breathing. Since the location is not properly identified, even a skilled person does not properly understand the welding location, so that the welding work is performed with intuition or guesswork, and precise work becomes impossible, and there is a problem that there is a large risk of safety accidents.

Therefore, if it is difficult to secure the front view due to fogging on the protective glass when performing welding work, the operator can accurately check the welding part surface of the object to be welded with the naked eye while raising the welding mask, and check the humidity at a constant level. After removing the degree, there was an inconvenience of wearing the welding mask again to perform the welding operation. In some cases, when performing precise welding work, there is a risk of damage to the eyes of the worker by performing welding without wearing a welding mask in order to fundamentally avoid the above inconvenience. do
