Of course, metal welding is one of the most dangerous for humans, because all welding work is accompanied by a constant release of harmful substances and factors. Some of the most dangerous are: electric arc, bright glow, toxic gases, infrared and ultraviolet radiation. That is why, in order to protect themselves as much as possible from such a "bouquet" of troubles, when welding metal, workers use a special protective mask, which is called the welder's mask.
Arc Hazard
First, let's note why an electric arc is so dangerous for a person. This is in the process of such work is the basis of the basics of electric arc welding. At the same time, the temperature of metal nodes can reach 8 or more thousand degrees. With such heating, a local melting of steel occurs, due to which the connection is very high quality and reliable. But the "side" effect here is intense radiation in infrared, optical and ultravioletrange. All this glow has a very negative effect on the eyes of the worker, which can lead to various diseases and even complete loss of vision. Therefore, the welder's mask is an essential attribute when performing this kind of work.
Varieties
To date, there are 4 main types of these devices:
- Traditional mask.
- Welding shield.
- Mask for specific work.
- Attachment with special lifting filter.
Absolutely each of these types is supplied with thick tinted glass. Also, a welder's mask (including ASF) may have a special light filter in its design, which includes a cover glass and a Plexiglas substrate.
Glass design
This part of the tool is made of a special non-conductive material, which, by its properties, is resistant to splashes of metal heated to 8 thousand degrees Celsius, sparks and electric arcs. It is best to purchase masks that have removable mechanisms for replacing this glass. The fact is that during prolonged welding, its surface is very quickly “splattered” with metal splashes and it is almost impossible to see the welding spot through such a tool. Therefore, make sure that the device has a removable glass mechanism (with a sealed mount).
Producers
The following are the most sought-after companies that are engaged in the production ofdetails such as a welder's mask:
- "Corund".
- Chameleon.
- Fubag.
- Elitech.
- Speedglas.
- Kemppi.
The most expensive welder's mask, and therefore the highest quality in terms of its characteristics, is the product of the Chameleon company. It costs more than all the other "brothers" - about 2-2.5 thousand rubles. And this despite the fact that some types of masks can be purchased for 160-200 rubles. In general, the cost of quality parts varies from 1 to 2 thousand rubles.
When choosing, pay special attention to the fact that the mask is conveniently adjusted "under the head" and not too heavy.

Passivation is The process of passivation of metals means the creation of thin films on the surface in order to protect against corrosion
Traditional methods of protecting metals from corrosion are less and less likely to meet the technical requirements that apply to the performance properties of critical structures and materials. Bearing beams in house frames, pipeline lines and metal claddings cannot do without mechanical rust protection alone when it comes to long-term use of the product. A more effective approach to corrosion protection is the electrochemical method and in particular passivation
