Types of welding glasses. Welding glasses-chameleons - the newest protection

The profession of a welder is important and in demand, a specialist in his business will always be at work. Qualitatively, the seam will be helped by experience and knowledge, and to be protected from industrial trauma during welding works - means of individual protection.

The most common injury in this profession is a burn of the eyes or skin. It can be obtained when working with a gas burner, semi-automatic welding or during manual arc welding. Sparks of hot metal and flying sparks that hit the eyes cause serious injury. Open skin is protected by a special non-combustible welding robe, long leggings are worn on the hands, and eyes and a face are covered with special glasses.

Welding goggles

Safety rules require the welder to work in individual protective equipment. These include special glasses. They are made of dense plastics, resistant to aggressive environment.

They should be well fixed on the head and snug against the face. Glasses are used to protect the worker's eyes from bright light during welding or plasma cutting of metal, from incandescent sprays and hot sparks. Welding goggles are necessarily supplied with protective light filters that protect the eyes from infrared and ultraviolet radiation when working with hot metal. The filters, installed on the glasses, are divided into three categories according to the degree of darkness and are used for welding works of different intensity:

1. At the open area.

2. With an average power.

3. At high power.

Filters are installed over glasses with conventional glasses in a rotating additional frame. They can be lowered at the beginning of welding operations and raised at the end or in order to see the quality of the seam.

Most popular glasses

Modern industrial technology has made welders a wonderful gift. Created the newest means of individual protection - welding glasses-chameleons.

The features of these glasses are that the darkening of the glasses in them occurs automatically at the first flash. When the intensity of light decreases, the glass becomes lighter, and becomes almost transparent under normal lighting conditions. The employee does not have to be distracted, take off his glasses, to see the quality of the seam, while saving time.

Benefits

The chameleon glasses are equipped with two sensors, which monitor the intensity of light and lightly switch the darkness of the glasses. The delay is half a second, in such a short time it is impossible to catch a "bunny". The principle of the action of rapid darkening of glasses works on the polarization of liquid crystals at a voltage. You can work in them at temperatures from -5 to +55 degrees. Advantages of chameleon glasses are as follows:

• Ease.
• There is no feeling of squeezing the face.
• Have ventilation, do not watery eyes.
• Provide a good overview.
• Glasses do not get fogged up.
• Tightly fit to the face.

Welding sunglasses are ideal for work in hard-to-reach, narrow places where the application of the mask is impossible.

Scope of use

Welding goggles as a means of individual protection, required at the request of safety rules, are applied when:

• Manual arc welding.
• Gas-oxygen welding.
• Work on the semiautomatic device.
• Work with a gas burner.

A wide range of products on the modern market gives the buyer the opportunity to choose the right product at affordable prices.

When buying glasses for work it is recommended to try them on the spot to pick up a copy with the best fit to the face. In shops at an affordable price you can buy good, comfortable welding glasses. The price of "chameleons" in comparison with conventional means of protection is higher, in Moscow they will cost about 2300 rubles, but the cost is compensated by their obvious merits.
