    I can't do it for a day without a mask, and I said it was a year.

    CO2 shielded welding, even if you don't protect for a day, it will be harmful to the body. If the welder does not have proper respiratory protection, it is easy to lead to welder pneumoconiosis. It is one of the twelve types of statutory pneumoconiosis.

    For nowPneumoconiosisNot medical**.

    Pneumoconiosis is a disease caused by inhalation of a large amount of dust that causes fibrosis of lung tissues, and there are also various complications such as hypoxemia.

    Therefore, it is not a matter of how many days it takes to get pneumoconiosis, but the degree of injury is different and the reaction is different.

    As a result of these inflammations, the patient and his family are in great distress. Be sure to do a good job of respiratory protection.

    1. It is recommended to choose N95 and N100 dust masks certified by GB2626-2006 standards according to the environmental dust concentration and hazards.

    2. It is recommended to choose a half mask made of silicone. It is more comfortable than other materials.

    3. It is recommended to choose a numbered mask. The size is good for a tight fit with the face and prevents dust leakage.

    4. It is recommended to choose a mask with low breathing resistance, and some masks adopt a double-piece, double-sided design, with low breathing resistance.

    5. For occupational protection, it is not recommended to advertise disposable masks. It is mainly a disposable mask, which is rarely divided into large and small sizes, and has the characteristics of simple structure, strong discomfort and uneconomical use of the face.

    6. According to the national standard, half of the face has the ability to cover the mouth, nose and mouth, nose and jaw.

    2 types, the second one is larger, more comfortable to wear, and has low facial pressure.

    At present, the N100 level masks, due to the principle of electrostatic adsorption of the filter cotton, are aware of the protection rate of ultra-fine dust, and the breathing resistance is only about 120 Pa, which does not affect the operation, and the cost is about one yuan per day. Due to the intensity of publicity, it is not widely known.

    Therefore, many people still recognize gauze masks and uncertified masks, but in fact, the money is not saved, and the health is also lost, which is very not worth it. The common masks with good quality in China are 3M, Baoshun'an, Mei Si'an, etc.

    It's possible in two or three years.

    In the process of electric welding, a lot of welding fumes will be generated, the particle size of electric welding fumes is very fine, the penetration is extremely strong, the protective effect of ordinary dust masks is very poor, it is easy to be inhaled into the lungs, causing damage to the lungs, and finally developing into electric welding mixed pneumoconiosis.

    Working in a dusty environment, it is recommended to do a good job of respiratory protection for your health. Choose a dust mask scientifically, choose a good mask with good protective effect, smooth breathing, and economical use. Helps prevent lung damage from occurring.

    The way to clean the dust: now masks must implement the GB2626-2006 standard. The grades of dust masks are divided into three grades: KN100, KN95, and KN90.

    Among them, KN100 can achieve nearly 100% (more) protection effect against ultrafine dust. If the granularity is large, KN95 grade can be selected.

    The protective effect of dust masks depends on 2 aspects. One is the filtration efficiency of the filter cotton. The second is how tightly the mask is combined with the face.

    Therefore, masks must be divided into large and small sizes, and the fit effect of masks and faces varies from person to person.

    The way to clean dust: the scientific selection of dust masks certified by GB2626-2006 standards can help prevent lung damage.

    1. Choose a duplex half mask type. Disposable masks are not suitable for long-term or occupational protection due to their high air leakage rate.

    2. Choose KN100 dustproof filter cotton for use. A low rate of protection will lead to physical injury.

    3. It is more comfortable to choose silicone material. It is suitable for long-term wear and is not easy to cause allergic reactions. Masks with high rigidity are prone to facial indentation.

    4. Masks are divided into large and small sizes, which is extremely important. Don't buy masks that are called generic models. Prone to air leakage.

    5. There are two types of masks that cover the mouth and nose, covering the mouth, nose and chin, and it is recommended to use the latter, which is relatively comfortable.

    6. It is recommended to choose a breathing mask. Some masks are designed with double filters, and the filters are double-sided, so that the masks are relatively easy to breathe.

    At present, there are KN100 grade products in China, and the comprehensive use cost is about one yuan per day.

    Summary. Hello dear, glad to answer for you! There is two shielded welding, the full name of two-shielded welding is carbon dioxide gas shielded welding, which is a kind of arc welding, which uses CO2 as a shielding gas to achieve high-efficiency welding, referred to as CO2 welding and two-shielded welding, also known as gas shielded welding.

    The composition of the second welding machine is mainly composed of welding power supply, carbon dioxide cylinder, wire feeder and welding gun. Second, welding is a kind of MIG/MAG welding, in which an arc is formed between the wire as an electrode and the weldment (connected to another electrode), and the high-temperature molten wire and the weldment form a molten pool by the arc to achieve the effect of connecting the weld.

The size of the welding current mainly depends on the welding form and speed of the wire feeding, the faster the wire feeding, the greater the welding current. The arc voltage needs to use the formula when the short circuit transitions: U i (L is the current symbol) 16 plus or minus 2 (volts) to calculate, in this case, the welding current is generally below 200A; When the current is more than 200A, the arc voltage is used by the formula: >>>More
