In our country, welding operations need to be licensed, welders are the type of work that belongs to the access category, in the professional qualifications of skilled personnel, only five of the 81 types of work in the access category, welders are one of them, and the actual situation is that most of the industry practitioners are unlicensed operations. With the continuous standardization of technology and the relevant requirements of the industry, more and more people want to take a welding certificate, the advantage of the certificate is still very large, first of all, the salary of the certificate and the non-certificate are very different, often able to reach more than double or higher level. Therefore, the issue of short-term welder training has naturally become a concern for practitioners.
Welding as an industrial "tailor" is a very important means of processing in industrial production, the quality of welding plays a decisive role in the quality of the product, so, what is the future development of welding technology?
Industry outlook. With the development of production, welding is widely used in aerospace, aviation, nuclear industry, shipbuilding, construction and machinery manufacturing and other industrial sectors, in China's economic development, welding technology is an indispensable means of processing. After entering the 21st century, welding is an important part of the manufacturing industry, and the rapid development, so it has brought unprecedented development opportunities to the welding industry.
At present, China consumes 300 million tons of steel every year (about tons of welded structure), and needs about 750,000 welding machines, and the welding industry will continue to grow in the next 8 10 years.

Protection against occupational hazards in electric welding operations.
To sum up, there are many kinds of harmful factors in electric welding operations, and the harm is greater, therefore, in order to reduce the occupational hazards of electric welders, a series of effective prevention and control measures must be taken.
1. Improve welding technology, improve welding process and materials.
By improving the welding technology, the welding operation is mechanized, automated, and the person is isolated from the welding environment, so as to fundamentally eliminate the harm of electric welding operation to the human body. By improving the welding process, such as reasonably designing the structure of the welding container, and adopting the new process of single-sided welding and double-sided molding, the welder is avoided from welding in the container with extremely poor ventilation, so as to greatly improve the working conditions of the welder; Another example is the selection of CO with welding fumes ion charge in-situ suppression technology. Protecting the welding process can make 80 90 welding fumes be suppressed on the working surface, so as to purify the fumes and dust on the spot and reduce the pollution of welding fumes.
Since most of the hazards caused by electric welding are related to the composition of the electrode coating, it is also one of the effective measures to reduce the welding hazards by improving the electrode material and choosing non-toxic or low-toxicity welding electrodes.
2. Improve the ventilation of the workplace.
The ventilation mode can be divided into natural ventilation and mechanical ventilation, in which mechanical ventilation relies on the pressure generated by the fan to ventilate, and the dust removal and detoxification effect is better, so in the room with poor natural ventilation, when welding is carried out in the closed container, there must be mechanical ventilation measures.
3. Strengthen personal protective measures.
Strengthen personal protection to prevent the hazards of toxic gases and dust generated during welding. Workers must use corresponding protective glasses, masks, masks, gloves, wear white protective clothing, insulated shoes, never wear short-sleeved shirts or rolled up sleeves, and wear protective helmets with air supply performance if working in closed containers with poor ventilation conditions.
4. Strengthen labor protection publicity and education and on-site follow-up and monitoring.
Necessary occupational safety and health knowledge education should be carried out for welding workers, so as to improve their awareness of self-prevention and reduce the incidence of occupational diseases. At the same time, it is also necessary to strengthen the monitoring of dust and toxicity hazards in welding workplaces and the physical examination of welders, so as to find and solve problems in a timely manner.

Welders, can not avoid **, eye burns, to protect themselves**, under normal circumstances, if you burn your eyes in the welding work, serious day and night are tears, unable to sleep, can be said to be unbearable pain, I listened to the old-timers took out a little gold, welding burned eyes and **, as long as you wipe some breast milk, two days can be better. After testing, the milk powder at the first point also has this function.
Therefore, it is recommended that the workers who are engaged in welders should buy some milk powder and carry out eye and eye maintenance and protection.

Hydration is key, as you will be working in a warmer environment for a long time. LZ can imagine a round apple and a shriveled apple. The cells are actually like jellyfish, and they are only beautiful when they are replenished with water, otherwise they are pickled jellyfish.
The toner can be used daily. After washing your face, pat it on, and then lock in the moisture with a moisturizer like a lid to prevent it from evaporating and making it drier. However, if you use a toning blister paper mask, it will absorb better, and leave it on for 3 minutes after washing your face.
The recommended is the toner of the Silk Grass Family. More than 10 pieces of 500ml, cost-effective, every day to apply is not distressing. Paper film is everywhere and cheap.
Note: I don't know if LZ is a male or female, I have a girl's experience.
** is the most important way to hydrate. Seaweed** does not work well. Homemade ** is not recommended, because the nutrient particles are too large, ** are not absorbed, it is better to eat it directly.
Collagen** is anti-wrinkle. I don't have anything to recommend this, because I personally customize red wine all year round**, and occasionally follow the trend to defeat some samples, and other effects are not clear.
Serums are premium products and are so-called good value for money. There are various serums for whitening, and the cheaper one for hydration is hyaluronic acid, which is a bit like a gel, but it should be shrunk with moisturizer immediately after wiping.

When dry welding, you must wear all kinds of labor protection equipment, and do not expose any part of the ** to the light of electric welding.
Your face will be baked red, you will feel black, maybe you will be darker. By the next day, the face will itch and eventually molt.
When washing your face, don't use alkaline soap, keep it moist, and apply some moisturizer or sunscreen.
Watch out for the future!

.Prevents burns and fires from splashing metal.
2.Prevent the harm of arc light radiation to the human body.
3.Prevent poisoning by certain harmful gases.
4.When welding pressure vessels, it is necessary to prevent welding from occurring**.
5.When working at height, wear a safety belt and a helmet-type automatic photoelectric welding mask.
6.Take care to avoid electric shock accidents.
Manual arc welding can be divided into four categories: flat welding, vertical welding, horizontal welding and vertical welding according to the welding position. There are the following basic requirements in terms of safety technology for manual arc welding:
l.The shell and workbench of the welding machine must have good grounding.
2.The no-load voltage of the welding machine should be between 60 and 90V.
3.Welding equipment should use a power switch with electric safety and should be installed in a closed box.
4.The welder must be carefully inspected before use.
Whether the insulation of the primary and secondary conductors is complete and whether the wiring is well insulated.
5.When the welding equipment is connected to the power network, the human body should not touch the live part.
6.When welding indoors or in the open field, light barriers must be set up around it to prevent arc light from harming the eyes of workers.
7.Welders must be equipped with appropriate safety equipment such as self-darkening welding masks, dry canvas coveralls, gloves, rubber insulation, and head-mounted welding helmets.
8.The welding insulated cord shall not be less than 5m, and the cord shall not be placed on the body when welding, and the ground wire shall not be stepped on.
9.It is strictly forbidden to weld while lifting parts in the process of lifting parts.
10.After the welding is completed, the power switch should be opened in time.
The personal protective measures for welding operations are mainly personal protection for the head, face, eyes, ears, respiratory tract, hands, body, etc. It is mainly dustproof, anti-virus, anti-noise, anti-high-temperature radiation, anti-radioactivity, anti-mechanical trauma and dirt, etc. In addition to wearing general protective equipment (such as work clothes, gloves, glasses, masks, etc.) for welding operations, you can also wear automatic lightening head-mounted welding helmets (for welding operations in closed containers and special workplaces that are not easy to solve ventilation) for special work occasions to prevent smoke and dust hazards.
For emergency repair and welding operations in highly toxic places, isolated oxygen respirators can be worn to prevent the occurrence of acute occupational poisoning accidents.
In order to protect the welder's eyes from arc light, a mask with special protective lenses must be used during welding, and different types of filter lenses are selected according to the intensity of the welding current. At the same time, it is also necessary to consider the eyesight of the welder and the brightness of the welding working environment.
In order to prevent welders** from being injured by arcs, welders should wear light-colored or white canvas overalls. At the same time, the cuffs of the overalls should be tightly tied, the neckline should be buttoned, and the cuffs should not be exposed.
For welding assistants and other workers near the welding site who are injured by arc light, they should pay attention to cooperate with each other when working, and the auxiliary workers should wear filters with moderate color shades. In the multi-person operation or cross operation site engaged in electric welding operations, protective measures should be taken, and protective shields should be set up to prevent the eyes of welders and other workers from being punctured by electric lone light.
In addition, wash hands with running water and soap after touching thorium tungsten rods, and wash work clothes and gloves frequently. Wearing sound-isolating earmuffs or sound-proof earplugs to protect against noise hazards is an effective personal protective measure.
