The advantages of welding include short production cycle, flexible structural design, reasonable materials, and the ability to assemble small parts into large ones, so it has been widely used in industrial production. However, during the welding process, many harmful factors are generated, such as metal fumes, toxic gases, high-frequency electromagnetic fields, radiation, arc radiation, and noise. So, during welding, welding operators need to have protective measures. There are many things that need protection during the welding process. Mainly includes dust prevention, noise prevention, gas prevention, high temperature radiation prevention, radiation prevention, mechanical injury prevention, etc. When welding, welding operators need to wear work clothes, gloves, glasses, masks, etc. In special circumstances, some may also need to wear ventilated welding caps. In situations where toxic gases are generated, equipment should be complete, and it is best to wear isolated oxygen respirators to reduce the possibility of poisoning. During the welding process, strong light is often generated, and a slight mistake can easily harm the eyes of the workers. Once injured, this kind of injury may be difficult to reverse. So, during the welding process, it is necessary to wear different filter lenses according to the intensity of light. The sound during the welding process is very harsh. Welders working in this environment for a long time can cause significant damage to their hearing. Therefore, during welding, welders should also wear ear protectors to reduce noise and protect their hearing. During welding operations, it is best for welders to wear specially designed clothing and not expose too much skin to the air. In addition to external factors, there is another very important factor, which is the welder's own technical problems. With superb skills and compliance with operating standards, the corresponding work quality will be greatly improved, while the danger will be correspondingly reduced.
