Is welder harmful to health?

It must be harmful! The outcome of reproductive toxicity is of great significance, so in recent 10 years, some studies on reproductive toxicity of electric welding have been carried out at home and abroad, mainly involving the semen quality of male workers, reproductive outcome of female workers and injury mechanism. The research shows that the menstrual flow, shortened cycle, prolonged menstrual period, increased leucorrhea, spontaneous abortion, premature delivery and dysmenorrhea of female welders are higher than those of the control group [18]. The semen appearance of male workers with manganese poisoning is even grayish white, and the PH value is normal. The average liquefaction time was longer than that of the control group. The results showed that the average ejaculation volume, total sperm count, sperm survival rate and activity rate of male workers with manganese poisoning were lower than those of the control group, and the sperm abnormality rate of male workers with manganese poisoning was significantly higher than that of the control group [19]. It is considered that manganese metal can affect the spermatogenic system of male workers, have a direct toxic effect on sperm development, and can kill sperm, thus causing changes in male semen quality. It has also been reported abroad that the sex hormone secretion of welders has changed and the sperm quality has decreased, but it has no effect on the sex ratio of offspring. Welders are often exposed to strong light, infrared rays, ultraviolet rays, etc. X-rays produced by electron beam in welding will affect the health of welders. \x0d\ Harm of welding safety and prevention of combustion and explosion accidents caused by \ x0d \ welding sparks. \ x0d \ Burn and scald accidents caused by welding flame or candle. \ x0d \ Electric shock accident and falling accident occurred during welding. \ x0d \ welders will cause pathological changes in blood, eyes, skin and lungs during operation. \ x0d \ Welders are often exposed to strong light, infrared rays and ultraviolet rays during welding. X-rays produced by electron beam in welding will affect the health of welders. \ x0d \ During welding, due to high temperature, metal, covered electrode, dirt, paint, etc. Evaporation or combustion, forming smoky steam dust, causing poisoning. \ x0d \ The high-frequency electromagnetic field generated by welding will make people dizzy and tired. \x0d\ The danger of welding operation is not inevitable. These hazards can be prevented as long as each welder strictly abides by the safety regulations of welding and cutting operations. \x0d\ Safety precautions for using welding torch and cutting torch \ x0d \ \ When using welding torch, the air suction performance and air tightness must be checked first, and the connecting parts, air passage and regulating valve of welding torch must not be stained with grease. \ x0d \ ... When the welding torch is ignited, the acetylene valve should be opened first, and then the oxygen valve should be opened to adjust the flame; When turning off the fire, acetylene should be turned off first, then oxygen. When stopping use, it is forbidden to permanently connect the welding torch, hose and air source. \ x0d \ When using the cutting torch, the paint and rust layer on the working face should be cleaned, and it is not allowed to work on the cement floor, so as to avoid splashing rust-proof water and cement at high temperature. \ x0d \ ... When the torch is ignited, an ignition test should be conducted first to check whether the cutting nozzle is installed. When flameout, acetylene should be turned off first, then oxygen.
