What are the dangers of doing gas shielded welding to the body?

It is very damaging to the eyes and **, and inhaling more carbon dioxide for a long time will suffocate people or cause chest tightness and difficulty breathing.

Ultraviolet (UVR) and infrared (IFR) damage to the eyes and ** is an important aspect of occupational injuries in electric welding operations. The eye symptoms of welders are electro-optic ophthalmia, chronic blepharitis, conjunctivitis, lens opacity, etc., and the prevalence of chronic blepharitis and conjunctivitis tends to increase with the increase of working years.

The main damage from excessive UVR exposure is photosensitive keratitis, and welder cataracts are associated with infrared exposure. Recent studies abroad have shown that workers exposed to excessive UVR are at risk of developing non-melanocytic ** carcinoma and other chronic diseases such as ocular malignant melanoma.

Carbon dioxide is a colorless and odorless gas, and inhaling more carbon dioxide can suffocate people and feel chest tightness and difficulty breathing. To avoid inhaling more carbon dioxide, you should try not to squat near the carbon dioxide shielding weld, if you feel that you have difficulty breathing and chest tightness, you should immediately move away from the carbon dioxide protection weld to a ventilated place.

Extended information: Carbon dioxide gas shielded welding is one of the welding methods, which is a method of welding with carbon dioxide gas as the shielding gas. It is easy to operate in terms of application and is suitable for automatic welding and all-round welding.

There can be no wind during welding, which is suitable for indoor work. Gas shielded welding has high current density, strong arc light, high temperature, and produces high concentration of harmful gases under the action of high temperature arc and strong ultraviolet rays.

Be sure to wear a mask when welding, and try to stay away from the strong light and heat of electric welding. Maintain air circulation, etc.

The gas, dust and arc radiation produced by gas shielded welding are harmful to the human body, and silicosis will be produced by gas and dust inhalation, but ordinary people will not weld against smoke and dust when welding, and there is a mask, and the incidence of this aspect is very low.

The most harmful thing is that the lack of effective protection against radiation will burn**, but as long as you wear a thicker welder's suit, you will be fine, as long as you protect it properly and don't take your health seriously, it will be fine.

Hazards and Prevention of Welding Operations · Combustion accidents caused by welding sparks. Burns and scalds caused by welding flames or candles. Electric shock accidents and falling accidents that occur during the welding process.

Welders will cause lesions in the blood, eyes, lungs, etc. during the operation. The radiation hazards that welders are often exposed to in welding include strong light, infrared, ultraviolet rays, etc. The X-rays produced by the electron beam in welding can affect the health of the welder.

During the welding process, the welding parts, welding rods, dirt, paint, etc. of the metal evaporate or burn due to high temperature, forming smoke-like vapor dust, causing poisoning. The high-frequency electromagnetic fields generated in welding can make people dizzy and tired. The hazards of welding operations are not inevitable.

These hazards can be prevented as long as every welder strictly adheres to the safety regulations for welding and cutting operations. Safety precautions for the use of welding torches and cutting torches · The suction performance and air tightness must be checked before using the welding torch, and the connecting parts, gas energy channels and regulating valves of the welding torch shall not be stained with grease. When the torch is ignited, the acetylene valve should be opened first to ignite, and then the oxygen valve should be opened to adjust the flame; When turning off the fire, the acetylene should be turned off first, and then the oxygen.

When discontinued, it is strictly forbidden to permanently connect the welding torch, hose and air source. When using the cutting torch, the patent leather and rust layer on the working surface should be cleaned, and the work should not be carried out on the cement floor to prevent rust water and cement from splashing and injuring people in case of high temperature. When the torch is ignited, the ignition test should be done first to check whether the cutting nozzle is installed.

In the event of a ceasefire, acetylene should be turned off first, and then oxygen.

If possible, it's better not to do it.
