Is gas welding harmful to oxygen and acetylene

The gas produced by the combustion of oxygen and acetylene is harmless, but the blue gas that reacts with the impurities in the iron plate when cutting the iron plate is harmful.

Carbon dioxide gas shielded welding produces the highest concentration of carbon monoxide. The welding arc is a strong light source that can produce medium and short-wave ultraviolet rays, which can cause electro-optic ophthalmia. As long as it is protected, it will generally not affect fertility. Reference.

Oxygen: a gas necessary for respiration, long-term breathing of pure oxygen, or high concentrations of gases may lead to accelerated aging, and in severe cases, it may lead to the natural (somewhat sensational) nature of the human body.

argon, inert gas, no obvious harm in contact; Nitrogen, which does not support respiration, is the most abundant gas in the atmosphere; Acetylene, a flammable and explosive gas, should have no toxic effect on the human body. However, if the concentration of these three gases is too high in the human body, it can lead to the risk of suffocation.

Harmful to the body.

Carbon dioxide gas shielded welding is far less harmful to the human body than other electric welding methods, but it is also necessary to do a good job of protective measures. A small amount of carbon dioxide is not harmful to people, and the relative molecular weight of carbon dioxide is 44 larger than the average relative molecular weight of air 29, so its density is also greater than that of air. 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, try not to squat near the carbon dioxide shielding weld, if you feel that you have difficulty breathing and chest tightness, you should immediately stay away from the carbon dioxide shielding weld and go to a ventilated place. When welding, you should be fully armed, wear welding protective clothing, foot and knee pads, and head coverings. Gas masks are indispensable, as well as noise-proof earplugs, so that the harm can be minimized.

1.As far as welding is concerned, the sparks generated during welding contain a large amount of ultraviolet rays, which can cause damage to the human body and damage the epidermis, but the damage to depth is rarely reported. Regardless of the soldering method (except for soldering on the radio), electric welding produces ultraviolet rays, which will cause certain damage to the human body.

2.The principle of carbon dioxide protection welding is because the temperature of the welding joint is too high, and the oxidation of the metal of the welding joint can be reduced by covering the solder joint with carbon dioxide (this welding method is often used for more valuable and precise welding), and no toxic substances are produced during the welding process, and there is a lot less oxide dust than conventional welding, which is more conducive to the health of welders than conventional welding.

There are harms of gas shielded welding.

First, soot 2 manganese poisoning 3 metal smoke fever 4 chronic pharyngitis.

Second gas 5 odor 6 nitrogen oxides 7 carbon monoxide 8 hydrogen fluoride 9 benzo third arc light 1 to the eye 2**.

Fourth, radioactive 3 noise.

Fifth, 4 electromagnetic fields.

Second, welding fumes are produced during welding, which is harmful to the human body, and there is the harm of arc light to the eyes, so attention should be paid to protection. Welding is a special type of work, and some commonly used welding methods have these hazards.

Welding fumes need to be protected, arc light needs to be protected, CO2 gas is heavier than air, and air circulation treatment is required for operation in narrow and confined spaces.

Comrade, the answer to this question is absolutely yes, the principle of gas shielded welding is to use gas around the arc to prevent the unfavorable factors in the air (such as H) from intervening in the melt droplets and forming cracks and other defects, here you are talking about carbon dioxide shielded welding is to use carbon dioxide as a gas to protect the molten iron (molten steel, etc.) droplets in the melt. What's in this process, let's take a look:

1. To play the arc, there must be ionization, high school physics has said, matter is composed of tiny particles such as atoms, electrons, etc., in fact, our arc is to ionize the neutral atoms of the gas after the process of reaching a certain frequency band of energy of the particles, forming an arc, the manifestation of energy is high temperature, the maximum temperature of carbon dioxide gas welding can reach more than 3000 degrees (this is not clear about the ha), this melting makes the molten iron droplets or the metal droplets of your welding consumables will evaporate, This means that there will be a high concentration of metal vapor around the welder, which is the reason for the bad smell, and long-term breathing of these metal particles will seriously affect the health of internal organs;

2. The arc light itself is very harmful, if you don't wear a mask, wear good clothes and long sleeves, etc., you won't have an obvious reaction at that time, but after a day or two, you will find that ** has been red and swollen, molting; If you accidentally look at the arc light for a few more minutes, then your eyes will definitely hurt at night;

3. There are other things that I can't remember for a while, I hope the above can basically answer your doubts!

No matter what kind of welding is harmful to the body, the light that appears during work will radiate, and the gas will have an effect on breathing and throat, but as long as the protective measures are appropriate, normal people should be able to resist it, and as for the problem of childbirth, it is better to ask someone who has come over...I don't think it affects fertility issues....My colleague's child is healthy...

Gas shielded welding is very harmful to the human body, for example: arc light can stab the eyes, close to the ** can be baked, the most important thing is that the lungs are extremely harmful, if the working environment is more closed, the shorter the onset of the disease, the long 6 to 8 years, the short 3 to five years can be onset, and the disease is not easy to treat, can only use drugs to control its development, and the upstairs said, it is harmful to men's reproductive function, it is recommended that there are no children, less contact with this thing,

CO2 gas shielded welding has two kinds of harm to the human body, one is gas, that is, the smoke and dust from welding, and the other is what people call arc light! It is very harmful to people's lungs and reproductive function. Try not to do it for men, and don't do it for too long if you want to do it.

It is best for women not to do it before giving birth, which will have certain problems for future babies!!
