What are the dangers of welding, and is welding harmful to the body?

Welding hazards are divided into two categories: chemical hazards and physical hazards. The chemical harmful factors are mainly welding fumes and harmful gases, and the physical harmful factors are mainly arc radiation, high-frequency electromagnetic fields, radiation and noise.

The main hazards of welding are as follows:

1. Electrode arc welding of steel, carbon dioxide gas shielded welding.

As well as self-protection welding wire arc welding produces smoke and harmful gases, the main components of smoke are: iron, silicon, of which the main poison is fierce, the use of copper-plated welding wire gas shielded welding smoke and dust also exist in the poison copper, the use of bottom hydrogen electrode, the main poison in the smoke is fluorine;

2. The smoke and dust of the electrode arc contain a large amount of ferric oxide.

It is not very toxic and the particles are fine, about less than 5 microns, but prolonged exposure may form welding pneumoconiosis.

3. Toxic gases are mainly ozone and nitrogen oxides.

They are produced by the ultraviolet radiation of the arc acting on oxygen and nitrogen in the ambient air, the concentration of ozone is related to the welding material, shielding gas and welding process parameters;

4. Aluminum and aluminum alloy argon arc welding.

The toxic gases are mainly ozone and nitrogen oxides, and there are corresponding metal fumes in argon arc welding of other non-ferrous metals (such as copper, nickel, magnesium and their alloys, etc.);

5. The CO content is high when CO2 gas shielded welding arc starts, and attention should be paid when welding in a closed space, and ventilation measures are generally required. Generally speaking, the more smoke and dust, the weaker the arc radiation and the lower the toxic gas content, and conversely, the higher the arc radiation, the higher the toxic gas content;

6. Noise: The main harm to the human body is hearing loss, which can cause deafness in severe cases.

Harmful, radiation is severe. As the saying goes, dry welding is shameless, and dry welding is very harmful to the face.

Summary. Hello dear and happy to answer for you. The impact of welding on China is:

Welding affects the quality, reliability and life of the product, as well as the cost, efficiency and market response speed of production: China's steel output in 2002 exceeded 100 million tons, if you add imported steel, the total amount of steel circulating in the domestic market reached more than 200 million tons, becoming the world's largest steel producer and consumer. At present, steel is the main structural material in China, and steel will still occupy an important position in the next 20 years.

Kissing, welding, also known as welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many types of energy** in modern welding, including gas flames, arcs, lasers, electron beams, friction and ultrasonics. In addition to being used in factories, welding can also be performed in a variety of environments, such as in the field, underwater, and in space.

Welding can be dangerous to the operator wherever it is, so proper precautions must be taken when performing welding. The possible injuries caused by welding to the human body include burns, electric shock, visual impairment, inhalation of DU gas, excessive ultraviolet radiation, etc. Before the end of the 19th century, the only welding process was the forged welding of metal, which had been practiced by blacksmiths for hundreds of years.

Zui's early modern welding techniques appeared at the end of the 19th century, first with arc welding and oxy-gas welding, and later resistance welding.

One: metal soot.

Two: toxic gases.

Three: nitrogen oxides.

Four: arc radiation.

In fact, there are many harms to the body caused by electric welding, how to say about regular electric welding work, we should strengthen personal protective measures, strengthen the protection of personal ruler buckets, and prevent the harm of toxic gases and dust during welding. Wangling years of milling, thank you Que Pei!

How harmful is this kind of welding rod to the human body, you want to hide the harm of human beings is relatively scattered, easy to burn, and people are also easy to damage the eyes and eyes, and damage to various organs of the human body.

The harm of this kind of welding rod to the human body is quite great.

If it is absorbed directly, the consequences can be severe.

Buttons are very harmful to the human body, especially to the human eyes.
