What harm does carbon dioxide gas shielded welding do to the body?

Gas, dust and arc radiation produced by gas shielded welding are harmful to human body. Inhaling gas and dust can produce silicosis, but most people will not face smoke when welding, and there are masks, so the incidence rate is very low.

The most harmful thing is that radiation without effective protection will burn the skin, but as long as you wear a thicker welder's suit, you will be fine. As long as you protect yourself, you will be fine.

Many welders can live to be eighty or ninety years old after retirement. We'll be fine when the protection is in place.
