How to reduce the harm of tungsten pole to human body effectively?

Why is thorium tungsten, the most widely used electrode, so popular? Thorium tungsten electrode for argon arc welding tungsten needle has excellent comprehensive performance. Can withstand overload current; Long service life, oxidation resistance, not easy to deformation; Easy to start arc, continuous arc in the welding process, arc stability, not scattered arc. But I’m sure you’ve heard it before, Thorium tungsten is radioactive, and frequent use is bad for your health, Is that the case? Let’s listen Tungsten expert – North tungsten new material how to say? In fact, the radiation hazard of thorium and tungsten is small, the radiation dose is very small, and it has little effect on human body. But that doesn’t mean you can do whatever you want with thorium tungsten!! Because the tungsten needle is sharpened when the dust will be inhaled into the body, will cause internal irradiation, internal irradiation is still harmful to the human body. So how do you prevent this from happening? When using the new North Tungsten sharpening machine to polish the tungsten needle, the tungsten dust will be put into a sealed box, will not emit in the air, reduce the harm to the body!铜焊丝,Copper Welding Rods,铝焊丝,aluminium welding wire,镍焊条,Nickel electrode,药皮焊条,Flux Coated Brazing Welding Rods
