What is the harm of welding copper brazing the harm to people
Purple copper plate is better, mainly yellow copper bar, the burning of zinc is relatively serious, the body is not really good. Of course, branch to minimize smoke in the welding process, good ventilation and air exhaust, electrostatic dust is a good way of welding wire with no source sweep loss Wei special brass argon arc welding wire can be Odin
Brazing in the welding process, the heating body is welded, when the temperature reaches 600 degrees when the need to add borax powder surface scavenger, at this time in the borax powder oxyacetylene flame melt blowing part in the air, in the welding process with a small amount of copper vapor floating in the air, if workers will be properly protected, inhalation of borax the powder particles and the copper vapor, the body will accumulate heavy metals and compounds if things go on like this for boron, lung, liver, kidney and other organs damage, so the operator should strengthen the protection work and strengthen the ventilation in the workplace, in order to protect the health of.
Copper welding when the flux of inhalation in the lungs caused by the impact of copper will be heated with the air generated by oxidation, CuO, it enters the human body will become copper ions, it will cause heavy metal poisoning. So, wear a mask when welding, and if you do the industry, you must keep ventilation in the work area and avoid inhaling these poisonous gases.
