What gas will be produced when welding with wire and argon?
Mainly smoke and dust, other pollutants are currently inconvenient to deal with
First, argon gas is used as a protective gas, while tungsten inert gas arc welding is an inert gas flux cored wire.Argon is inert gas and does not participate in reactions.In general, argon gas is produced by welding metal gas.Tin content in welding wires should be especially small, so tin containing waste gas must not be called.At the same time, in the formulation of the welding wire, it seems that the organic matter is rarely added. There are mainly rutile, magnesia, iron powder and so on. Most of them are minerals, so they can not be written as organic waste gas.I personally feel that organic compounds are carbon and oxygen compounds. So, at three thousand or four thousand degrees of arc, should the gas go out CO2 and water?.The harmful gases produced by arc welding should be mainly ozone, nitrogen oxides, carbon monoxide, phosgene, hydrogen fluoride and so on.
Argon arc welding wire without coating, no metal powder, logically speaking, exhaust only water vapor and carbon dioxide, but the steel and welding materials are not one hundred percent pure, no matter how smelting are containing impurities. The temperature of the arc is very high, 9000-10000K, so some parent materials and many impurities are volatilized by steam.
