Welding of zirconium tube
Zirconium is a kind of high melting point metal, which is light gray. Its density is 6.49 g / cubic centimeter. Melting point is 1852 + - 2.001 degrees, boiling point is 4377 degrees Celsius.
The surface of zirconium is easy to form a layer of oxide film, which is shiny, so the appearance of zirconium is similar with steel. Zirconium has corrosion resistance, which is soluble in hydrofluoric acid and aqua regia, when it is at high temperature, it can react with non-metallic elements and many metal elements, generating solid solution compounds. Zirconium is easy to absorb hydrogen, nitrogen and oxygen, with the increase of temperature, the reaction is strong, so zirconium welding protection requirements are particularly at high the welding time, the argon purity must be guaranteed more than 99.999%. When it is welding, it should use small current, faster welding and cooling speed.
Zhengzhou Sanhui welding master who has more than 30 years of welding experience and perfect welding technology, is the first choice of zirconium tube (zirconium) welding.
