CO2 gas shielded welding wire consists of flux cored wire and solid wire, but whether a hydrogen wire?
No. CO2 shielded welding solid welding wire uses CO2 gas as gas phase protection, and the gas cored wire, slag phase double protection or separate slag phase protection can be used in the flux cored wire.
Low hydrogen welding wire is in flux cored wire according to a classification based on the different hydrogen content of the flux cored wire according to how much the content of diffusible hydrogen in deposited metal, divided into ultra low hydrogen H 5ml/100g (chromatography), low hydrogen (hydrogen content between 5~10ml/100g and H > ml/100g) high hydrogen. The lower the H content of the deposited metal, the better the crack resistance.
