What gas welding flux cored wire?
Flux cored wire must be welded with carbon dioxide, because flux cored wire is divided into four types: self protection, gas protection, gas self protection and other forms of protection. The self shielded welding wire is protected by the chemical reaction of the powder at high temperature to produce gas and slag, and this type of welding wire can be welded without additional protective gas.Flux cored wire is not equal to the combined gas and slag protection, does not apply to the field or windy conditions. However, the flux cored wire for welding pool melting than solid wire. Because solid wire components often encounter the phenomenon of uneven, resulting in stomatal flux cored wire. But this phenomenon does not exist. Stomatal probability is reduced. Other theories on the cored wire is better than the mechanical properties of weld solid wire. But the flux cored wire manufacturer quality uneven in quality by using flux cored wire, need to take more risk.Flux cored wire production is to reduce the cost and not caused by the chemical composition of welding wire is mainly silicon manganese content fluctuation. So whenever possible. Do not use flux cored wire
Flux cored wire is formed by cold drawn after the steel strip contains deoxidizer, arc stabilizing agent and other component powder. It is also called tubular welding wire. Usually under the protection of carbon dioxide gas or argon + carbon dioxide gas, and there is no need for gas protection, also known as self-protection.
