Flux cored wire is divided into the seam and seamless flux cored wire: seamless flux cored wire can be copper plated; Electrical conductivity of the moisture resistant wire custody process as well as the welding process are seam flux cored wire.
Flux cored welding wire features:
Welding wire should be stocked in dry environment. Open the packs just when welding, so as to avoid the wire rust.
Before welding please clean out the oil, rust, water etc from the welding surface.
Adopting CO2 gas shielding welding, and gas purity of CO2 is 99.98%.
The flow of gas CO2 should be controlled in the range of 20-25L/min during the welding process.
The extend length of the welding wire should be controlled in the range of 15-25mm.
Preheating before welding to 150-300 ℃, PWHT 700-740 ℃ tempered.
