Description

Seamless copper coated flux-cored wire for single- or multipass welding of carbon- and high strength steels, using M21 (Ar CO2) shielding gas or pure CO2. The weld deposit has excellent mechanical properties till -30°C in mix gas application. The main features of this wire are excellent weldability in all positions, excellent bead appearance, low amount of spatters and easy to remove slag. In position PF very high welding speeds are possible due to an optimized slag characteristic. Due to the seamless design of the wire: hydrogen pickup during operation and storage can be avoided; no porosity issues even on primer plates and very good feeding performance are achievable. The average hydrogen content of the pure weld metal is about 1-3 ml 100g weld metal.
