Flux Cored Wires


ArcStar 81N1M AWS A5.29 E81T1-Ni1M

Characteristics and Applications: ArcStar 81N1M is a gas-shielded flux cored wire for all-position welding. It is designed for welding 590 N/mm2 high tensile steel for low temperatures. It provides good weldability with smooth bead appearance, less spatter and stable arc as well as good impact properties down to -40 . It is also suitable for welding on construction machinery, shipbuilding, offshore, structures, bridges, storage tanks and piping.

Notes on Usage: 1. When the heat input is excessive, the impact value tends to be reduced. Therefore, perform welding with selecting proper heat input depending on the required impact value. 2. Preheating at 50~150 is required depending on steels, plate thickness and restraint. 3. Use DC(+) polarity. 4. Use 75~80%Ar+25~20%CO2 as shielding gas.

AWS A5.29 E81T1-Ni2C EN 758 T 46 4 2Ni P C1 H10

Characteristics and Applications: TWE-811Ni2 is a titania type flux-cored wire for all-position MAG welding. It provides good weldability with smooth bead appearance, less spatter and stable arc as well as good impact properties down to -40 . It is suitable for welding of 590 N/mm2 high tensile strength steel on construction machinery, structures, bridges, storage tanks and piping.

Notes on usage: 1. Pre-heating at 50~150 is required depending on steels, plate thickness and restraint. 2. Mechanical properties tend to be reduced when heat input is over 35J/cm. Therefore, perform welding with lower welding current and heat input. 3. Maintain inter-pass temperature under 150 in multi-pass welding to keep excellent mechanical properties. Use 99.8% or higher purity of CO2 Gas. 4. Use DC(+) polarity. 5. Keep dry during storage and delivery.
