EN ISO 17632-A-T 46 4 2Ni P C 1 H10

Characteristics and Application

AWS A5.29 E81T1-Ni2C  is a titania type flux-cored arc welding 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. Use DC(+) polarity
2. Must pre-heating at 50—150℃ varied on steels, plate thickness and restraint.

3. Mechanical properties might fall when heat input is over 35J/cm. Therefore, perform welding with lower welding current and heat input.

4. Maintain inter-pass temperature under 150℃ in multi-pass welding to keep excellent mechanical properties. Use 99.8% or higher purity of Co2 Gas.

5.Keep the product dry, while it is stored or delivered.
