Applications and Features :

• E81T1-Ni2 is designed for welding for 590N/mm2 grade steel with 100% CO2 gas.

• It provides superior impact properties at low temperature.

• It also provides stable arc, less spatters, smooth weld beads and good weldability.

• It can be used for single or multi-pass weld with semi-automatic and automatic welding.
