It is a low hydrogen electrode, while the “-A1” indicates the presence of 0.5% Molybdenum in the weld deposit.
The electrode’s coating is designed to resist moisture absorption, which is crucial for preventing hydrogen cracking in the weld and ensuring weld quality.
The addition of 0.5% Molybdenum makes the weld metal suitable for high-temperature service and provides good creep strength and mechanical properties after heat treatment.
It offers a stable arc, smooth bead profile, and excellent slag removal, making it easy to use in all welding positions.
Widely used in the construction and repair of boilers, storage vessels.
