It is a low-hydrogen type root pass electrode for high-tensile steel of grade 490N/mm²

Applicable Standards


Characteristics and Applications

• It is a low-hydrogen type root pass electrode for high-tensile steel of grade 490N/mm²
• Low-current welding results in a stable arc, aesthetically pleasing weld bead formation, and excellent back-side penetration
• Suitable for single-sided welding and double-sided forming welding for submarine pipeline docking

Welding Posture


Precautions of Use

• Grinding the joints before welding will improve the pass rate of radiographic testing.
• Please refer to the precautions for using welding electrodes
