Applications
Fillet welding of 50 kgf/mm2 class tensile strength steel constructing ships, bridges, buildings and other structures.
Characteristics
- Iron powder low hydrogen type electrode designed for welding 50 kgf/mm2 class tensile strength steels. An extremely small amount of hydrogen in the deposited metal ensures good mechanical properties.
- a large quantity of iron powder in the covering ensures high efficiency.
- stable, arc, smooth bead appearance and easy-to-remove slag; usability particularly outstanding in horizontal fillet welding.
- improved operational efficiency can be expected through combined use of long electrodes and gravity welding equipment.
Precautions
- dry before use at 300-350°C for approximately 60 minutes/
- pits or blowholes may occur with welds in excessively primer-coated steel plates
- The ideal ration of electrode length consumed to bead length deposited is between 1:1.2 and 1:1.4.
