LC-300

LC-300 is the most widely used low hydrogen type covered electrode for all positionwelding of 50kgf/mm2 class high tensile strength steels.X-ray soundness and mechanical properties of the weld metal are excellent. The usabilitiessuch as arc smoothness, slag removal and bead appearance are good.

Applications Welding of 50kgf/mm2 class high tensile strength steels ships, bridges, buildings and
pressure vessels.
Characteristics LC-300 is the most widely used low hydrogen type covered electrode for all position
welding of 50kgf/mm2 class high tensile strength steels.
X-ray soundness and mechanical properties of the weld metal are excellent. The usabilities
such as arc smoothness, slag removal and bead appearance are good.
Notes on usage (1) Dry the electrodes at 300~350℃ for 30~60 minutes before use.
(2) Adopt the backstep method or strike the arc on a small steel plate prepared for this
particular purpose to prevent blowholes at the arc starting.
(3) Keep the arc as short as possible.
