LB-52 is the most popular electrode for 490MPa class high tensile steel in ships, bridges, buildings

and pressure vessels. This electrode was adopted in the first nuclear reactor vessel of Japan. Its usability is good in all positions and it deposits weld metal of high quality.

Workability

• In all positions the workability is good and both fluidity and removability of slag are fine

• the arc is stable and bead appearance is auite beautiful.

Outstanding features of LB-52

The outstanding features of LB-52 among other E7016 electrodes

are:

• Excellent usability in out of position welding: better arc

concentration, easier slag removal, smoother bead appearance.

• Excellent mechanical properties: constant tensile strength, higher impact value.

• Excellent X ray soundness
