| Process type: SMAW |
|
For welding of 490N/mm2 high tensile steel.
|
|
Applications:
Shielded metal arc welding of mild and 490N/mm2 tensile steels in ships, bridges, buildings and pressure vessels. |
|
Characteristics on usage:
LB-52 is the most widely used low hydrogen type covered electrode for all-position welding of 490N/mm2 high tensile steel. 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 300-350ºC for 30-60 minutes before use. (2) Take the backstep method or strike the arc on a small steel plate prepared for this particular prpose to prevent blowholes at the arc starting. (3) Keep the arc short as possible. |
