| Process type: SMAW |
|
For welding of 490N/mm2 high tensile steel.
|
|
Applications:
Shielded metal arc welding of mild and 490N/mm2 high tensile steels of ships, bridges, buildings and pressure vessels. |
|
Characteristics on usage:
LB-52-18 is an iron powder low hydrogen type covered electrode for all-position welding. The mechanical properties of the weld metal are the same as LB-52. Its. Usability by direct current is the best among low hydrogen type electrodes. |
|
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 purpose to prevent blowholes at the arc starting. (3) Keep the arc as short as possible. |
