Shielded metal arc welding of mild and
490N/mm² high tensile steels of ships, bridges,
buildings and pressure vessels. For welding of
490N/mm² high tensile steel.
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
Dry the electrodes at 300-350°C for 30-60 minutes before use.
Take the back step method or strike the arc on a small steel plate prepared for this particular
purpose to prevent blowholes at the arc starting.
Keep the arc as short as possible.
