Submerge Wire (LSW-EB3) and Flux (LSF-40) F8P2-EB3-B3

▶︎ Characteristics:

LSW-EB3 is a CrMo-alloyed low impurity wire electrode (suitability for step-cooling) for submerged arc welding of heat-resistant steels in boiler and pressure vessel construction as well as pipe manufacture.

 


 

▶︎ Applications:

It is suitable for welding of pipes and tubes of matching compositions in power plants, refineries, petrochemicals, fertilizers plants.

 


 

▶︎ Notes on Usage:

1. Dry the flux at 350℃ for 60 minutes before use
2. Not recommended to welding more than two passes.
