Description
Characteristics:
LSW-EB2 is a weld metal possesses good high temperature properties and meets radiographic quality. Copper coated 1.25Cr-0.5Mo solid wire for submerged arc welding. These wires are suitable for welding of creep resistance and similar composition high strength steels.
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.
