AWS A5.23 F8A4-EG-G
▶︎ Characteristics:
LSW-EG-G For the welding of 550MPa weather-proof steels. It combines with LSF-68, for submerged arc welding application. Provides soft and stable arc, lessspatter, nice welding appearance, good slag removal, less fumes, excellent weldability. Presents good corrosion and anti-cracking resistance.
▶︎ Applications:
Its is suitable for a low temperaturaet -40℃ services, commonly used in railway and bridge constructions.
▶︎ Notes on Usage:
1. Dry the flux at 350℃ for 60 minutes before use
2. Not recommended to welding more than two passes.
