▶︎ Characteristics:
LSF-56 is a neutral flux. It is designed for butt or fillet submerged arc welding in combination with LSW-EH14.With nice bead appearance, good porosity resistance and good slag removability.
▶︎ Applications:
Typical applications include pressure vessels, shipbuilding, boilers and general steel structure.
▶︎ Notes on Usage:
1. Dry the flux at 350℃ for 60 minutes before use.
2. Not recommended to welding more than two passes.
