説明
特徴
LSF-39 is an active flux. It is designed for butt or fillet welding on sheet metal with nice bead appearance, porosity resistance and good slag forming and removing and improved toughness. prevent porosity during welding. It is recommend for single pass welding steel plate under 25 mm thick.
アプリケーション
Typical applications include pressure vessels, H beam, pipe-mill application, shipbuilding, LPG Tank and general steel structure.
使用上の注意
1. Dry the flux at 350℃ for 60 minutes before use
2. Not recommended to welding more than two passes.
