説明
特徴
LSF-56 is a neutral flux. It is designed for multi-pass groove welds. With nice bead appearance, porosity resistance and good slag removability. High welding efficiency, good toughness can be obtained. It produces good impact property and minimum 500N/mm² tensile strength when used with LSW-EM12K.
アプリケーション
Typical applications include pressure vessels, shipbuilding and general steel structure.
使用上の注意
- Dry the flux at 350°C for 60 minutes before use.
- When performing first pass welding, it is recommend to use lower current to prevent cracking.
