서브머지 와이어(LSW-EM12K) 및 플럭스(LSF56) F7A2-EM12K

설명

특성:

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.

애플리케이션:

Typical applications include pressure vessels, shipbuilding and general steel structure.

사용 시 참고 사항:

1. Dry the flux at 350°C for 60 minutes before use.
2. When performing first pass welding, it is recommend to use lower current to prevent cracking.
