Descrição
Caraterísticas:
LFC-701 is a flux cored wire suitable for flat and horizontal position welding. With excellent stable arc, low spatter, good slag detachability and deposition rate. It has good porosity resistance for fillet welding of zinc-primer coated steels.
Aplicações:
It is widely used for shipbuilding, bridge construction, offshore structure and general fabrication.
Notas sobre a utilização:
1. Use DC(+) polarity.
2. Use CO₂ as shielding gas.
3. Proper preheat at range 50-150°C and maintain interpass temperature under 150°C.
