AWS F6A4-EM12
Sintered Flux F6A4-EM12
Sintered Flux,AWS F6A4-EM12, is a special sintered flux for the purpose of the spiral welded pipe with fluorine alkali type. The alkalinity is 1.8. It is a light grey color circular particles and the size is 2 ~ 0.28mm (10 ~ 60 mesh). With excellent welding technological properties; it has high welding speed, stable arc, easy slag removal, beautiful weld appearance. Applying special process welding metallurgical reaction is extremely good, deposited metal is pure, and in low temperature toughness impact is higher. AC / DC both can be applied. Connect the wire to positive end while using DC.
