PW.SJ604 is a type of agglomerated flux with fluorine and alkaline,PWSJ604 provides goods weld bead appearance and exvellent slag removal.With high purity of weld bead metal.high impact toughness performance in low temperature and low diffusible hydrogen content in weld bead metal.


Working with proper welding wires (ENi1,EM12K,EA2,EA3 etc.) can weld the structures made of low-temperature steel and high strength steel such as ocean pressure vessel;

Deap ocean oil pipe lines,and other ocean project,the flux working with proper wires can perform very well in the situation that requires mid-speed welding on the thin steel plates.
