Description 
Semi-Basic, agglomerated flux for welding of essential structural steel in combination with appropriate SAW wire (such as EH*4,EA2, EM*2K etc.). Weld bead hardly increases Si and Mn, it belongs to metallurgy neutral. It has perfect welding performance, stable arc, good surface, excellent slag removal, high impact toughness at low temperature. The filler metal should be connected to Positive when DC.
application
SJ**1 can be used for many applications ranging from boilers to pressure vessel, pipeline and low alloy steel structure.
