Classification: F7A0-EM12K; F6A2-EL12
LJ-SJ501 is defined as a kind of aluminate rutile acid agglomerated flux, for welding of ordinary carbon manganese, low alloy structures and boiler quality steel and pressure vessel etc. in combination with appropriate SAW wire (such as EL8,EM12, EM12K). The flux suitable for high speed welding and provides very good weld bead appearance and excellent slag removal even with small angle preparation and fillet welds. The chemical nature of LJ-SJ501 provides high resistance to cracking. Additional features are resistance to porosity when welding rusty plate and low sensitivity towards arc below. Especially being applied to double-side with single pass weld and fillet welds.
