AWS A5.17 F7A2-EL12 Mild Steel Submerged Arc welding flux, SAW flux
SJ301 is a kind of silicon-calcium-type sintered flux,mesh 10-40(2.0-0.45mm) and basicity
1.0. Either alternating or direct current can be used, but welding wires must be connected with
the positive electrode when direct current is used.The welding technology has good performance,
fine detachability and fine appearance of weld.
Usage:
The flux is fit for the submerge-arc welding of low-carbon steel and low-alloy steel,as well as
the fast single-way and double-surface welding of thin steel sheet.
Cautions:
1.The oil soil,moisture,iron and other foreign substances must be removed from the welding joint.
2.It is better to use direct current.
3.The welding flux must be baked under 300-350ºC for 2 hours.
