Submerged Arc Welding Flux sj101G
SJ101G
Specification: EN760 SAFB 155 AC H5
AWS A.5.17/5.23 F7A2-EM12K F7A4-EH14 F7A6-EG-G F8A2-EA2-A2
Applications:
Single and multi-layer welding of steel for low temperature service used in offshore structures, chemical vessels, APl pipes, windmils and low temperature service equipments.
Characteristics: SJ101Gis an agglomerated fluoride-basic type flux
Metallurgical behavior:
The behavior of silicon and manganese is neutral, so it is better to weld with wires containing relatively high manganese and silicon.
Basicity: 3.1(BIIW)
Damp flux should be re-dried at 300- 350 °C for 2 hours. Rust, grease and moisture on the weldment should be removed before welding.
