Conforming to: AWS-A5.17 F6AO-EL12 F7AO-EM12K DIN BSC 198AC10SKM
Description and application
Versatile flux for welding of ordinary structural steel and boiler steel in combination with appropriate SAW wire(such as EM12, EM12K and EL8), which can obtain smooth weld bead with flat weld interfaces free from undercut.Steadily arc and easy slag removal, no phenomenon of slag-flow are other special features of LJ-SJ301. It can be applied to the Multi-pass weld and multi-wire weld, especially to weld pipelines in various diameters.
