Description

Versatile flux for welding of ordinary structural steel and boiler steel maching with suitable SAW wire (such as EM12, EM12K and EL8), which can obtain smooth weld bead with flat weld interfaces free from undercut. Stable arc and good slag detachability, from shot slag in welding, no phenomenon of slag-flow are other special features of HFX-SJ301. It can be used to the single pass weld and multi-wire weld, especially to weld pipelines in various diameters.
