Washington Alloy Co. USA EM13K

Specifications AWS A5.17 Class EM13K Description USA EM13K is the submerged arc wire equivalent to USA 70S-3 CO2 wire, therefore many characteristics are similar. USA EM13K contains a higher level of silicon than other submerged arc wires making it suitable for high speed, single pass welding of dirty or rusty mild steel plates. The increased silicon content reduces porosity by deoxidizing the weld pool and provides excellent wetting action, straighter bead edges and easy slag removability. More common applications would include welding of ships and barges, automobile bodies, railcars, building and bridges.
