Em12k Classification Essay

General Description

AS EM12K is copper coated submerged arc welding wire designed particularly for welding of mild steels. It contains higher Si than
AS S2 submerged arc welding wire.

It is used for submerged arc welding of unalloyed structural steels with a tensile strength up to 520 N/mm², ship's plates and fine grained carbon-manganese steels.
