DESCRIPTION
CHM 08A can be used for copper-coated solid welding wire for submerged arc welding. Weld metal zone has excellent synthetic technological properties when corresponding welding flux is used. With a higher deposition efficiency, high quality and low intensity of labour, etc.

APPLICATION
The welding wires are used for welding important structures of low carbon structural steel and low alloy steel. Such as boilers, pressure vessels from chemical works and nuclear power station, bridges and ships, etc.

Sizes of wire: Diameter Φ(mm)2.0、2.5、3.2、4.0、5.0
