Description:

Elgamatic 138 is a copper coated wire for use with the MIG/MAG process, which deposits a 2% Ni /

0.6% Mo / 0.3% Cr weld metal. It is intended for welding the very high tensile quenched and

tempered steels with a minimum yield strength of 900 MPa, such as Weldox 900, but is also suitable

for Weldox 960 when 5-10% undermatching is specified. Elgamatic 138 can be welded with either an

Ar/20% CO2 or CO2 gas shield, but the Ar mixture gives better fracture toughness at low temperature

and higher strength levels.
