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.
