Paying attention to CO2 arc welding process,
Daido Steel Co.,Ltd., has studied the deoxidizing theory
for a long time, under guidance of the late Dr.HARUJIRO SEKIGUCHI.
And, we developed the CO2 arc welding wire
and established the welding technology.
We started
the mass production of solid wire “DS1” in the year 1955.
Furthermore, Daido was the first to “DD” wire for Ar-CO2.
Recently, we succeeded in developing discriminated solid
wires, for instance,
the good slag detachability Wire,
the wire for galvanized steel, the ferritic stainless wire
for the exhaust gas disposal system, and titanium and
titanium alloy wire for GMAW. |
