A continuous, solid, copper wire for the GMA join-ing of copper-zinc alloys and
low-alloyed copper and for the GMA brazing of zinc-coated steel sheets.
OK Autrod 19.30 is alloyed with silicon and manganese and has good flow properties and wear resistance.
The alloy is widely used in the joining of zinc-coated steel sheets in car body production,
as well as for overlay welding on low- and non-alloyed steels and cast iron.
Pulsed GMA is recommended. OK Autrod 19.30 is normally weld-ed with pure Ar as the
shielding gas; however, for GMA brazing, the addition of 1% O2 improves the brazing properties.
