OK Autrod 19.30 GMAW
ERCuSi-A
Description
A continuous, solid, copper wire for the GMA joining
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 nonalloyed
steels and cast iron. Pulsed GMA is
recommended. OK Autrod 19.30 is normally welded
with pure Ar as the shielding gas; however, for
GMA brazing, the addition of 1% O2 improves the
brazing properties.
