OK Flux 10.62 SAW
Type High-basic EN 760: SA FB 1 55 AC H5
Description
OK Flux 10.62 is an all-mineral, non-alloying,
high-basic flux. The weld metal can be fully controlled
through the suitable choice of wires, independently
of the welding parameters. It is
therefore very suitable for the multi-run welding
of thick materials using the single-wire and multiple-
wire technique. OK Flux 10.62 is designed for
the multi-pass butt welding of mild, medium and
high tensile steels, as well as low-alloyed steels,
with an impact strength down to -40°/-60°C. As it
is a flux of the high-basic type, OK Flux 10.62
has a high current-carrying capacity on both AC
and DC. To increase productivity with no loss of
mechanical properties, OK Flux 10.62 is best
used together with iron powder addition. OK Flux
10.62 is especially suitable for narrow gap welding,
due to the good slag detachability and
smooth side-wall blending. Pressure vessels for
nuclear applications and offshore constructions
in which good CTOD values are required are two
areas in which OK Flux 10.62 can be successfully
used. It operates optimally at the lower end
of the voltage range.
OK Flux 10.62 yields low-oxygen weld metal
(approx. 300 ppm) and produces low-hydrogen
weld metal (lower than 5 ml/100 g).
