OK 21.03 SMAW
Type
Description
OK 21.03 is designed for gouging, cutting and
piercing mild and alloyed steel, cast iron and
non-ferrous metals, with the exception of pure
copper, using standard welding equipment. The
electrode can be used in a wide variety of applications,
such as bevelling, the preparation of
cracked areas before welding and the back-gouging
of root runs.
Welding current
AC, DC- OCV 70 V
Procedure
The arc is struck with the electrode perpendicular
to the workpiece, after which the electrode is
pointed in the direction of travel at an angle of
about 15-20°C and pushed forward.
Gouging speed 100-150 cm/minute depending
on the depth of the groove. Deep grooves can be
made by repeated gouging. Welding can follow
without further preparation, but, when gouging in
stainless steel, a thin layer with increased carbon
content is obtained and it should be removed by
grinding.
When using OK 21.03 indoors, it is necessary to
have very good ventilation or fume extraction.
