DIN 8555
E 6 - UM - 60
Application / Properties:
Thick basic-covered
electrode for depositing
tough and wear resistant
overlays on components
subject to severe wear The
weld metal is crack-free and
without porosity and
resistant to impact and
shocks. It can be machined
only by grinding.
A tough buffer layer (with
1803 J electrodes) is only
required with very crack
sensitive steels. It is
possible to deposit a large
number of layers without the
need of intermediate buffer
layers to prevent cracking.
Suitable for:
Excavator parts, bucket
edges, bucket teethes,
drilling 1 bits, coal
planes, conveyor screws,
polygon edges, crusher jaws
and cones.
