Characteristics and field of use
The rutile coated stick electrode UTP 6824 LC is used for joining and surfacing of stainless
and heat resistant steels / cast steels as well as for dissimilar metal joints (heterogeneous
joints) and for buffer layers0n corrosion - or wear resistant claddings0n C-steels. The weld
deposit is scale resistant up to + 1000 °C.
The stick electrode is weldable in all positions except vertical-down. It is distinguished by a
stable arc, minimal spatter, and very good slag removal. The weld seam is regularly marked
and free of pores.

Welding instruction
Weld the stick electrode slightly inclined with a short arc. For claddings, the pre-heating
and interpass temperature should be adjusted according to the base material. Re-drying
2 hours at 120 – 200 °C.
