UTP 2535 CoW
Basic coated stick electrode for high
temperature cast materials
Application field
UTP 2535 CoW is suitable for joining and surfacing high-temperature cast alloys of the same or of similar
nature, such e. g. G-X 50 NiCrCoW 35 25.
Main applications are centrifugal- and mould cast parts for reforming pyrolysis ovens. Working temperature
of the ovens: up to 1200° C / air.
Welding properties and special properties of the weld metal
UTP 2535 CoW has a stable arc, good slag removal and fine-rippled seam structure. The weld metal has
an excellent creep strength and a good resistance against carburization and oxidation.

Welding instruction
Clean welding area. Hold stick electrode as vertically as possible and with a short arc. Apply string beads
with little weaving. This stick electrode is weldable with low amperage settings. The interpass temperature
of 150° C should not be exceeded. Re-dry stick electrodes for 2 – 3 h / 250 – 300° C.
