Characteristics and field of use
The nickel-base-flux-cored wire (NiCrMo) UTP AF 6222 Mo PW is suitable for joining and
surfacing on nickel-base materials of the same nature and on C- and CrNi-steels as well as
for cladding on C-steels, furthermore in high temperature applications.

UTP AF 6222 Mo PW distinguishes by a hot cracking resistant and tough weld metal. It is
suitable for operating temperatures up to 500 °C and above 800 °C. It must be noted that a
slight decrease in ductility will occur if prolonged heat treatment is given within the temperature
range 550 – 800 °C.
UTP AF 6222 Mo PW provides excellent positional welding. It has excellent welding properties
with a regular and fine drop transfer. The weld seam is finely rippled and the transition
from weld to base materials is regular and notch-free. The wide parameter range enables an
application on different wall thicknesses.
