Characteristics and field of use
UTP AF 68 MoLC PW is a strip alloyed flux cored wire with a rutile slag characteristic for
position welding of austenitic CrNiMo steels. The support provided by the fast-hardening
slag allows out-ofposition welding with high current magnitudes and high welding speeds.
The fine droplet, low-spatter, very powerfully welding spray arc, the reliable fusion penetration,
the self-releasing slag and the effectively wetting seam formation result in a high weld
quality at the same time as short welding times. Additional advantages to its application
result from the ease of handling, the low heat input due to the high welding speed, and the
small amounts of cleaning and pickling required. UTP AF 68 MoLC PW is preferred for flat
and horizontal welding positions (PA, PB). The weld metal is cryogenic down to – 120 °C and
resists intergranular corrosion up to + 400 °C.

Welding instruction
Welding with conventional MAG devices, slightly trailing torch position (angle of incidence
about 80 °), slight weaving of the torch is recommended in all positions. With 100 % CO2
the voltage must be raised by 2 V. The gas quantity should be 15 – 18 l/min.
