Characteristics and field of use
UTP AF 155 is a high-efficiency flux cored wire with metal powder filling, for all position
welding with mixed gas M21 acc. to EN ISO 14175. It features outstanding mechanical
properties in temperature range down to – 40 °C with very low fume level and oxide build
up. The stable arc, the smooth droplet transfer, the secure penetration, its high deposition
rate in the spray arc range and the high deposition efficiency of 98 % approx. are only some
of the positive properties of this wire. It is characterized by almost spatter-free welding with
good wall wetting, flat and concave weld shape, radiographical soundness and porosity free
weld metal. It is suited for manual and mechanized welding for single and multilayers and
root pass welding is proven in all positions.
