Characteristics and field of use
UTP UP 6222 Mo and the flux UTP UP FX 6222 Mo are applied for joint welding of base materials
with the same or with a similar composition, e. g. Alloy 625 (UNS N06625) or NiCr22Mo9Nb,
Material-No. 2.4856 or mixed combinations with stainless steels and carbon steels. Furthermore the
wire-flux combination is used for cold-tough Ni-steels, e. g. X8Ni9 for LNG projects.
UTP UP 6222 Mo / UTP UP FX 6222 Mo is also applied0n alloyed or unalloyed steels for cladding
of corrosion resistant plants.

Operating data
Polarity = ±
The welding area has to be free from impurities (oil, paint, markings
etc.). Welding must be performed with a low heat bbbbb. The maximum
interpass temperature is at 150° C. Flux has to be re-dried prior
to welding: 2 hours at 300 - 400° C.
Flux height: approx. 25 mm
Stick out: approx. 25 mm
