UTP 34 N anti-wear & anti-corrosion
Classifications basic coated complex aluminiumbronze stick electrode
DIN 8555 EN 14700 AWS A5.13
E 31-UM-200-CN E Cu1 E CuMnNiAl
Characteristics and field of use
UTP 34 N is suitable for joinings and surfacings on copper-aluminium alloys, specially with
high Mn-content as well as for claddings on cast iron materials and steel. Main application
fields are in the shipbuildung (propeller, pumps, armatures) and in the chemical industry.
The good friction coefficient permits claddings on shafts, bearings, stamps, drawing tools
and all kind of gliding surface.
UTP 34 N has excellent welding properties, spatterfree welding, good slag removal. The
weld deposit has high mechanical values, a good corrosion resistance in oxidizing media,
best gliding properties and a very good machinability. Crack resistant and pore-free.

Welding instruction
Clean welding area thoroughly. Pre-heating of thick-walled parts to 150 – 250 °C. Hold electrode
as vertically as possible and weld with slight weaving. Weld with dry stick electrodes
only! Re-drying: 2 – 3 hours at 150 °C.
