Application field
UTP A 34 N is used for MIG joining and surfacing on complex aluminium bronzes, particularly on such
with high Mn content and on steel and nodular cast iron. Due to its good seawater resistance and the general
corrosion resistance, this alloy is suitable in the ship building industry (propellers, pumps and armatures)
and in the chemical industry (valves, slides, pumps) on parts subject to chemical aggression in
combination with erosion. Surfacing on shafts, gliding surfaces, bearings and dies have proven, due to the excellent
friction coefficient, to be very suitable.
Welding properties and special properties of the weld metal
The weld of UTP A 34 N should be performed by applying pulsed MIG technique. The weld metal distinguishes
itself by high mechanical values. It is tough, pore-free and crack resistant. Machining is possible with
tungstene carbide tools. The weld is corrosion resistant and nonmagnetic.

Welding instruction
Clean welding area to metallic bright. Preheat larger workpieces to approx. 150° C. Keep heat input as low
as possible. Interpass temperature of 150° C should not be exceeded.
