Characteristics and field of use
UTP 32 is a basic-coated tin-bronze stick electrode for joining and surfacing on copper tin
alloys with 6 – 8 % Sn, copper-tin alloys and for weld claddings on cast iron materials and
on steel.
UTP 320 is easy weldable and the slag removal is also easy. The corrosion resistance is
corresponding to identical or similar base metals. Seawater resistant. Very good gliding
properties.

Welding instruction
Clean welding area thoroughly. Ignite stick electrode inclined with scratch start. For wall
thickness of > 8 mm a preheating of 100 – 250 °C is necessary. Hold stick electrode vertically
and weave slightly. Use only dry stick electrodes. Re-drying 2 – 3 h at 150 °C.
