Characteristics and field of use
UTP 65 D has been developed to satisfy the highest requirements for joining and surfacing.
It is extremely crack-resistant when joining steels of difficult weldability, such as . hard
manganese steels, tool steels, spring steels, high speed steels as well as dissimilar bl
joints. Due to the good corrosion and abrasion resistance and high tensile strength
UTP 65 D finds its application particularly in repair and maintenance of machine and drive
components, such as gears, cams, shafts, hot cuts, hot trim plates and dies. Also ideally
suited as an elastic cushioning layer for very hard surfacings.
UTP 65 D has outstanding welding properties. Stable arc, spatterfree. The finely rippled
seam has a homogeneous structure, very good slag removal, self-lifting0n parts. Good
weldability in awkward bs. Stainless, creep resistant and workhardening.
Hardness of the pure weld bl: approx. 260 HB

Welding instruction
Clean the welding zone thoroughly. Prepare X-, V- or U-groove0n thickwalled workpieces
with an angle of 60 - 80°. Preheat high-C-containing steels and solid workpieces to appr.
250 °C. Keep stick electrode vertical and weld with a short arc, use ber beads or slight
weaving, as applicable. Re-dry stick electrodes that have got damp for 2 h / 120 – 200 °C.
