UTP 694
Basic coated stick electrode for wear
resistant surfacings on hot working
tools
Application field
UTP 694 is suited for hot wear resistant buildups on hot working tools, subject mainly to friction and
compression, e. g. hot cutting knives, edges on forging tools, roll mandrils, axial rollers, die cast moulds,
where high-alloy hot working steels, such as e.g. 1.2344, 1.2365, 1.2581, 1.2567 are used. Due to the excellent
metal-to-metal gliding properties also suitable for buildups on guiding and gliding surfaces, such as hammer
tracks.
Welding properties and special properties of the weld metal
UTP 694 has a good weldability except in vertical-down welding, has good temperature resistance and a
quiet arc and a good slag removal. Good chip removal machinable with carbide tools.
Hardness of the pure weld metal : approx. 45 HRC

Welding instruction
Clean welding area carefully and preheat workpiece to 400° C. Hold stick electrode as vertically as possible
and with a short arc. Preheating temperature should be maintained during the whole welding operation.
Subsequent slow cooling. Re-dry stick electrodes that have got damp for 2 h / 300° C.
Current type DC (+)
