Characteristics and field of use
UTP 80 Ni is suited for joining and surfacing0n commercial pure nickel grades, including
LC nickel, nickel alloys and nickel-clad steels. These materials are employed primarily in
the construction of pressure vessels and apparatus in the chemical industry, in the food
industry and for power generation, where good behaviour under corrosion and temperature
is demanded.
UTP 80 Ni is weldable in all positions, except vertical-down, and gives smooth, notch-free
seams.

Welding instruction
Weld with dry stick electrodes0nly! Prior to welding the stick electrodes must be dried
2 – 3 hours at 250 – 300 °C. Clean the weld zone thoroughly. The V angle of the seam
should not be less than 70°. Weld with short arc, avoiding weaving as much as possible.
