UTP A 8036 S nickel alloys
Classifications TIG rod
Special alloy
Characteristics and field of use
UTP A 8036 S is an alloy of the same composition as the base material and used for welding
cast alloys with a nickel content of 34 – 40 % (INVAR qualities). The special operational
area is the structural welding of housings made of plate and cast pieces with a nickel
content of 36 %. Application field: air plane construction.
The weld metal contains high mechanical properties and a very low expansion coefficient.

Welding instruction
Thorough cleaning of welding area is essential. Welding parameters need to be adjusted to
each individual application. Pay attention to a low heat input. The weld should be performed
by applying a pulsed technique.
