These consumables give low carbon pure nickel
with the addition of titanium for refinement and deoxidation.
They are used for joining pure nickel to
itself, for buffer layers, and for cladding joint faces and
flanges. The solid wire is also useful for welding cast
iron to give soft low strength deposit.
Applications include **tanks and vessels, process
pipework and heat exchangers**, in chemical plant for salt
production, chlorination and evaporation of caustic soda.
Also used for handling corrosive alkalis and halides. Temperature 150°C and no PWHT required.
Alloy type
Low carbon pure nickel weld metal with titanium
de-oxidation.
Microstructure
In the as-welded condition the microstructure
consists of almost pure nickel austenite. It is
strongly ferromagnetic at room temperature.
