Dilution Calculation
A plate of 9% Ni steel is welded with a welding wire of composition 80%Ni-20%Cr. What is the approximate composition of the final weld if there is 40% dilution?
The plate contributes 40% and the welding wire 50% of the final composition
9% plate 0.4x9=3.6 0.4x91=36.4
Filler 0.6x80=48 0.6x20=12
