[MW:4617] uniform distrubution of austenite in ferrite matrix

Hi everyone,
I am having the WPS for the Duplex SS ( ASTM A 995 Gr.4A) The microstructure of weld shows the dendritic austenite in ferrite, HAZ and base metal shows nonuniform distribution of austenite in ferrite. The requirement is uniform distribution of austenite in ferrite matrix.
Can this pattern of microstructure cause adverse effect?

With Regards,
Rutvik
