(OP)
I need to etch API 5L X65 pipe that is lined with Inconell Clad 825 that has been GTAW/FCAW welded with ERNiCrMo3 filler material for Vickers Hardness and CVN testing of the weld metal and fusion line. Any suggestions?
Thanks.
Thanks.

The Ni based filler should have enough higher resistance to be identifiable.
In the lab I would use electrolytic etch, lots of options but probably something stronger than oxalic.
