A solution of nitric acid and alcohol, Nital, is used for etching of metals to reveal the microstructure. ISO 14104 is one of the standards detailing this well known procedure.

Some new pictures of etching. A-36 steel with 4 passes of 1/8" E7018-1. First pass was 84amps, second pass was 112 amps, third and fourth passes were 134 amps. My technique and amperage must have been lacking, as you can see from the pictures there is not a lot of penetration.
