Etching 303 to 430F Weldment, GTAW
(OP)
We have autogenously welded these two metals. I want to evaluate the weld interface, penetration and HAZ. My question is what chemical etchants do I use?? I have heard Aqua regia, HNO3 and Alcohol or a mixture of HNO3-HCl and H20? Which one or other would work the best?
