Etching a weld AA6056 (AA4xxx filler wire)
Etching a weld AA6056 (AA4xxx filler wire)
(OP)
I have a big problem with finding an etchant for this:
AA6056 welded together (laser welding, AA4xxx filler wire).
I've tried many solutions, but still can't reveal the microstructure of the weld.
Any tips? Anybody had to deal with something similar?

We always check after T4 and T6.
Hope this is of any help!

immerse in NaOH solution (12 g in 100 ml H2O) for ~ 10 s
rinse with H2O
immerse in HF solution (2 % HF by volume in H2O) for ~ 10 s
I have no information on how a 4XXX alloy filler metal would respond.
