It was just still a little hot from cutting when the acid was applied budy that's all.Why the different colours through the weldment? Root fusion (lack of) and throat too thick?
The way its etched it looks like corrosion.
Ah mate I did all those yesterday for a couple hours hotter looked good but didn't help. Manipulation was the key on the root in the end.Looks like classic flux core to me. It's brilliant stuff vertical up or for butt welds. Fillets I've always found it lacking penetration at the root. I've tried using less voltage, whacking the voltage right up, travelling faster, travelling slower, pulling at different angles.
Maybe I was just doing it wrong. Always looked very pretty,
Yes duel shield budyI'm guessing this is gas shielded?
Hi Jack no budy that was the lower part. 1st attempt on it.Definitely no penetration at the root but also very little on the right side of the fillet. Might be some undercut there as well.

Was that the "top" of the weld?
Thanks for posting that - interesting.

This is why you need to cut and etc jack it tells you where you messed up. Solved it all on 3rd attempt and moved on to mma v up and overhead fillet, it's been a whileHi Jack no budy that was the lower part. 1st attempt on it.
Exactly what I need to do. What is the etching fluid you're using?This is why you need to cut and etc jack it tells you where you messed up.
Thank you for putting the lines in budy I was trying to figure out how to but gave upDefinitely no penetration at the root but also very little on the right side of the fillet. Might be some undercut there as well.

Glad to helpThanks mate
I'm testing out on fillets and butt welds later in the wk so I'll try a take a few picks of the processes if I get a chance budyGlad to help
