Thanks again MMA. I'll have a look at it shortlyHi Nick
If you look on my fluxcore thread I posted a pck of a fail that's highlighted by cut and etch budy
Thanks Munkul. From the photos it looks like MMA has cut the weld along its length and about half way through and then broken it. Am I reading that correctly?What he said. Cut a cross section and etch it, and do a nick break test like above also.
Thanks. I’ll get some of that stuff. Just had a look your post on cutting and etching, very interesting stuff and good stuff for the learning curveAll good we all learn somewhere!
At college we used Nital which is nitric acid and alcohol, but difficult to get hold of nitric acid though and its a bit nasty to deal with. Learned the trick of phosphoric acid plus heat off welding tips and tricks.
Thanks DanRust remover gel works too.
