Hi guys,
I'm new here, so be gentle
Most of my steel comes from the scrap bin at the place where my dad works wh do laser cutting. They mostly have the steel with millscale on it, (I presume it's millscale, it's that hard as nails coating like a bluey colour) and of course the edges being laser cut are also very hard.
Any tips for removing this? I have been doing a lot of tig welding lately and this coating is driving me nuts as it blobs onto the tungsten and ruins it. I also find it very hard to get a "nice" tig bead with the scale still on.
I have tried sanding it off with 36, 60, 80 and 100 grit sanding pads and although they get it off, it's a laborious job and kills pads very quickly.
Is there anything I can brush on it and clean it off like a pickling paste but readily available?
what about one of those hobby grade sand blasters?
I would be interested to hear your solutions,
Cheers,
Simon
