Hi,
Does anyone have any info to engrave on a shell casing. I have a basic and the current settings are not even scratching the surface of the be\rass casing.
Thanks
You can’t. A 40/45W CO2 laser can’t touch metal.
You can mark it using a metal marking spray like laserbond or cermark.

agreed. 40/45 watts is definitely not enough. in ads i have seen phone backs engraved so i see why the op thinks it should work
Those are anodized or have similar coating, which can be vaporized by the beam.

yeah, exactly.
Paint it first then laser off the paint. Either that or some form of metal marking product.
Thanks for the info, I had engraved a 20mm anti aircraft round, but it had green apparently paint or anodized finish. I may try painting the casing on a larger shell and see what happens.
