Can anyone tell me what wattage YAG I need to engrave a .025" deep by .025" wide line on the surface of a 1/4" thick piece of aluminum? CW, pulsed or Q-switched? I have a 30" x 30" X/Y flat bed setup with a CO2 in it now, but I find that using the Cermark solution for this application not as "permanent" as I would like for doing motorcycle parts. I really want to "ENGRAVE" the parts.
Thanks..
