Reducing headaches associated with slag on laser grating
Slag buildup does occur on copper grating, but it is also removed much more easily than slag that builds up on mild steel slats. When a metal fabricator processes thicker material on the laser cutting machine with copper slats, it can expect to see spatter from the cutting process, but it is far less than it would be if the laser had steel slats.Web
