5/2/2012 · in a work by gare and hazeldean [43] on kinetics of decarburization of fe–c drops with slag, a similar lull period has been observed. in this case, one possible mechanism for the reaction stoppage may be the time required for diffusion of oxygen into the drop that will lead to formation of co bubbles and expansion of the drop.
the topic is not how to remove mill scale from structural steel, even though by last count there is ~ 10 million tons of it produced every year and about 1 million tons of it recycled into new steel. maybe a mig arc spray with pulse is the correct procedure for welding through mill scale comprised of many different forms of fe oxides that are quite hard, really do not know.

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.
