Stainless steel oxide removal.
Removing oxidation from laser cut steel.
Fabricators typically use oxygen as an assist gas during laser cutting of mild steel.
Oxygen is excellent for cutting mild steel as it actually speeds up the cutting process and allows cutting.
Rodger talbert writes in his book paint technology handbook that sanding grinding chipping and blasting are effective means of removing the oxide layer from laser cut parts.
Ox 15 liquid descaler.
Use the sponge to rub away any light oxidation from the surface of your aluminum coated furniture.
Carbon oxide is formed on the edges of parts when gas is introduced during the thermal metal cutting process.
The oxides adhere poorly to the metal when painted which then causes paint to chip and flake.
In order to effectively remove this recast a gentle electropolish is necessary.
Anyone who cuts steel parts with a co2 laser and uses oxygen as an assist gas is familiar with the strip also known as laser oxide that forms as a result of the process around the contour of the cut.
Laser assist gases are used at the point where the laser cuts the metal and most laser cutting companies use either oxygen or nitrogen as the assist gas.
It can also be removed before several surface treatments such as before a coating process to prevent the paint from peeling off.

As laser and plasma cutting are much more cost effective than die cutting it is quickly becoming the norm for part.
Step 3 apply a quarter size amount of fine cut automotive rubbing compound designed for use on aluminum onto a terry cloth rag.
Laser oxide scale removal.
Laser cleaning is the best solution to remove oxide from aluminum.
For example oxide can be removed before welding to strengthen the welds.
Mix 1 quart of white vinegar with 1 quart of water in a bucket.
Removing the oxidised edge after laser cutting.
In addition not as much pressure is required to feed the oxygen to the cutting head.
This oxidation or scale left over from thermal cutting can cause problems for metal finishers and end customers alike.
Figure 3d shows a stainless steel part that has been electropolished after laser drilling.
The cleaned parts clearly show the melted recast material around the cut and no gentle cleaning will remove this.
The oxygen causes an exothermic reaction that creates heat which helps the laser cut through the metal.
Utilization of oxygen as an assist gas causes an exothermic reaction that creates heat which helps the laser cut through the metal faster.
