In order to effectively remove this recast a gentle electropolish is necessary.
Removing oxidation from laser cut steel.
As the use of thermal cutting processes in the metalworking industry has increased substantially the need to remove the oxidation produced by those processes has also increased.
Mix 1 quart of white vinegar with 1 quart of water in a bucket.
Laser cleaning is the best solution to remove oxide from aluminum.
Figure 3d shows a stainless steel part that has been electropolished after laser drilling.
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.
Laser oxide scale removal.
Oxygen is excellent for cutting mild steel as it actually speeds up the cutting process and allows cutting.
The cleaned parts clearly show the melted recast material around the cut and no gentle cleaning will remove this.
As laser and plasma cutting are much more cost effective than die cutting it is quickly becoming the norm for part.
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.
Ox 15 liquid descaler.
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.
Step 3 apply a quarter size amount of fine cut automotive rubbing compound designed for use on aluminum onto a terry cloth rag.
Removing the oxidised edge after laser cutting.
The oxygen causes an exothermic reaction that creates heat which helps the laser cut through the metal.
Stainless steel oxide removal.
Manually finishing these parts he adds is quite difficult because of high labor costs inconsistent practices and odd shapes that are not easily manipulated.

For example oxide can be removed before welding to strengthen the welds.
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.
Use the sponge to rub away any light oxidation from the surface of your aluminum coated furniture.
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.
Fabricators typically use oxygen as an assist gas during laser cutting of mild steel.
