For example oxide can be removed before welding to strengthen the welds.
Removing oxidation from laser cut steel.
Figure 3d shows a stainless steel part that has been electropolished after laser drilling.
Carbon oxide is formed on the edges of parts when gas is introduced during the thermal metal cutting process.
It can also be removed before several surface treatments such as before a coating process to prevent the paint from peeling off.
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.
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.
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.
As laser and plasma cutting are much more cost effective than die cutting it is quickly becoming the norm for part.
For manufacturers this can really result in a part of poor quality.
By gf lasers aug 17 2017 blog.
In order to effectively remove this recast a gentle electropolish is necessary.
Stainless steel oxide removal.
Use the sponge to rub away any light oxidation from the surface of your aluminum coated furniture.
Laser oxide scale removal.
The oxygen causes an exothermic reaction that creates heat which helps the laser cut through the metal.
This oxidation or scale left over from thermal cutting can cause problems for metal finishers and end customers alike.
Manually finishing these parts he adds is quite difficult because of high labor costs inconsistent practices and odd shapes that are not easily manipulated.
Utilization of oxygen as an assist gas causes an exothermic reaction that creates heat which helps the laser cut through the metal faster.
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.
Removing the oxidised edge after laser cutting.
The oxides adhere poorly to the metal when painted which then causes paint to chip and flake.
Mix 1 quart of white vinegar with 1 quart of water in a bucket.
Fabricators typically use oxygen as an assist gas during laser cutting of mild steel.
In addition not as much pressure is required to feed the oxygen to the cutting head.
