Laser cut oxide removal.

Acid pickling is the use of an acid to dissolve either the oxide scale or a thin layer of steel under the scale allowing the scale to fall off. Manually finishing these parts he adds is quite difficult because of high labor costs inconsistent practices and odd shapes that are not easily manipulated. Using the laser s micron precision oxide can be removed in controlled layers and from predefined areas. Laser oxide removal can be used to remove those contaminants without introducing impurities in the base metal.

Fiber laser cleaning systemscan remove oxides from ferrous and non ferrous metals alike. Otherwise adhesion failure customer complaints and warranty claims will result â said tom fabek vp sales marketing. 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. Harrison added that typically one of the laser operators in the cell has time to send parts through the machine avoiding potential bottlenecks.

It takes about 20 or 30 seconds for a part to process through the machine. Metal oxide removal can be automated through cleverly built laser cleaning machines. Oxide removal laser oxide scale removal as laser and plasma cutting are much more cost effective than die cutting it is quickly becoming the norm for part. The second method which is preferred is acid pickling.

Even at the speed at which laser cutting machines operate harrison said the oxide removal equipment can keep up. Mechanical methods of scale removal are also not effective on intricate cuts which is one of the reasons to use a laser in the first place. Removal of oxide layers oxide layers as well as anodized layers absorb the laser light particularly well and can be evaporated very effectively. This oxidation or scale left over from thermal cutting can cause problems for metal finishers and end customers alike.

Therefore its removal is necessary before painting. The oxides adhere poorly to the metal when painted which then causes paint to chip and flake.
