Laser Oxide Removal

Laser oxide removal is easier to automate than other technologies.

Laser oxide removal.

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. Oxide layers as well as anodized layers absorb the laser light particularly well and can be evaporated very effectively. The oxides adhere poorly to the metal when painted which then causes paint to chip and flake. 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. Even at the speed at which laser cutting machines operate harrison said the oxide removal equipment can keep up. Since laser systems have no moving parts they require very low maintenance. Because of its efficiency it is being used in an increasing number of applications.

Laser oxide scale removal. Oxides are instantly vaporized and ejected from the target surface by very small burst of plasma produced by the pulsed laser beam and so exposed a clean oxide free surface. Oxide layers absorb laser light particularly well and thus can be vaporized and removed very effectively. The plasma generated during evaporation simultaneously tears away the transparent layers which are located above the oxide layer on the material resulting in an active completely contamination free.

Harrison added that typically one of the laser operators in the cell has time to send parts through the machine avoiding potential bottlenecks. 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. Removal of oxide layers. And unlike mechanical and electrochemical cleaning lasers function without consumables.

It takes about 20 or 30 seconds for a part to process through the machine. Utilization of oxygen as an assist gas causes an exothermic reaction that creates. Laser oxide removal before welding and several other surface treatments metal surfaces must be clean and without oxides. In fact many inline solutions already exist.

When aimed at a metal surface the dirt layer and any oxides underneath will absorb th. Remove rust easily from metals using a 1000 watt laser. Fiber laser cleaning systems can remove. As a result they are very well suited for automation and can.

As laser and plasma cutting are much more cost effective than die cutting it is quickly becoming the norm for part.
