Cutting, did you get the right one?The schematic diagram of laser
cutting is shown in the following.During the process, auxiliary gas
is necessary to blow off the slag/dross in the kerf and cool down
the cutting surface, also it protects lens and nozzle of laser.
Basically there are 3 kinds of gas: Oxygen, Nitrogen and Air, any
of them affects directly to the cutting performance, speed,
thickness etc. So we really need to think better before
action.1.OxygenOxygen is commonly used to cut thick carbon steel
because the chemical reaction between iron element and oxygen helps
the metal absorb heat and promotes it melt, which can greatly
improve the cutting efficiency.However, oxygen will cause a marked
oxide film on the cut surface and it will have a quenching effect
around, increases the hardness which impact on subsequent
processing. It also turns kerf to black or dark yellow.Generally,
Oxygen assists carbon steel plates cut, low-pressure punching, and
low-pressure cutting. Oxygen is generally vaporized from liquid
oxygen which provided by the local supplier, so the quality of the
gas source is clean and no need special treatment.2.
NitrogenNitrogen will form around the molten metal as protective
atmosphere while it's assisting the cut, prevent oxidation of
the material, avoid the formation of oxide film. However, the
cutting speed is not as fast as oxygen, and the nitrogen
consumption of the nitrogen is large which means the cost will be
higher.The non-oxidized surface has the characteristics of
direct welding, strong corrosion resistance and the kerf turns
white.Generally, nitrogen is used to cut stainless steel,
galvanized sheet, aluminum, aluminum alloy, brass and other
materials, by low-pressure perforation and high-pressure cutting.
When cutting with nitrogen, the change of the gas flow has a great
impact on the cutting performance, in this case, make sure the gas
flow is sufficient and constant. Nitrogen is usually vaporized from
liquid nitrogen provided by supplier, so the quality should be
clean.3. AirAir, as it's the most economic medium because it's much
easier to obtain than oxygen and nitrogen, nobody can charge you
for air! Every one knows the air contains about 20% oxygen and
about 78% nitrogen, so it can make up for both shortage and cutting
speed is slower than oxygen but faster than nitrogen. Since the
oxygen is involved, the kerf turns a little bit yellow. It's the
most economic option for you as long as you are okay with the color
change.Generally compressed air can be used for cutting sheet-metal
parts, aluminum sheet, nonmetal and galvanized sheet etc., air
assist can certainly reduce the oxide film and absolutely save your
cost, therefore, air assist is more and more equipped in fiber
laser cut industry.Compressed air can be obtained easily with an
air compressor, but not any air compressor can be equipped for
Fiber Laser Cutter as the Air itself is not clean, especially after
compressing, there are plenty of water, oil and particles and any
of them sprayed on the lens, the transmission of laser beam will be
seriously affected and focus scattered, resulting bad cutting
effect such as bottom burrs or rough kerf, even
obsolescence.Situation could be much worse if it is high-power
fiber laser, even a tiny particle or a little spray will very
possibly burn your entire lens cone.In order to make the most
economic (Air assist) way workable, ensure cutting quality and
avoid any damage for your fiber laser, the compressed air must be
pure and constant, 100% meet ISO 8573-1-2010 standard.Dehaha
4-in-one (Compressor + receiver tank+ dryer + filters) high
pressure air compressor is special compressor for Fiber Laser
Cutting industry, custom built to provide filtered, dried,
continuous reliable supply of high pressure compressed air at
2~10ºCdew point to assist laser cutting. Produce your own assist
air at a fraction of the cost of cylinder.Product
