DuriAuxiliary gas for Fiber Laser 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.Oxygen
Oxygen 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. Nitrogen
Nitrogen 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. Air
Air, 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 1 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 8573-1-2571 standard.

What to Look For When Buying an Air Compressor
An air compressor is a very useful tool that can help you complete many different types of construction jobs. This handy machine makes many tasks much easier, but not all of them are created equally. Understanding what to look for when buying an air compressor will help you make an informed decision. Here are some of the things you should look for. These include price, size, and energy efficiency. Also, make sure to consider the air compressor’s type.
Single-stage air compressors are quieter
When it comes to noise level, single-stage air compressors are the way to go. These machines have fewer moving parts and are quieter than two-stage models. Single-stage air compressors use an axial flow design and can be quieter than their dual-stage counterparts. Single-stage air compressors can run longer and at lower pressures. Single-stage air compressors can be used for light industrial applications. They have a long life expectancy, with some models lasting for over 3 thousand hours.
While some single-stage air compressors are quieter than two-stage air compressors, both models have noise-reduction features. One type features rubber parts, which are designed to dampen noise. Another feature makes a compressor quieter: its location near the job site. Some models feature rubber base plugs and rubber mats to reduce floor vibrations. In addition to using these features, single-stage compressors are easier to transport.
Noise levels are important when choosing an air compressor. Some machines are too noisy for comfortable work, and some businesses don’t want to expose customers to noise-generating air compressors. Other noise levels can even endanger workers’ health. Single-stage air compressors are more affordable than dual-stage compressors. They are also quieter and more powerful. But be prepared for the noise. Some single-stage air compressors are still noisy.
Compared to their two-stage counterparts, single-stage compressors are quieter when running at full capacity. However, double-stage compressors are quieter on low capacities than single-stage units. Those with variable speed are quietest at lower capacities. The difference is about 10db. If you’re concerned about the noise level, you should consider a two-stage air compressor. But if you have a small workshop, it may not be suitable for you.
One-stage air compressors are generally more efficient than two-stage air compressors. The noise from a two-stage air compressor is lower because there’s no intermediate stage. Single-stage air compressors also use a piston that rotates in a single stage, while dual-stage air compressors, also known as duplex models, are more efficient. A single-stage air compressor is quieter, but double-stage compressors are louder.
Two-stage air compressors are more energy efficient
Two-stage air compressors are more energy-efficient than single-stage machines. The efficiency of two-stage air compressors is increased through a combination of improved efficiency and increased longevity. These machines can store more air and have higher compression ratios. One model of a two-stage compressor can hold approximately 83 cubic feet of air at 100 PSI and 120 cubic feet at 150 PSI. A two-stage compressor is also quieter.
Two-stage air compressors are more energy-efficient because they have 2 pistons instead of one. These air compressors achieve a higher pressure rating and recover more quickly. This type of compressor is perfect for jobs that require high air pressure for a prolonged period of time. In addition, they can operate multiple tools simultaneously. This makes them better for commercial and industrial use. Listed below are some benefits of two-stage air compressors.
Single-stage air compressors can power tools in the garage or kitchen, but they are not as reliable for industrial applications. Single-stage compressors have larger parts that tend to experience condensation. Furthermore, single-stage compressors do not last long in continuous use and are less energy-efficient than two-stage ones. Whether you’re using the compressor for a single tradesperson, a small crew, or a large construction crew, two-stage compressors are the best choice.
Single-stage air compressors are often used in small-scale food preparation and production. Single-stage air compressors are easy to transport between locations, and can be plugged into several electrical outlets. Single-stage compressors are also ideal for high-volume food processing. A dual-stage air compressor is ideal for industrial use. In some cases, you can even move the single-stage air compressor between two-stage air compressors.
Single-stage compressors often cycle too quickly, drawing more electricity than two-stage units. A variable speed unit stays on a low speed for hours at a time. Single-stage air conditioners force you to lower your thermostat settings while single-stage air conditioners run too often. Both units are energy-efficient but they are not as energy-efficient as variable-speed compressors. The main difference is that single-stage air conditioners tend to drain the power source quicker.
Piston-driven air compressors are quieter
A piston-driven air compressor is 1 of the quietest types of air compressors. It is less noisy than reciprocating air compressors. A piston-driven air compressor can reach 62 decibels, while a scroll compressor is around half that volume. The 2 main components of a scroll air compressor are the piston and the helical screw. These air compressors are both very efficient and quiet.
Older compressors are incredibly noisy. They produce a “wumpa” noise similar to a large engine. They are also capable of producing a high-pitched whine. These noises can be deafening, especially in a small workshop. That’s why it’s essential to look for a quiet compressor. But what makes a compressor quiet? Read on to learn more about this essential tool.
Another difference between piston-driven air compressors and electric-driven air compressors is the power source. Electric air compressors produce less noise than gas-powered compressors, which use an engine. Piston-driven air compressors are also more efficient. They also generate less heat, making them an ideal choice for offices and other settings where noise is a problem. The best way to decide between the 2 types of air compressors is to check the manufacturer’s warranty and read the ‘Description’.
Noise reduction is the first priority of a compressor’s owner, so make sure that you have the right model. If you’re working on something sensitive, don’t place the compressor too close to a building where people might be nearby. Noise can be very disruptive to the workspace and can cause health problems. To help combat noise, you’ll need to buy a quiet air compressor. And don’t forget to consider its location: Piston-driven air compressors are quieter than their reciprocating counterparts.
Piston-driven air compressors are quiet because the piston is made of thin metal and more rubber, which absorbs the sound. Unlike reciprocating air compressors, piston-driven air compressors are more efficient than their dual-piston cousins, which are quieter and more powerful. So which type is right for you? Take a look at some of the main differences between the two. If you want a quiet compressor, make sure it meets the specifications required by the job you’re working on.
Oil-lubricated air compressors are more cost-effective
There are several reasons why oil-lubricated air compressors are more expensive than dry-type air compressors. First of all, oil-lubricated air compressors tend to be more reliable and quiet. Additionally, oil-lubricated air compressors require fewer parts and can last longer than dry-type air compressors. These are just a few of the many benefits of using oil-lubricated air compressors.
Oil-free air compressors have some disadvantages. They are less durable and may not be as efficient as oil-lubricated models. Additionally, because oil-lubricated air compressors use oil, they can get very noisy. While they are less expensive, they are not the best option for heavy-duty work. However, modern oil-free air compressors have soundproofing and are suitable for industrial use.
When purchasing an oil-lubricated air compressor, make sure to choose 1 with a tank capacity that meets your needs and your space. Larger tanks can be more expensive than small tanks, but larger units are easier to move around. Also, be sure to consider the weight and size of the portable air compressors when making your choice. If the weight is too large, you may have trouble carrying it from place to place.
Another benefit of using oil-lubricated air compressors is their reduced need for oil. These models can last up to a decade longer than oil-free counterparts. Oil-free air compressors are more affordable and can achieve the same high performance as their oil-lubricated counterparts. Many industrial applications benefit from these air compressors. So, which 1 is right for you? We’ve listed a few of them below.
Another benefit of choosing an oil-lubricated air compressor is the reduced cost of maintenance. This type is more durable than its oil-lubricated counterparts, which require regular oil changes to keep them running smoothly. However, it is not feasible to transport an oil-lubricated compressor, which means that you must install it permanently to keep it working efficiently. In addition, these air compressors are difficult to move and are not portable, which can limit your ability to use it in a pinch.
