Different material fiber laser cutting

Different material fiber laser cutting.

As we know,fiber laser cutting machine is more and more popular.There are many careers need the fiber laser cutter.

The higher cutting speed,save time.The smooth cutting effect,save huam source.The lower consumption,save cost.

Its the trend in many field to use it.

Fiber laser cutting machines enter into our lives from the industrial field, and more and more materials for cutting.

First, stainless steel cutting.

The stainless steel metal plate is generally cut with nitrogen to prevent oxidation. No burr edge, and can weld directly without post-treatment. According to the characteristics of the stainless steel material.Accelerate the fluidity of the liquid,and the cutting efficiency is higher and faster. The effect of cutting with oxygen may be worse than that of nitrogen.Like blackening and unevenness of the end faces.

Second, carbon steel cutting.

When laser cutting carbon steel, oxygen is generally use to obtain better results.While the oxygen reaction heat is to increase the cutting efficiency, the resulting oxide film also increases the beam spectral absorption factor of the reflective material. When using oxygen processing, there is a problem that the edge may be slightly oxidize. If a more demanding user can use nitrogen for high pressure cutting.It is also possible to achieve better cutting results by applying oil to the surface of the workpiece.

Third, aluminum cutting.

Aluminum is a highly reflective material in metallic materials.It has high reflectivity and thermal conductivity.In recent years, many manufacturers‘ laser cutting machines equipe with „anti-reflection devices“ to adapt to aluminum cutting,and laser cutting opportunities without „anti-reflection devices“ damage their optical components. At the same time, depending on the power of the equipment, the thickness of the cut aluminum material is also different. Generally, the thickness of stainless steel and carbon steel cut by the same equipment is thickerthan that of high-reflection materials such as aluminum. Aluminum is also more suitable for cutting with nitrogen, and the cutting effect is good.

Fourth, copper and brass cutting.

Like aluminum, copper and brass are highly reflective materials. It require a laser cutter with an „anti-reflection device“ for cutting. Brass having a thickness of 1 mm or less can cut with nitrogen.Copper having a thickness of 2 mm or less can cut.

Effect of different auxiliary gases – Damon

/in /by

Effect of different auxiliary gases – Laser cutting machines use different auxiliary gases to cut different materials. The thickness of the cutting material is different. And the pressure and flow of the auxiliary gas are different. The pressure of the auxiliary gas has a direct impact on the result of laser cutting. The working gas of the laser is  to generate laser light. The shielding gas is to protect the optical devices and drive the shutter. The working gas of the laser mixed with helium, nitrogen and carbon dioxide gas in a certain ratio.

The auxiliary gas can not only blow away the slag in time but also cool the workpiece and clean the lens. The use of different auxiliary gases can change the cutting speed and the surface quality of the slit. So it is of great significance for the cutting of special metals. The types of auxiliary gas are oxygen, air, nitrogen, and argon. Air and nitrogen can be as protective gas during cutting to prevent the occurrence of oxidation film. We use argon for titanium metal cutting.

Effect of different auxiliary gases-Compressed air

Air is suitable for cutting aluminium, non-metal and galvanized steel. To a certain extent, it can reduce the oxide film and save costs. We generally use air when the cutting plate is relatively not thick and the cutting end face is not too high.  Some sheet metal cabinets and other industries generally use air cutting.

● Nitrogen

Nitrogen is an inert gas. It could prevents oxidation of the cutting end surface of the product when cutting and prevents combustion( prone to occur when the sheet is thick). Nitrogen is for products that require higher cutting end faces and do not need to expose. Such as some decoration industry, aerospace and other special parts.

● Oxygen

Support combustion mainly use oxygen. It can increase the cutting thickness and cutting speed. Thick plate cutting, high-speed cutting and very thin plate cutting mainly use oxygen cutting. For some larger carbon steel plate and some thicker carbon steel plate structural parts, oxygen is useful.

Advantage of High Power Laser Cutting Machine

Why high-power laser cutting machine is popular?

Advantage of High Power Laser Cutting Machine

With the development of laser technology,High-power laser cutting machines can use air cutting when cutting carbon steel materials of more than 10mm.

The cutting effect and speed are much better than those with low and medium power limit power cutting.

Not only has the gas cost in the process reduced, and the speed is also several times higher than before.

It is becoming more and more popular among metal processing industry.

The super high-power fiber laser cutting machine technology has obvious advantages when cutting metal materials of different thicknesses.

you must choose the appropriate cutting speed, otherwise it may cause several bad cutting results.

The main manifestations are as follows: What is the effect of the cutting speed of the high-power fiber cutter?

1. When the laser cutting speed is too fast, it will cause the following undesirable results:

① The phenomenon of inability to cut and random sparks;

②The cutting surface has oblique stripes, and melting stains are generated in the lower half;

③The whole section is thicker, and there is no melting stain;

2. When the laser cutting speed is too slow, it will cause:

①The cutting surface is rough, causing over-melting.

②The slit becomes wider and melts at the sharp corners.

③Affect the efficiency of cutting.

Therefore, in order to make the ultra-high-power fiber laser cutting machine better perform its cutting function,

you can judge whether the feed speed is appropriate from the cutting spark of the laser equipment:

1. If the sparks spread from top to bottom, it indicates that the cutting speed is appropriate;

2. If the spark tilts backward, it indicates that the feed speed is too fast;

3. If the sparks appear to be non-spread and less, and condense together, it indicates that the speed is too slow.

So, with a good and steady laser cutting machine, and on time online afterserivce is also important to ensure the use of laser cutting machine.

Fiber laser cutter auxiliary gas

What are the reasons for the power drop of the laser cutting machine?

Fiber laser cutting machine auxiliary gas

First of all, what is the role of fiber laser cutting machine auxiliary gas?Why do fiber laser cutting machines use auxiliary gases?

There are four reasons

Firstly the ability to chemically react the auxiliary gas with the metal material, increasing its strength.

Secondlyy to help the equipment to blow off the slag cutting area, clean the slit.

Thirdly to reduce the size of the heat-affected zone through the adjacent areas of the cooling joint.

Fourthly to protect the focal length lens and prevent the optical lens from being polluted by combustion products.

What are the commonly used auxiliary gases for fiber laser cutting machine?Can air be used as an auxiliary gas?

Laser cutting experts tell you, fiber laser cutting machine in cutting metal sheet, you can choose nitrogen, oxygen, air these three types of gas as an auxiliary gas.

Their functions are as follows:

N:

When cutting stainless steel, aluminum and other color plates, nitrogen is used as an auxiliary gas cooling and protection material.When cutting metal section, it is relatively bright and the effect is good.

Oxygen:

When cutting carbon steel, you can use oxygen, because oxygen has cooling and accelerated combustion, can accelerate the cutting.The cutting speed is the fastest of all gases.

Air:

To save costs, air is used to cut stainless steel, but with fine burrs on the back.Just sand it down with sandpaper.This means that fiber laser cutters can choose air as an auxiliary gas when cutting certain materials.And in the use of air to choose air compressor.

But laser cutting experts suggest, for example, a 1000 watt fiber laser cutting machine.1mm of carbon steel and stainless steel is best cut with nitrogen or air, the effect will be better.Oxygen burns the edges, which is not ideal.

I hope it helps you.If you have any questions about the machine, please feel free to contact XT Laser.

The role of fiber laser welding machine protective gas-Dora

/in /by

The role of fiber laser welding machine protective gas

Fiber laser welding machine operation-Nancy

Fiber laser welding machine protective gas will affect weld formation, weld quality. It will also affect weld penetration depth and penetration width. In most cases, protective gas will have a positive effect on the weld. but it may also cause damage. Come unfavorable effect.

Positive effects of protective gas

1) Protect the weld pool to reduce or even avoid oxidation effectively;

2) Reduce the spatter generated during the welding process effectively;

3) Promote the uniform spread of the weld pool during solidification. So that the weld is formed uniformly and beautifully;

4)Reduce the shielding effect of the vapor plume on the laser effectively. And increase the effective utilization rate of the laser;

5)Reduce the weld pores effectively.

As long as the gas type, gas flow rate, and blowing method are selected correctly, the desired effect can be obtained.

Negative effects of protective gas

1) Incorrect blowing of protective gas may cause deterioration of the weld:

①Selecting the wrong gas type may cause cracks in the weld, and may also reduce the mechanical properties of the weld;

②Selecting the wrong gas blowing flow rate may cause more serious oxidation of the weld (whether the flow is too large or too small), and may also cause the weld pool metal to be seriously interfered by external forces, and cause the weld to collapse or form unevenly;

③Selecting the wrong gas blowing method will cause the welding seam to fail to achieve the protection effect, or even basically no protection effect, or have a negative impact on the welding seam formation;

2) Blowing in protective gas will have a certain effect on the weld penetration, especially when welding thin plates, it will reduce the weld penetration.

Types of fiber laser welding machine protective gas

Fiber laser welding machine operation-Nancy

Commonly fiber laser welding machine protective gas mainly include N2, Ar, He, and their physical and chemical properties are different, and therefore their effects on the weld are also different.

Nitrogen N2

The ionization energy of N2 is moderate, higher than that of Ar and lower than that of He. Under the action of laser, the ionization degree is average. Which can reduce the formation of plasma cloud, and increase the effective utilization rate of laser. Nitrogen can chemically react with aluminum alloy and carbon steel at a certain temperature to produce nitrides, which will increase the brittleness of the weld, reduce the toughness, and will have a greater adverse effect on the mechanical properties of the weld joint. Therefore, we do not recommend to use nitrogen to protect aluminum alloy and carbon steel welds.

The nitride produced by the chemical reaction between nitrogen and stainless steel can increase the strength of the weld joint, which will help improve the mechanical properties of the weld. Therefore, using nitrogen as a protective gas when welding stainless steel.

Argon Ar

The ionization energy of Ar is relatively low, and the ionization degree is high under the action of laser, which is not conducive to controlling the formation of plasma cloud, and will have a certain impact on the effective utilization of laser. However, the activity of Ar is very low and it is difficult to chemically interact with common metals. The cost of Ar is not high. In addition, the density of Ar is higher, which is beneficial to sink to the top of the weld pool, and can better protect the weld pool, so we use it as a conventional protective gas.

Helium He

He has the highest ionization energy, and the ionization degree is very low under the action of laser, which can well control the formation of plasma cloud. Laser can act on metal very well, and He has very low activity and basically does not chemically react with metal. It is a good shielding gas for welding seams, but the cost of He is too high. Generally, mass production products will not use this gas. We generally use it for scientific research or products with very high added value.

How to Choose the Auxiliary Gas of Fiber Laser Pipe Cutting Machine?-Serena

/in /by

How to Choose the Auxiliary Gas of Fiber Laser Pipe Cutting Machine?

When using fiber laser cutting machine, it need to be equipped with auxiliary gas. This is also applied to fiber laser pipe cutting machine. Auxiliary gas choose usually contains oxygen, nitrogen and compressed air.

The applicable conditions for the three gases are different. So the following are the differences of them.

1. Firstly,Compressed air

Compressed air is suitable for cutting aluminum sheets and galvanized steel sheets, which can reduce the oxide film and save costs to some extent. Generally, the cutting sheet is relatively thick, and the cutting surface is not required to be too perfect.

2.Secondly, Nitrogen

Nitrogen is a kind inert gas. It prevents sheet surface from oxidation during cutting, and prevents burning (it is easy to occur when the sheet is thick).

3. Thirdly,Oxygen

Oxygen mainly acts as a combustion aid, which increases the cutting speed and thickens cutting thickness. It is suitable for thick plate cutting, high speed cutting and sheet cutting，such as some large carbon steel plates, thick carbon steel structural parts.

Although increasing the the gas pressure can improve the cutting speed, the high cutting speed also will cause a decrease after reaching a peak vaortant to contrlue. Therefore, when debugging the machine, it is very impol the air pressure.
