Essential for cutting carbon steel materials—fiber laser cutting machine!

Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Theoretically, the higher the carbon content in carbon steel, the greater the hardness, the higher the strength, and the lower the plasticity.

 


So what are the advantages of fiber laser cutting machine for cutting carbon steel?


1. The cutting quality is good, the cutting seam is small, the deformation is small, the cutting surface is smooth, flat and beautiful, and no subsequent processing is required.


2. Fast cutting speed. The continuous and fast curve cutting function and the work path optimization function greatly improve work efficiency.

 

3. High stability. The output power of the equipment is stable, the laser has a long service life and is easy to maintain.

Fiber laser cutting machines have great advantages in cutting carbon steel. For carbon steel processing, it is very important to ensure the accuracy of the product, especially some hardware parts, because most of them are used in automobiles, ships, precision accessories, and household appliances. The second is the cost saving and increased efficiency of fiber laser cutting machines. As labor costs continue to increase, automated production has gradually become the mainstream of the processing industry. Therefore, laser equipment such as fiber laser cutting machines that can save labor but improve production efficiency is destined to become the focus of the market.

How to choose single pendulum and double pendulum handheld welding laser system?

Handheld laser welding is a new welding technology that is rapidly gaining popularity. Its principle is to quickly melt materials with laser to form a weld, thereby achieving the purpose of welding. Compared with traditional welding, handheld laser welding has the advantages of low entry threshold, fast welding speed, and beautiful welds. Therefore, it has achieved rapid growth in sales in the market in recent years.

Handheld welding laser equipment requires a control system to adjust processing parameters such as power size and focus shape. Currently, handheld welding mainly uses embedded controllers as the control system. Since the galvanometers that control the laser direction include single swing motors and double swing motors, Handheld laser welding control systems are also divided into two types: single pendulum control system and double pendulum control system.


The swing motor adjusts the direction of the laser by controlling the galvanometer. A single motor can only control changes in a single direction, similar to a single X-axis or a single Y-axis, while dual motors can be combined with each other to enable the galvanometer to turn to any angle, achieving a more Complex welding process.


Under normal circumstances, there is not much difference between the single-pendulum handheld laser welding control system and the double-pendulum handheld laser welding control system in terms of main functions such as laser control, information display, parameter setting, and safety alarm. The same device, two types of control There won’t be much difference in the system’s welding speed and weld appearance.


However, because the double pendulum system can freely control the laser angle, the double pendulum handheld laser equipment can process complex parts, such as parts with included angles and dead ends. These parts where the laser head cannot be directly aimed require adjustment of the double pendulum control system. The laser angle allows operators to complete processing without alignment.


In addition, some welding tasks that require higher precision or more complex welding paths also require a double-pendulum control system. This is also the largest functional difference between the single-pendulum handheld laser control system and the double-pendulum handheld laser control system. difference.


In terms of price, the price of the pendulum handheld laser control system is relatively low, and the overall price of its supporting pendulum handheld laser welding machine is also relatively low. For general sheet metal processing, such as furniture welding, billboard welding, kitchen cabinet welding, etc. It is sufficient to use a single-pendulum handheld welding control system, but complex tasks still require dual-pendulum handheld welding to complete. The specific choice depends on your own requirements.

Why are the protective lenses often burned when using laser welding machines?

The protective lens of the laser welding machine is consumable, so it needs to be replaced regularly. However, due to the influence of the process/technique/setup, etc., it may cause damage by slag retrieval. In rare cases, abnormal laser light output and other factors may also easily lead to the protective lens of the laser welding machine equipment burned out when being used. What causes the protective lens of the laser welding machine to burn out and how to deal with it?


Analysis of the causes of burnt protective lenses:

To prevent improper use of laser welding machine equipment, which often causes the protective lens to be burned out, we can extend the life of the protective lens of the laser welding machine from the following aspects.

1. First consider whether the auxiliary gas we blow is pure. Whether the pressure meets the standards. If you are blowing air, you need to check the quality of the compressed air.

2. Check whether the optical path is deflected during the laser emission process, and whether other lenses are damaged during the operation.

3. Check whether the hole diameter of the applicable nozzle is too large.

4、Check whether the timing configuration of the software for punching and blowing is reasonable.

How to correctly reduce the loss of protective lenses:

1. Increase the air pressure appropriately. Normally, the flow rate is not less than 15 and the pressure is not less than 4. It is recommended to use an oxygen pressure gauge not less than 2 kg.

2. When welding, try to weld the welding gun and the plate at a 45° angle, not vertically

3. Set the parameters as slowly as possible, such as gas on/off delay 200-500ms, light on/off power 20%, light on/off gradual time 200-300ms, and cannot be set to 0

4. When welding aluminum and galvanized sheets, this material will damage the lens more easily than other materials, so the minimum power should be used for welding

 

5. The quality of protective glasses also determines their durability. It is recommended to use original lenses

6. Under high power, compared with low power, the loss of the lens will increase, which is an uncontrollable range

7. When none of the above can be dealt with, you can replace the F200 focusing lens + lengthened wide scale tube to reduce splashing

The above is an analysis of the reasons for the burnout of the protective lens of the laser welding machine and a brief introduction to reducing the loss of the protective lens. When using laser welding equipment, some minor faults often occur due to improper operation or lack of attention to maintenance. Therefore, it is recommended that customers use When using laser welding equipment, it is best to undergo professional training and perform routine maintenance on the laser welding equipment.

What are the functions of laser marking machine speed, power and frequency?

1. The speed of the marking machine: This refers to the speed of the laser scanning galvanometer. This speed refers to the speed that can be adjusted in the parameters, rather than the overall speed of marking a product. Because the overall marking speed is not only adjusted by the speed parameters, but also affected by factors such as marking depth and marking area. The function of the marking speed parameter is that when other conditions are constant, the faster the speed, the faster the marking speed.

2. The power of the marking machine: In the parameter settings, the power is adjusted by percentage, and the output power can be adjusted from 0% to 100%. The general default parameter is 50% output power. The larger the output power is adjusted, the greater the laser output energy will be, and the easier it will be to drill deeper. However, how much output power should be adjusted should be chosen according to your actual needs, because if the output energy is too large, the impact on the material will be greater. If you can achieve the effect you want, you don't need to turn on more power, otherwise the load will be high for a long time. If it works, it will have an impact on the service life of the laser.

 

3. Frequency of the marking machine: The number of pulses per unit time is called the marking frequency of the fiber laser marking machine. If the marking frequency is high, the laser points will be dense; if the marking frequency is low, the laser points will be loose.

Five ways to adjust the marking depth of laser marking machines!

During the operation, choosing different parameters and marking workpieces of different materials will affect the marking depth of the laser marking machine, sometimes resulting in the marking effect being too shallow or too deep. In fact, the marking depth of the laser marking machine is It can be adjusted to a certain extent. The following are five methods to adjust the marking depth:

1. Increasing the laser power can directly increase the depth of laser marking, but the prerequisite for increasing the power is to ensure the laser power supply. Laser chillers, laser lenses, etc. must also be matched with it. The performance of its related accessories must withstand the performance after the power is increased. Therefore, sometimes it is necessary to temporarily replace the accessories, but the cost will increase, and the workload or technical requirements will increase. .

 

2. Replace with better laser marking accessories. For example, if you use imported Q-switch for laser marking of semiconductor machines, the marking depth will be better.

 

3. Change the field lens of the laser marking machine into a small-range field lens. After the change, the marking depth will be deeper. For example, the current semiconductor laser marking machine can be equipped with a 110 field lens, becoming With the addition of a 50 field lens, the total laser energy and engraving depth will be approximately twice the previous results.

 

4. If the laser mode of the laser marking machine is made better, the marking depth will also be improved to a certain extent. For example, in the case of semiconductor laser marking, small holes are added to increase the cooling accuracy, and the laser mode is adjusted to emit light so that the laser Bigger, rounder, brighter.

 

5. Slow down the marking speed of the laser marking machine. With the same power and the same other parameters, if you only modify the marking speed, the marking depth will of course be deeper.
