What are the advantages of using laser welding machines for plastic product welding

Hello questioner: What are the advantages of using laser welding machines for plastic product welding, let's first learn about plastic laser welding machines, and you will understand the answer to your question after reading. Thank you!

First of all, the advantages of plastic laser welding applied to the welding of plastic parts include: precision welding, firm and sealing, impermeable and water-tight, less resin degradation and less debris generated during the welding process, and the surface of the product can be tightly connected around the weld. Laser welding has the advantage of no residue, making it more suitable for pharmaceutical products and electronic sensors controlled by the State Food and Drug Administration.

It is easy to control and can weld workpieces with small dimensions or complex structures. Because the laser is easy to be controlled by computer software, and the output of the fiber laser can flexibly reach all the subtle parts of the part, the use of laser welding can weld areas that are not easy to reach by other welding methods, and weld products with complex shapes and even three-dimensional geometries.

Compared with other welding methods, laser welding greatly reduces the vibration stress and thermal stress of the product. This means that the product or internal components of the device age more slowly and can be applied to fragile parts. Capable of welding many different kinds of materials.

For example, it is possible to join together polycarbonate that transmits a near-infrared laser and black polybutylene terephthalate that is reinforced with glass fibers, while other welding methods simply cannot join two polymers that are so different in terms of structure, softening point and reinforcement.

Done, the answer is for reference only, thank you!

Laser welding machine is a kind of welding equipment that is needed in many industries, especially in the automotive industry, medical equipment manufacturing industry, mold processing industry, sheet metal industry, kitchen and bathroom industry and electronics industry. Laser welding machines have such a wide range of applications, mainly due to the fact that the role of this laser plastic welding machine is very prominent.

1. Laser plastic welding host.

Among the components of the laser welding machine, the laser welding machine is an important hardware component. The host mainly generates a laser beam for welding, and the host is composed of a power supply, a laser generator, an optical path part and a control system. In layman's terms, the laser required for laser welding is the main machine for laser plastic welding.

2. Cooling system.

The laser welding machine will also generate a lot of heat in the process of working, and too much heat will affect the welding effect of the workpiece, so the Wuhan laser trembling welding machine also needs a cooling system to provide cooling function for the laser generator, so as to ensure that the temperature required for laser welding is more appropriate.

3. a workbench.

The workbench refers to the laser plastic welding automatic table, or also known as the motion system. The workbench is to allow the laser beam to move according to specific requirements and welding trajectories, so as to realize the automatic welding function of the laser. It can be said that the workbench is the core component of Yingyun plastic laser welding machine, which mainly controls the movement of welding.

To put it simply, the main components of a laser welding machine include a laser welder, a host cooling system, and a workbench. The tooling fixture is mainly used to fix the welding workpiece, and the observation system is mainly set up for real-time microscopic observation of the welding effect of the workpiece.

Laser welding machine.

According to its working mode, it is divided into nano pulse laser welding machine, QCW laser welding machine, and YAG laser welding machine.

Laser welding equipment.

1. High flexibility.

Laser welding technology is the most advanced welding method in the field of processing, compared with the traditional welding technology, laser welding technology belongs to non-contact welding, the operation process does not need to be pressurized, the welding speed is fast, the efficacy is high, the depth of the punch, the residual stress and deformation are small. Welding of heterosexual materials has good effect and great flexibility.

2. It can weld materials that are difficult to weld.

Laser welding is the use of high energy density of laser beam fusion materials, laser welding machine has fast welding speed, high strength, narrow weld, small heat affected zone, and small deformation of the workpiece, less follow-up processing workload.

3. Less labor cost.

Because the heat input is very low in laser welding, the deformation after welding is very small, and the welding effect of the surface can be very beautiful, so the follow-up treatment of laser welding is very small, which can greatly reduce or cancel the labor on the huge polishing and leveling process.

Hello, the main advantages of laser welding compared to other welding techniques are:

1. Fast speed, large depth and small deformation.

2. It can be welded at room temperature or under special conditions, and the welding equipment is simple.

3. It can weld refractory materials such as titanium, quartz, etc., and can weld heterosexual materials with good results.

4. After laser focusing, the power density is high, and the aspect ratio can reach 5:1 and up to 10:1 when welding high-power devices.

5. Micro welding can be carried out. After the laser beam is focused, a small spot can be obtained, and it can be accurately positioned, which can be applied to the assembly welding of micro and small workpieces produced in large quantities.

6. It can weld the parts that are difficult to access, and implement non-contact long-distance welding, which has great flexibility. Especially in recent years, optical fiber transmission technology has been adopted in YAG laser processing technology, which has made laser welding technology more widely promoted and applied.

7. The laser beam is easy to realize the beam splitting according to time and space, and can carry out multi-beam simultaneous processing and multi-station processing, which provides conditions for more precise welding.

In our country, welding operations need to be licensed, welders are the type of work that belongs to the access category, in the professional qualifications of skilled personnel, only five of the 81 types of work in the access category, welders are one of them, and the actual situation is that most of the industry practitioners are unlicensed operations. With the continuous standardization of technology and the relevant requirements of the industry, more and more people want to take a welding certificate, the advantage of the certificate is still very large, first of all, the salary of the certificate and the non-certificate are very different, often able to reach more than double or higher level. Therefore, the issue of short-term welder training has naturally become a concern for practitioners.

Welding as an industrial "tailor" is a very important means of processing in industrial production, the quality of welding plays a decisive role in the quality of the product, so, what is the future development of welding technology?

Industry outlook. With the development of production, welding is widely used in aerospace, aviation, nuclear industry, shipbuilding, construction and machinery manufacturing and other industrial sectors, in China's economic development, welding technology is an indispensable means of processing. After entering the 21st century, welding is an important part of the manufacturing industry, and the rapid development, so it has brought unprecedented development opportunities to the welding industry.

At present, China consumes 300 million tons of steel every year (about tons of welded structure), and needs about 750,000 welding machines, and the welding industry will continue to grow in the next 8 10 years.

The laser welding machine can weld carbon steel, die steel, alloy steel, stainless steel, titanium, nickel, tin, copper, aluminum, chromium, niobium, gold, silver and other metals and their alloys, as well as steel, Kovar alloy and other alloys of the same material welding, can also meet the laser welding between different steels.

However, the welding requirements are relatively high, not too thick, the seam can not be too large, and it is difficult to weld copper, aluminum, gold and silver with large reflectivity.

Hope, thank you.

The ** of laser welding machines range from tens of thousands to hundreds of thousands. The laser welding machine can weld a variety of metals and their alloys, such as stainless steel, alloy steel, copper, aluminum, gold, silver, titanium, die steel, etc.

Laser welding machine is a non-contact welding method, which can achieve welding and molten pool by concentrating light to maximize the energy of light at the time of focus. Because different materials absorb light differently; The thickness of the material is different. Therefore, laser welding machines range from 25W to 20,000W, and are used in applications ranging from micromachining to high-speed rail accessories, ships, and aviation applications.

From more than 20,000 to tens of millions. It depends on your welding requirements and process requirements.

Then I'll talk about the disadvantages of Bot laser welding machine and its advantages:

The output waveform can be set arbitrarily according to the welding material, shape, etc., in the welding process of the specific workpiece, according to the shape and material of the work, the output waveform of the laser energy can be changed, which can greatly improve the welding quality, and even some traditional laser welding problems can be solved by changing the output waveform of the laser.

1. Real-time control of quantity, multiple setting of waveform, bringing precision welding quality.

2. Stability, high reliability, 24-hour stable operation.

3. Equipped with CCD coaxial monitoring system, using image segmentation device, the position of each solder joint can be observed at the same time or separately on a display through switching operation, which is simple and intuitive to observe.

4. Energy feedback fiber transmission laser welding machine uses real-time energy negative feedback, the laser energy is stable, and the size of the solder joint is uniform.

5. Over-energy splitting or time splitting can realize simultaneous welding or time-sharing welding.

6. The output waveform can be set arbitrarily according to the welding material, shape, etc.

7. Over-energy splitting or time splitting can realize simultaneous welding or time-sharing welding. Rich IO interface, users can easily control the welding machine.

8. The key components are imported from abroad to ensure the quality of the product.

The laser welding speed is fast, the welding spot is small, the heat generated during welding is very small, and the thermal deformation is very small. Weldable points, straight lines, planar arbitrary shapes and spatial shapes. The welding process can be automated. Meet the long-term continuous work of industrial sites.

Generally, it is divided into laser welding machine, galvanometer laser welding machine, and fiber laser welding machine.
