At present, handheld laser welding machines are widely used in sanitary ware industry, glasses industry, hardware industry, automobile industry, medical industry, electronics industry, household, kitchenware and bathroom and other industries, and gradually replace traditional welding methods.

With the development of science and technology, the welding industry has become more and more developed, and laser welding machine products have also been discussed by users. Today, I will talk about why automatic laser soldering machines are better than hand-held laser soldering machines.The handhe

Hand-held laser welding is mainly used for large and medium-sized sheet metal, cabinets, chassis, aluminum alloy door and window frames, stainless steel wash basins and other large workpieces, such as inner right angle, outer right angle, flat weld welding, and the heat affected area is small during

It can be seen from the above figure that arc welding is simply a welding spot at the connection port, and the corner gap is not welded and fixed. This kind of workmanship for saving trouble looks rough, and the fixing force of the steel frame structure is not enough, and it is also Not beautiful.

The elevator button board is laser cut In recent years, driven by investment in real estate, rail transit construction, and airport reconstruction and expansion, my country's elevator industry has developed rapidly. At present, my country has become the world's largest producer and consumer of elevators. As of November 2020, my country's elevator output is 1.140 million units. It is estimated that the elevator output will reach 1.231 million units in 2021, and the number of elevators in my country will reach 844.7 in 2021. Million units. my country will maintain the number of elevators with an annual output of more than one million units for a long time. This means that more than one million elevators each year use laser cutting production technology. The huge elevator market brings good market space for laser cutting equipment.

The above data refers to the "China Laser Industry Market Prospect and Investment Strategic Planning Analysis Report" by the Foresight Industry Research Institute. At the same time, the Foresight Industry Research Institute also provides industry big data, industry research, industry chain consulting, industry map, industry planning, park planning, and industry investment promotion. Solutions such as investment attraction, IPO fundraising feasibility study, and prospectus writing. According to the analysis of the Prospective Industry Research Institute, ultra-fast laser, laser welding, laser cleaning, laser plus supporting automation equipment may become the next growth point of my country's laser industry.

Can be divided into continuous laser and pulsed laser. CW lasers can continuously output for a long period of time, work stably, and have high thermal effects. Pulsed lasers output in the form of pulses. The main characteristics are high peak power and small thermal effects. According to the length of the pulse, pulsed lasers can be further divided into milliseconds, microseconds, nanoseconds, picoseconds and femtoseconds. Generally speaking, the shorter the pulse time , The higher the single pulse energy, the narrower the pulse width, and the higher the processing accuracy.

How should the trend of fiber lasers develop?In recent years, the demand for laser processing in China has grown rapidly, and fiber lasers have become the most widely used light source, driving the growth of related manufacturers. At the same time, this market has about 20 manufacturers, and the com

In the context of the “Made in China 2025” strategy, my country’s traditional industrial manufacturing industry is facing a deep transformation. The domestic laser equipment market will maintain a relatively rapid growth rate, with huge market potential.

welding: the welding seam is yellow, and the air pressure may not be adjusted properly What can be assured is that although the uniform motion seems to be very demanding, in actual operation, it is easy to find the ideal welding speed after repeated trials. Compared with traditional welding workmanship, handheld laser welding is quick to start and easy to adapt. This is also one of its biggest advantages. Protective gas There are two main functions of the shielding gas: 1. Exclude the air in the local area of the welding and avoid the appearance of oxide film on the surface of the material; 2. Suppress the plasma cloud generated during high-power laser welding. Stainless steel wireless welding

A new round of reports by overseas market research institutions shows that the demand for fiber laser equipment in North America, Europe and Asia is still growing. It is expected that the global market in this field will maintain an average annual compound growth rate of 7-8% in the future. Reached 2.4 billion U.S. dollars.

The application range of laser cleaning is very wide. As a major manufacturing country, laser cleaning/rust removal has great development potential in industrial applications. The occurrence of the Sino-US trade war has made domestic fiber laser manufacturers more important, and more and more domestic fiber laser manufacturers have realized that only by insisting on innovative and leading products can they enhance their core competitiveness. Only by mastering the core technology in our own hands can the opportunities of the Sino-US trade war outweigh the challenges. Since its establishment, Raycus Laser has been firmly committed to the development direction of a powerful country in science and technology, and has embarked on the vertical integration of the entire industry chain. Core components from chips to optical fibers have mastered key technologies through independent research and development and industrial mergers and acquisitions. A large-scale production. Under the general tren

Currently, lasers are divided into two categories: continuous and pulsed. Dr. Gao said: “When using continuous laser or long-pulse laser for processing, the material often needs to go through the process of solid-state heating, melting, liquid heating and vaporization. If a short-pulse laser is used, these three changes will be skipped directly. Reach the last step to realize vaporized cutting."

Figure 3. Absorption of light of different wavelengths by 921A steel and epoxy zinc-rich paint 3. The appropriate laser incident angle makes the cleaning effect twice the result with half the effort When the laser is incident at a certain oblique angle, the laser is directly radiated under the adhered particles, resulting in higher thermoelastic stress. Compared with normal incident, the contaminants are easier to be removed. In addition, the study found that as the tilt angle increases, the laser radiation area becomes wider (see Figure 4). When the tilt angle is 20 degrees, the area to be cleaned is about 10 times that of normal incidence, which effectively increases the laser The efficiency of cleaning.

Laser welding will become the next development focus of the laser industryIn recent years, as a high-quality, high-precision, low-deformation, high-efficiency and high-speed welding equipment, laser welding machines are becoming an important tool for metal material processing and manufacturing, and

What are the welding applications and difficulties of the fiber laser welding machine in the battery field?High-efficiency and precise laser welding can greatly improve the safety and service life of automotive power batteries, and will bring revolutionary advancements in automotive power technology

Advantages of fiber lasers over CO2 lasersFiber laser cutting technology is a cutting process that has only begun to exert strength in recent years. Although many companies are just beginning to understand this technology, they are also beginning to realize the difference between fiber laser cutting

5. Use optical instruments to observe the laser beam, such as binoculars, microscopes, telescopes, etc., to observe the laser beam, the possibility of laser damage to the eyes increases greatly. When using such optical instruments, strict safety calculations must be carried out, and optical filters and appropriate interlocking protective equipment must be added to ensure that the amount of reflection on the human eye is lower than the safety standard value of the laser.
