1. Difference in working principleThe laser welding machine uses high-energy laser pulses to locally heat the material in a small range. The energy radiated by the laser diffuses into the material through heat conduction, so as to melt the material and form a specific molten pool.


The ultrasonic welding machine uses an ultrasonic generator to convert a current of 50 / 60Hz into electric energy of 15, 20, 30 or 40KHz. The converted high-frequency electric energy is again converted into mechanical motion of the same frequency by the transducer, and then the mechanical motion is transmitted to the welding joint through a group of horn devices that can change the amplitude. The welding joint transmits the received vibration energy to the joint part of the workpiece to be welded, and in this area, the vibration energy is converted into heat energy by friction, so as to melt the plastic.
2. Respective advantagesUltrasonic welding machine has the advantages of high speed, energy saving, high fusion strength, good conductivity, no spark, near cold machining, etc. It adopts electronic program control, high power, high efficiency, automatic control, easy operation, built-in electronic protection circuit, safe use, stable and reliable operation. The weldment has the characteristics of firm welding surface, high strength, subjective and environmental protection.Laser welding machine is a new welding method, which is mainly used for the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, lap welding, seal welding, etc. It has high width ratio, small welding width, small heat affected zone, small deformation, fast welding speed and smooth and beautiful welding. Treatment or simple treatment is required after welding, with high welding quality, no pores, accurate control, small focus, high positioning accuracy and easy automation.
3. Applicable products
Ultrasonic metal welder is suitable for welding thin products. It can be used for the welding of the same metal, and can also be used for single point and multi-point short strip welding of thin non-ferrous metals (such as copper, silver, aluminum and nickel). It can be widely used for welding of various shapes, such as the connector of fuse type lithium battery. Ultrasonic metal welding machine is used for similar welding of metals, and can carry out single point and multi-point short strip welding for fine and thin materials of copper, silver, aluminum and nickel non-ferrous metals. It can be widely used for welding of fuse links, lugs of lithium batteries and other shapes.


Ultrasonic welding machineUltrasonic welding machine can be divided into automatic welding machine, semi-automatic ultrasonic welding machine and manual welding machine according to the automation level. For modern enterprises, the higher the automation level, the more conducive to the enterprise assembly line production. Therefore, the use of automatic welding machine is a trend in the future.Laser welding machine
Laser welding machine, also known as laser welding machine and laser welding machine, is a machine for laser material processing. According to its working mode, it is divided into laser mold welding machine, automatic laser welding machine, laser spot welding machine and optical fiber transmission laser welding machine. Laser welding uses high-energy laser pulse to heat materials locally in small areas, The energy radiated by laser is diffused inside the material through heat transfer, and the material is melted to form a specific molten pool to achieve the purpose of welding.

How does the laser welding machine operate1 Laser welding machine has many applications in the field of industrial processing. How to avoid some potential safety hazards in the process of laser welding machining? Let's talk about the operating procedures of laser welding machine.1. Carefully read the product operation manual of the laser welding machine, and operate the laser welding machine in strict accordance with the operating procedures to ensure the safety of equipment and personnel.


2. In the process of laser welding machine, we also need to pay attention to keeping the environment and laser welding machine clean. We should often check whether the laser rod and optical elements are polluted.3. The shell of the laser welding machine needs to be connected with safety grounding. During operation, do not face the laser beam with your eyes, and do not let your body (such as hands) contact the laser beam, so as to avoid injury.4. If the laser welding machine needs to be overhauled, it must be powered off, and it must be confirmed that the charge on the energy storage capacitor has been discharged before it can be overhauled, so as to avoid electric shock accidents. In case of any abnormality during operation, power off (press emergency stop and air switch) for inspection.
5. The circulating water in the laser welding machine must be kept clean, otherwise it will affect the output size of the laser. The user can determine the cycle of changing the cooling water according to the startup time, water quality and other conditions. Generally speaking, the water change cycle in summer is shorter than that in winter.2 During the operation of the laser welding machine, there are certain requirements for the working environment, and the ventilation device is also very important for the laser welding machine, because the ventilation device directly affects the laser processing effect. Here is an explanation of the ventilation device of the laser welding machine:First: local exhaust
In the process of laser welding machine processing, there will be an exhaust device, so the exhaust device is also a kind of ventilation device. It is composed of exhaust fan, which is used to alleviate the local exhaust, which can improve the processing effect and indirectly protect the environment.The second type: comprehensive ventilationThe so-called comprehensive ventilation means to ventilate the environment in the working room of the laser welding machine, dilute the air inside, and purify the air inside to achieve a good working environment. This way can indirectly improve the processing effect. The above two schemes are commonly used in ventilation devices at present. Mastering the methods can ensure the convenience of operators, improve the processing effect and make the work of laser welding machine more satisfactory.
These two schemes are commonly used in ventilation devices at present. Mastering good methods can ensure the convenience of operators, improve the welding effect and make the work of laser welding machine more satisfactory.Selection of laser welding machineNow there are countless laser welding machines on the market. Laser welding machines can be widely used in all walks of life in today's social environment. Now many colleges and universities will also buy teaching laser welding, which is not only used for teaching but also for scientific research. If you want to buy such a device, So the businesses in the market are basically flocking. It can be said that there are many manufacturers of laser welding machines in the market. In the face of so many manufacturers, how can we choose a good equipment.


1. Confirm whether the product is suitable for welding with laser welding machineWhen selecting laser welding, we must first confirm that our products are suitable for laser welding. Now many laser welding manufacturers basically provide free proofing, so we can ask the other party to proofing before purchasing, so we can see whether laser welding can meet our requirements.2. The power of laser welding machine shall be considered
Laser is the core of laser equipment. The higher its power is, the higher its price will be. At the same time, because of the high power, the higher the requirements for the equipped laser rod and cooling system; Generally, the deeper the welding depth is required, the greater the power of the corresponding laser welding machine.3. Make reasonable choices according to budget and hobbiesSome people are more loyal to foreign brands, and the price will naturally be higher. Since there is no tariff problem, the price of domestic laser welding machine will be relatively low. Now the domestic laser technology has reached the international standard, and the after-sales problems will be handled more timely and conveniently, so it will be more guaranteed. We can choose according to our budget and hobbies.

Classification of laser welding machinesLaser welding machine is also often called laser welding machine, energy negative feedback laser welding machine, laser welding machine, laser welding machine, laser cold welding machine, laser argon welding machine, laser welding equipment, etc.1. According to its working mode, it can be divided into: laser mold welding machine: it is mainly used for mold repair in mold manufacturing and molding industries such as mobile phones, digital products, automobiles and motorcycles, as well as manual welding.


Automatic laser welding machine: it is suitable for automatic welding of straight line and circumference of metal workpieces. It is commonly used in mobile phone battery, jewelry, electronic components, sensors, clocks and watches, precision machinery, communication, handicrafts and other industries. Resistance laser welding machine: it is more suitable for welding two positions at the same time, such as resistance, capacitance and other electrodes. Laser spot welding machine: it is mainly designed for some irregular objects such as gold and silver jewelry, micro and small parts. It can be used for repairing holes in gold and silver jewelry, electronic components, spot welding sand holes, welding inserts, etc.
Optical fiber transmission laser welding machine: better beam quality, finer spot, stronger energy, more stable output and higher welding accuracy. It is mainly applicable to the welding of buttons, battery lugs and other products and materials with small and high precision requirements.. Sensor welding machine: it is specially used for sealing welding of various underwater sensors, temperature sensors and special sensors. Fiber laser continuous welding machine: fiber laser continuous welding machine is a machine that realizes welding through a continuous light emitted by fiber laser. The light output mode is continuous. Because of its continuity, it has stronger energy and greater heat, which can instantly melt the product welding point and realize welding. It is mainly used in medical treatment, mobile phone, battery, electronics, hardware, instrument, optical communication, aluminum and other industries.
Galvanometer laser welding machine: compared with the traditional automatic welding machine, galvanometer welding controls the direction of laser through galvanometer to form round, square and other patterns. So what moves is the laser, not the previous workbench or fixture. So it's faster and more accurate. It greatly saves time cost and labor cost. Mainly used in: toys, mobile phones, electronic products, automobiles and other industries.2. According to the laser, it can be divided into: YAG laser welding machine, semiconductor laser welding machine, fiber laser welding, etc.Characteristics of laser welding machine
Laser processing is to irradiate the surface of the workpiece with the laser beam, and use the high energy of the laser to operate, melt materials and change the surface properties of the object. Because laser has the characteristics of high brightness, high directivity, high monochromaticity and high coherence, it brings the following rare characteristics to laser processing: because it is processing without knowledge, there is no necessary impact on the workpiece, so there is no mechanical deformation; there is no "tool" wear and no "cutting force" acting on the workpiece during laser processing;


during laser processing, the laser beam has high energy density, fast processing speed and local processing, which has no or minimal impact on non laser sunlight parts. Therefore, the heat affected zone is small, the thermal deformation of the workpiece is small, and the previous machining is greater than; because the laser beam is easier to guide, discuss and construct direction conversion, it is not easy to correspond with the NC system and process simple workpieces, so it is an extremely flexible processing method; high production efficiency, stable and reliable processing quality, good economic and social benefits, and advantages of laser processing

With the development of laser welding machine getting better and better, it is faster and more convenient to repair mold with mold laser welding machine than ever before, but it is still a technical activity, which requires a lot of experience accumulation to control it. So, what precautions do we usually have when operating the mold laser welding machine to repair the mold?1. When repairing the mold with the mold laser welding machine, observe the mold and repair welding with a microscope, and observe with both eyes at the same time, so that the specific situation of the mold can be observed during observation.2. The welding wire should also be selected correctly during operation, because only the welding wire is selected correctly can the mold be repaired (the diameter of 0.2-0.8 can be melted). If it is not used correctly, the repair effect of the mold will be affected, and even the mold cannot be repaired.


3. The materials of different molds are different, including galvanized, beryllium copper and aluminum. Only by understanding the material of the mold can we set the corresponding parameters to achieve the repair welding effect.4. The mold laser welding machine must be protected by argon, and the program should be set to output argon first and then laser to prevent oxidation of the first pulse laser during continuous processing.5. When the mold is laser welded, the most common is that there are bite marks around the welding part. The welding part shall be covered by laser empty beating to prevent the occurrence of bite marks. The spot exceeds the welding position (0.1mm).
6. Parameters that can be set for the power supply of the mold laser welding machine: current 50-400a, pulse chamber 0.1-20ms, frequency car 0-50. When welding the mold normally, the processing parameters are as follows: current: 90-120, pulse width: 4-6; The frequency is 5-10. When welding beryllium copper and aluminum, the current increases by 30-50a7. CCD system (camera system) can be used for monitoring. The function is that in addition to the operator's observation from the microscope, non operators can watch the whole burning process through the display screen of the camera system.
