A laser welding machine, also often called a laser welder,handheld fiber laser welding machine, is a machine used for laser material processing. According to its working mode, it is divided into laser mold welding machines, automatic laser welding machines, laser electric welding machines, optical fiber transmission laser welding machines, and laser welding. The high-energy laser pulse material performs local heating in a small area, and the energy of laser radiation diffuses into the material through heat conduction, melting the material into a specific molten pool to achieve the purpose of welding.
What is the composition of a China laser welding machine?
The whole set of China laser welding machine is mainly composed of laser, optical system, laser processing machine, radiation parameter sensor, process medium conveying system, process parameter sensor, control system and collimated helium-neon laser. Due to different applications and different processing requirements, the eight parts of the laser welding equipment may not be available one by one, and the function of each part is also very different, and the selection can be determined according to the needs.
1.Control system
The main function is to input parameters and perform real-time display and control of parameters, interlocking between programs, protections and alarms.
2.Laser
Laser is an important part of handheld laser welding equipment, mainly providing light energy required for processing. The requirements for the laser are stable, reliable, and capable of long-term normal operation. For welding, the transverse mode of the laser is required to be a low-order mode or a basic model, and the output power (continuous laser) or output energy (pulse laser) can be accurately adjusted according to the processing requirements.
3.Optical system
The optical system is used to transmit and focus the beam. When performing linear transmission, the channel is mainly air. When carrying out high-power or high-energy transmission, shielding measures must be taken to avoid harm to people. In some advanced equipment, the laser is not output until the laser output shutter is opened. For focusing, lenses are usually used in low-power systems, while reflective focusing mirrors are usually used in high-power systems.
4.Laser processing machine
The laser processing machine is used to generate the relative movement between the workpiece and the beam required for processing. The accuracy of the laser processing machine determines to a large extent the accuracy of the welding or cutting of the laser welding equipment, and the processing machine generally uses numerical control to ensure the accuracy.
The above is the main content of several parts of the hand held laser welding machine. The function of each part is of course very important. Any one component may affect the overall performance, so be sure to choose a formal hand held laser welding machine manufacturer when purchasing.
How to choose the most affordable portable fiber laser welding machine
Before choosing laser welding machine equipment, whether the selected laser welding machine equipment can meet the needs of the enterprise, whether it can achieve the processing effect of the enterprise, and whether it can bring benefits to the enterprise is what the enterprise needs.
However, for laser welding machine manufacturers, the price of laser equipment is positioned at the high and low ends. In terms of processing effect, high-end equipment can make the processing effect more complete, such as processing a variety of materials and metal materials. The effect is also very good, but the price of this equipment is also higher.
If you do not have many requirements for the processing effect, it is recommended to choose equipment with medium performance, because the more functions, the better the equipment, and the more expensive it is. In addition, all its features cannot be used at the time of purchase. It just spends money on furniture, so it’s not worth it.
Therefore, when choosing precision handheld metal laser welding machine equipment, only the right one is the best. The so-called “appropriate” means that it can process merchants’ products, and the most used industries only have the performance that can meet the requirements of enterprises. This equipment is good value for money. In this way, money for purchasing equipment will not be wasted.
How much is a laser welding machine price in china?
There are two types of lasers for china laser welding machine, domestic lasers and foreign lasers. Generally speaking, foreign ones are more expensive than domestic ones. Therefore, the china laser welder built will be more expensive, so the price of lasers will also be higher. Affect the laser welding machine price in china.
1.Different models have different prices
The laser welding machine price in china will be affected by many factors. The price of different models of laser welding machines is different. Generally, the general-purpose laser welding machine is about 100,000 yuan, which can be purchased directly from the manufacturer, and the price is relatively low. It is more reasonable and the quality is more guaranteed.
2.Different configurations, different prices
Fiber laser welding machine is a high-tech product after all, and the price will certainly not be low. Many merchants have also tried their best to praise their products and how low the prices are, but they have reduced the quality in terms of configuration.
What materials can be welded by the china laser welding machine?
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 alloys such as steel and Kovar. The welding between the same materials can also satisfy the laser welding between different steels. However, the welding requirements are relatively high, not too thick, and the seam cannot be too large. Copper, aluminum, gold, and silver are more difficult to weld with high reflectivity.

What is the difference between china laser welder and ordinary welding equipment?
With the rapid development of welding technology and the continuous improvement of laser welding equipment, laser welding technology has promoted all engineering application materials to achieve laser welding. The advantages of laser welding equipment automation technology have replaced traditional welding technology, and laser welding equipment What is the difference with traditional welding equipment?
1.traditional resistance welding is used to weld thin metal parts.
The workpiece is clamped between two electrodes and the surface of the welded workpiece is melted by a large current and the electrode contact surface, that is, the workpiece is welded by resistance heating. The disadvantage is that the workpiece is easy to deform and resistive. Welding needs to be welded on both sides of the joint.
The laser welding machine only operates from one side. The electrodes used in resistance welding need frequent maintenance to remove oxides and metal adhering from the workpiece. When laser welding thin metal lap joints, it does not touch the workpiece, and the beam can also enter conventional welding. The area that is difficult to weld, the welding speed is fast.
2. argon arc welding uses non-consumable electrodes and shielding gas.
It is often used to weld thin workpieces, but the welding speed is very slow, and the heat input is much larger than that of laser welding equipment, which is also prone to deformation.
In fact, the technology of laser welding machine equipment is compared with a traditional welding machine. Laser welding machine equipment also has certain limitations. Because of the high cost of related systems, laser equipment investment will be larger than traditional welding equipment. During the welding process, the laser welding machine equipment has high requirements for assembly accuracy, and the position of the beam on the workpiece cannot be significantly shifted.
However, compared with traditional welding equipment, the biggest advantage of laser welding machine equipment is non-contact welding. The welding speed is fast, efficient, simple and easy to operate. Therefore, laser welding machine equipment is gradually occupying the market. We know that laser welding Technology is widely used in various industries, replacing the defects of traditional welding in-process applications from automobile manufacturing, shipbuilding, aerospace, industrial electronics, precision machining, etc.
How to maintain the welding gun of the chinese laser welding machine
- Regularly check and replace the contact tip. As the aperture of the contact tip becomes larger due to wear, the arc will be unstable, the appearance of the weld will deteriorate or the wire will stick (burnback); the tip of the contact tip will stick to splashes, and the wire feeding will become Not smooth; if the contact tip is not tightened tightly, the threaded connection will heat up and weld to death.
- Regularly clean and replace the spring hose. After a long time of use, the spring hose will accumulate a large amount of iron powder, dust, welding wire plating swarf, etc., which will make the wire feeding unstable. Therefore, it is important to clean it regularly. You can curl it and tap it gently to shake off the accumulation, and then blow it off with compressed air. Use a brush to wash the grease on the hose in the oil, and then blow it off with compressed air. If the spring hose is wrongly threaded or severely deformed and bent, replace it with a new hose. When changing the tube, make sure that it is suitable for the diameter and length of the welding wire used, and there should be no burrs on the cut surface.
- Inspection of the insulating ferrule. If the insulating ferrule is removed for welding, splashes will adhere to the nozzle to make the nozzle and the live part conductive. The welding torch may burn out due to a short circuit. At the same time, in order to make the shielding gas flow out evenly, an insulating ferrule must be installed.
