Laser Welding Machine
Laser welding machine, also often referred to as laser welding machine, is a machine used for laser material processing. According to its working method, it is divided into laser mold welding machine, automatic laser welding machine, laser electric welding machine, fiber optic transmission laser welding machine, and laser welding. High-energy laser pulses the material for local heating in a small area, and the energy of laser radiation diffuses into the material through heat conduction to melt the material into a specific molten pool for the purpose of welding.
The complete handheld laser welding machine consists of a laser, optical system, laser processing machine, radiation parameter sensor, process medium delivery system, process parameter sensor, control system and collimated He-Ne laser. Due to different applications and different processing requirements, the eight parts of the laser welding equipment may not correspond to each other, and the functions of each part are very different, and the choice can be determined according to the needs.
The main functions are parameter input and real-time display and control of parameters, program interlock, protection and alarm.
Laser is an important part of the handheld laser welding equipment, mainly to provide the light energy required for processing. The requirements for the laser are stability, reliability and the ability to work properly for a long time. For welding, the transverse mode of the laser is required to be a low-order mode or a basic mode, and the output power (continuous laser) or output energy (pulsed laser) can be precisely adjusted according to the processing requirements.
The optical system is used to transmit and focus the beam. When linear transmission is performed, the channel is mainly air. When high power or high energy transmission is performed, shielding measures must be taken to avoid harm to people. In some advanced devices, the laser is not output until the laser output shutter is opened. For focusing, lenses are usually used for low power systems, while reflective focusing mirrors are usually used for high power systems.
Laser processing machines are used to generate the relative motion between the workpiece and the beam required for processing. The accuracy of the laser processing machine largely determines the accuracy of the laser welding equipment welding or cutting, processing machine is generally used to ensure the accuracy of CNC.
The function of each part of the handheld laser welding machine is very important. Any one part may affect the overall performance, so be sure to choose a regular laser welding machine manufacturer when buying.
Before choosing laser welding machine equipment, it is important to know whether the laser welding machine equipment chosen can meet the needs of the company, whether it can achieve the processing effect of the company, and whether it can bring benefits to the company.
However, for laser welding machine manufacturers, the price of laser equipment is positioned at the high-end and low-end. In terms of processing effect, the high-end equipment can make the processing effect more perfect, 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 there is not much requirement for the processing effect, it is recommended to choose the equipment with medium performance, because the more functions, the better the equipment and the higher the price. In addition, it is not possible to use all its functions when buying. It just spends money on furniture, so it is not worth it.
Therefore, when choosing a precision laser welding machine equipment, choosing the right one is the best. The so-called "right" is the product that can process the business, and the most commonly used industry only can meet the performance of business requirements. The equipment is worth every penny. This will not waste the money to buy equipment.
There are two types of lasers for handheld laser welding machines, Chinese lasers and foreign lasers. Generally, the foreign ones are more expensive than the Chinese ones. So the built laser welding machine will be more expensive, so the price of the laser will also be higher. It will also affect the price of laser welding machine.
The cost of a handheld fiber laser welding machine can be affected by many factors. The price of laser welding machine varies from model to model.

Laser welding machines 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 alloys. Fellable. Welding between the same material can also be met with laser welding between different steels. However, the welding requirements are high, not too thick and the seam cannot be too large. High reflectivity copper, aluminum, gold and silver are more difficult to weld.

With the rapid development of welding technology and the continuous improvement of laser welding equipment, laser welding technology has promoted the realization of laser welding for all engineering applications of materials. The advantages of automated technology of laser welding equipment have replaced the traditional welding technology, and the differences between laser welding equipment and traditional welding equipment are these.
The workpiece is sandwiched between two electrodes, the surface of the workpiece being welded is melted by high current, electrode contact surface, that is, by resistance heating to the workpiece. The disadvantage is that the workpiece is easily deformed and has a high resistance. Welding needs to be performed on both sides of the joint.
Laser welders operate from one side only. The electrodes used in resistance welding require frequent maintenance to remove oxides and metals adhering to the workpiece. Laser welding of thin metal lap joints allows the beam to enter conventional welds without touching the workpiece. Areas that are difficult to weld and welding speed is fast.
Commonly used to weld thinner workpieces, but the welding speed is very slow, the heat input is much greater than laser welding equipment, but also prone to deformation.
In fact, the technology of laser welding machine equipment is compared with traditional welding machines. Laser welding machine equipment also has certain limitations. The investment in laser equipment will be larger than traditional welding equipment due to the higher cost of the associated systems. During the welding process, laser welding machine equipment requires high assembly accuracy, and the position of the beam on the workpiece must not 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 and simple to operate. Therefore, laser welding machine equipment is gradually occupying the market. As we know, laser welding technology is widely used in various industries, replacing the defects of traditional welding process applications such as automotive manufacturing, shipbuilding, aerospace, industrial electronics, precision machining, etc.
Check and replace the contacts regularly. As the aperture of the conductive nozzle becomes larger due to wear, the arc becomes unstable, the appearance of the weld deteriorates or the wire sticks (burns back); spatter can stick to the tip of the contact and wire feeding becomes uneven; if the conductive nozzle is not tightened, the threaded connection can heat up and weld.
Clean and replace the spring hoses regularly. The spring hose will accumulate a lot of iron powder, dust, wire plating chips, etc. after using for a long time, which makes the wire feeding unstable. Therefore, it is important to clean it regularly. You can crimp it and tap it gently to shake off the buildup, then blow it off with compressed air. Clean the grease off the hose in oil with a brush and then blow it off with compressed air. If the spring hose is misthreaded or severely deformed and bent, replace it with a new hose. When replacing the hose, make sure that it is appropriate to the diameter and length of the welding wire used and that the cut surface is not burred.
Check the insulation collar. If the insulating collar is removed for welding, spatter will adhere to the nozzle and make the nozzle and the electrically charged part conductive. The welding torch may burn up due to short circuit. Also, the insulating collar must be installed in order for the shielding gas to flow out evenly.
