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.

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.
