With the continuous upgrading and transformation of laser welding technology, there has been a qualitative leap in laser welding technology. Nowadays, laser welding machines have been maturely applied in many fields, such as high-tech electronics, automotive manufacturing, precision machining, and so on. As a direction of laser application, laser welding is a combination of current technology and traditional technology, but it has different advantages from traditional processing.
The main characteristics of laser welding areDue to the focused laser, the energy is highly concentrated, causing the welded material to vaporize at the moment it is irradiated by the laser beam, and then re solidify at the moment the laser beam moves away.
The instantaneous vaporization and solidification state of such materials can effectively reduce heat input, and the heat affected zone is very small. The thermal stress after material welding can also be reduced to the lowest possible level. However, because the entire welding process is completed instantly, laser welding can also cause other problems. Common defects include pores, cracks, inclusions, and crystalline fractures. In addition, phenomena such as shrinkage, collapse, and uneven surface are also common in laser welding.
What are the ten advantages of laser welding machines?
1. Good quality of laser beam
After laser focusing, the power density is high. After high-power low order mode laser focusing, the focal spot diameter is small.
2. Laser welding has fast speed, large depth, and small deformation.
Due to the high power density, small holes are formed in the metal material during laser welding, and laser energy is transmitted to the deep part of the workpiece through the holes with less lateral diffusion. Therefore, the material fusion depth is relatively large during the laser beam scanning process. Fast speed, large welding area per unit time.
3. Laser welding is particularly suitable for welding precision sensitive parts
Due to its large aspect ratio, low specific energy, small heat affected zone, and minimal welding deformation, laser welding machines are particularly suitable for welding precision and heat sensitive parts, eliminating post weld correction and secondary processing.
4. Laser welding has high flexibility and agility
Laser welding machine can achieve welding at any angle and can weld difficult to access parts; Can weld various complex welding workpieces and irregularly shaped large workpieces. It has great flexibility to achieve welding at any angle.
5. Laser welding can weld difficult to weld materials
Laser welding can not only be used for welding between various heterogeneous metal materials, but also for metals such as titanium, nickel, zinc, copper, aluminum, chromium, niobium, gold, silver and their alloys, steel, Kovar alloys, etc. Welding between alloy materials.
6. Low labor cost of laser welding machine
Due to the low heat input during laser welding and minimal deformation after welding, a very beautiful welding effect can be achieved on the surface. Therefore, there are few follow-up treatments for laser welding, which can greatly reduce or eliminate the manual labor involved in the huge polishing and leveling processes.
7. The laser welding machine is easy to operate
Laser welding machine welding equipment is simple, the operation process is easy to learn, and it is easy to get started. Low professional requirements for staff, saving labor costs
