Aluminum laser welding process

     Aluminum laser welding process

Overview of aluminum welding

Aluminium and aluminum alloys have good performance, such as high specific strength, corrosion resistance, have a very wide range of applications in many industries, particularly in the defense industry, machinery and other industries, non-ferrous metals and aluminum belong in the application process requires welding, so with the rapid development of science and technology, research of aluminum welding technology is more and more depth. Therefore, the laser welding technique is a major advance in science and technology.

Overview of laser welding technology: laser welding as a new welding technology, direct heat source is a laser welding, both to avoid waste of energy, but also can greatly improve the welding efficiency. At the same time, the laser welding robot or CNC machine tools as a movement system, reduce participants can reduce the waste of labor, improve the welding efficiency. Laser heat source in addition to the advantages of renewable and clean pollution-free, but also can transmit high degree of focus and good performance, so you can converge all the energy concentrated at one point, to avoid heat loss and waste. Therefore, laser welding can improve welding efficiency and speed and the quality of the welds. Because the laser beam welding by continuous or pulsed laser beam to achieve, and therefore when the laser beam is irradiated directly on the surface of the aluminum alloy, the heat can be rapidly diffused into the surface of the metal inside the aluminum, the aluminum alloy melted to form a fast a weld simultaneously formed on the metal melted a reaction that will eventually melted down aluminum surface depressions formed holes. This hole has a powerful effect, all the energy generated can absorb the laser beam irradiation, and also create tension high-temperature steam, the steam pressure and the parietal surface to form a dynamic balance.

Laser welding power 1.1

Laser welding has some power, only when the welding power reaches a certain height in order to allow welding to stable and sustainable, otherwise the welding work only on the surface of aluminum, making the surface of aluminum melts, thereby welding can not succeed performed. Laser welding power can reach the surface of the aluminum alloy and internal height of all welding, even higher than this, the laser welding of aluminum alloy grade can improve the efficiency and speed and quality.

Laser welding speed 1.2

Because of high power laser welding, so the welding speed can be increased accordingly, to continuously improve the welding speed decreasing penetration can be made, on the contrary, if the speed is slowed down, it will be over the aluminum alloy to be welded or weld penetration and, Therefore, the choice of welding laser welding can reduce the proportion of failed and thus greatly reduce welding costs.

1.3 Advantages of laser welding

Increase energy density, improve the welding quality and increase welding accuracy and density, welding efficiency, high-speed, low cost welding, welding can be performed under special conditions, affect other parts of the small aluminum alloy welding.

2 laser welding applications in various fields

2.1 Application of the oil pipeline

In the oil pipeline, the application of aluminum pipes can be increased diameter pipe, pipe wall thickening of the oil pipeline, so that the pipeline can transport more oil within a certain time. Oil transport has a very high risk, such as the quality of the oil leak, for property damage is difficult to estimate the casualties and pollution of the environment and groundwater pollution, so the aluminum pipes must pay special attention during welding, improving welding laser welding at this point you can play a huge role, by laser welding, can be controlled in line with the welding process, the welding operation can be carried out under the premise without beveling, welding forming, high-quality welds, full to avoid the risk of oil spills, improve the security of oil transportation.

2.2 applications in the automotive manufacturing industry

With the rapid development of the times and people's living standards increasing speed, go by car have become accustomed to, and the quality requirements of the automotive people have become more sophisticated, so the automobile industry are constantly looking for new materials and techniques to improve car quality, laser welding technology in the automotive industry to the more widely used. The first US aluminum laser welding technology into the automotive industry to which, after a series of experiments, the laser welding of aluminum alloy out of the car, a thin aluminum laser welding after molding manufacturing, not only greatly reduce the weight of the body and reduces the automobile manufacturing process, improve production efficiency, the majority of the automotive industry welcomed with favor.

2.3 in the aerospace industry

As we all know, the aerospace industry requires a highly precise highly accurate material manufactured aircraft and a series of spacecraft, and also very stringent weight requirements for the machine itself, with the laser welding of aluminum alloy planes and other machines that can make the body than usually about 20% can reduce the manufacturing cost has been greatly reduced. For example, the German condominium component manufacturers using laser welding technology to produce aluminum alloy A350 family of aircraft parts and achieved great success.

3 difficulty laser welding technology of aluminum

3.1 aluminum alloy reflective laser

Because aluminum is a non-ferrous metals, all kinds of light have a very strong reflection of the laser beam as a more intense, the surface of the aluminum alloy is more likely to cause reflection, in other words, non-ferrous metals such aluminum for the laser light having a high reflectance and absorption rate smaller. In addition, the metal has a thermal conductivity, so aluminum thermal conductivity also has a strong, easy to use when laser welding, laser or heat on the reflection of the laser guide moved out quickly, resulting in the failure of aluminum welding . Therefore, in the laser welding of aluminum alloy, pay strict attention and quickly increase the power density of the laser, or prevented from being reflected is conducted, for in time with extreme high density aluminum alloy welding, so you can avoid reflective and other problems.

3.2 When the laser welding of aluminum alloy to be fully prepared

Because aluminum has a lively, susceptible to oxidation and other features on its surface easily attached to a lot of dust, water, etc., so the welding process, if not make adequate preparations, attached to the surface of things easy to stay with the rapid laser welding aluminum alloy surface, thus affecting the quality of aluminum alloys and welding results. Therefore, prior to the welding of aluminum alloy, the need for clean aluminum surface, the surface oil and other clean out. While preventing oxidation occurs during welding caused by explosions and other security threats, but also the need for a metal oxide film on the surface of a thorough cleaning, completely remove the oxide film.

Laser welding defects existing aluminum 4

Although the laser welding of high efficiency, high speed and can significantly reduce the cost, laser welding, there are many shortcomings, only to find out and solve all these defects, and be able to make aluminum laser welding technology has been more widely used.

4.1 porosity defects

In the above proposed appropriate porosity to maintain internal and external balance aluminum, however, the excess will be large number of bubble defects is difficult to avoid a large number of pores, pore instability occurs when a large number of pores in the aluminum alloy inside scurrying easy to make cracks in welded parts, so clear the pores will be one of the important defect aluminum laser welding technology need to break.

4.2 Thermal Crack

The application of laser technology, the need to raise the temperature and density in order to achieve the purpose of quick welding, so prone to crack special aluminum alloy surface, so that the weld failed, in response to thermal cracking, scientists have come up with ways to deal with that in laser welding when the use of filler material, but this method is easy to cause a lot of waste and resource-consuming labor. A more convenient way to deal with a major problem is the thermal cracking technology will solve.

5 Conclusion

Speed ​​laser welding of aluminum alloys there are a lot of advantages in a variety of manufacturing fields has been widely used, but also improve the quality of the machine itself and the manufacturing speed, but laser welding technology also has many flaws, resulting in failure of welding, I believe in the continuous efforts of scientists, the welding technology will be more mature, more and more widely.

Why there is big difference in price between Laser Marking Machine?

                          

In the procurement of fiber laser marking machine, laser marking machine and other laser equipment, you will find the current chaos laser marking machine industry has a lot of companies, large and small, and these companies will quote different prices, so we will begin to make when buying doubts, do not know where to start, but it is in that company, everyone should know the value for money this reason, the following small series to analyze price differences:

Whether fiber laser marking machine marking machine or a semiconductor or co2 laser marking machine, the business launched the device to normal use, and configuration as are many, but differ on the brand. Because different laser equipment is the most important difference caused by laser equipment prices, the laser is the use of glass fiber as a gain medium rare elements, and the formation of a high power density of particles in the broadcasting media conversion work of special applications, after working in other media eventually formed a so-called laser source. This range light source is very annoyed, used in metal and nonmetal marking / welding / cutting and other aspects, as well as industrial manufacturers are a significant advantage.

A good laser accessories laser device can give the benefits are many, first of all manufacturing and technical support costs are having on the size and cost; good fiber quality as stringent for the intake of light required Crystal Technology the location matches, you can even automatically photoelectric absorption; fiber applications are also on the overall power consumption decreased, so the lower heat loss and the amount of heat and low energy does not cause damage to anything; output energy can be divided into more energy, and increase the coordination line, multi-beam focus on the coordination of the work; for environmental requirements are more affordable, to dust, and temperature tolerance can be competent multiple environments; high conversion rates for energy use and cost savings also have good enough results.

Therefore, when you buy the device, although the same name, same address, but the price for different reasons. So when purchasing equipment, especially laser equipment can not just judge the reasons for the price, need to from the full aspects to know about.
