Comparison of laser welding machine and traditional welding method

2020-10-29 10:28:30

Laser technology is currently a major invention after electronics, computers, and semiconductors. It not only has excellent performance, but also has a wide range of applications. It can be said that the current laser application technology is changing our lives everywhere, letting us get rid of some traditional processing problems. , For us to create more quality services and products.
With the gradual popularization of laser application technology and the development of related industries, the application space of laser technology has been unprecedentedly increased. It is widely used in the current high-tech electronics, automotive manufacturing, precision processing and other fields. At the same time, the traditional processing field, More and more laser technology is used up to now.
As a direction of laser application, laser welding is a combination of current technology and traditional technology, but it has different characteristics from traditional processing. Due to the high power density and fast energy release of laser welding, the processing efficiency is better than traditional processing. The way is much superior. At the same time, after the laser is focused, the spot is small, which also makes the adhesion between the two materials better during the welding process, without causing damage and deformation of the material surface, so after the welding is completed, No need to do post-treatment to the weld.
Laser welding uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the material through heat conduction, and the material is melted to form a specific molten pool. It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, stitch welding, sealing welding, etc., with high aspect ratio, small weld width, and small heat affected zone. Small deformation, fast welding speed, smooth and beautiful welding seam, no need to handle or simple processing after welding, high welding seam quality, no porosity, precise control, small focus spot, high positioning accuracy, easy to realize automation.

The emergence of laser welding technology has given a qualitative leap in current welding technology, allowing metal and non-metal materials of different materials to be easily connected.
In the future, the application of laser welding technology will not only be in the fields of electronics, automobiles, instruments, etc., but also in the military and medical fields, especially in the medical field, with the help of the high energy and high integration of lasers. The characteristics of, pollution-free, etc. have broad prospects in the fields of neuromedicine and biological reproduction in the future.
With the continuous upgrading and transformation of laser welding machines, the precision of laser welding machines continues to improve, and the refined processing methods will allow laser welding technology to play an increasingly important role in the future micro-processing field. Although the current laser welding machine price, as well as the current laser marking machine price, and the laser cutting machine price are more expensive than the current traditional equipment, the efficiency and craftsmanship of the laser equipment has the advantages that the traditional processing methods cannot match. In the future, laser welding technology will inject new impetus into our current processing together with other laser application technologies.
