Laser welding machine price | The use of laser welding equipment in the automotive industry

Laser welding technology in laser welding equipment has become a technology that has grown rapidly in recent years, and it is also a processing technology that many people are optimistic about. According to the welding method, it can be divided into two types, including thermal conductivity laser welding and laser deep penetration welding. In the early days, laser welding generally used a low-power pulsed solid-state laser to illuminate the object to be processed, and the general laser power density was very small. The heat of the second type of welding is very small, and the welding time is relatively short and the area is small, so it can be applied to the welding of relatively small precision equipment.

1. Characteristics of laser welding

The heat transmitted by the laser welding equipment will be relatively small, but the depth and width of the weld seam are relatively large, so the cost-effective. The influence of heat is relatively small, so it can shrink the workpiece or achieve a small amount of deformation, so it can be orthopedic without welding. In addition, the strength and speed of the welding seam are relatively high-quality, and it can make the surface condition better, which can avoid the cleaning after welding. In general, welding has its consistency and high stability. It can not add any metal or flux, and can also allow some dissimilar materials to be welded.

The beam of this laser welding is convenient for the staff to control effectively, and the positioning of the welding seam is relatively accurate, which can be automated. Compared with other welding technologies and processes, the investment of laser welding equipment is relatively large, but the production efficiency in the later stage will be much higher. The welding workpiece of laser welding can achieve relatively high precision, so it can reflect relatively high requirements from the equipment.

2. The production of laser welding

I believe that everyone does not know much about the production of laser welding. Here you can learn how laser welding is produced. Since 1962, there have been reports about laser welding. Later, scholars in many countries have done related research on laser welding. Around the 1970s, lasers were not developed. Everyone The key research directions are focused on pulsed laser welding. Later, with the invention of the continuous laser and its influence in the world, the research and application of laser welding have undergone earth-shaking changes.

Gradually, laser welding can be carried out on the stainless steel specimen, and penetration welding is also formed. In particular, the deep penetration welding produced by laser welding is very similar to the electron beam welding seam, forming a very clear "key hole". Later, researchers in Japan, Germany and other countries began to report the application and development of some high-power laser welding technology. Compared with the traditional CO2 laser equipment, the use of laser equipment with a relatively low average power for welding can achieve a relatively deep welding depth. Later, laser welding equipment has been developed to the equipment technology that can be transmitted with optical fibers and combined with robots, which further reflects the flexibility of the processing system. It is such a system that is very suitable for various work processing in industry and greatly improves productivity.

At present, the welding methods that can be achieved by laser welding equipment include laser conduction welding, laser welding first, and then the price of laser welding machines has reached advanced welding methods such as laser hybrid welding and laser wire filling welding after a long period of development and technological progress. . Of course, the welding structure will also change with the change of technology. For example, there are now from butt joints, tower joints to corner joints, and body joints.
