Latest company news about Why is it air-cooled? For laser welding

Early handheld laser welding machines used water cooling for heat dissipation. This method is simple in structure and easy to maintain. It has made great contributions to the market development of handheld laser welding from 0 to 1. However, in the process of use, the market gradually found that the water-cooled hand-held laser welding machine has shortcomings in portability and functional ductility. At the same time, the characteristics of anti-freezing in winter and anti-condensing in summer also increase the difficulty of equipment maintenance.
As the market demand becomes more sophisticated, some manufacturers have begun to consider using air-cooled solutions as hand-held laser welding machines.

Compared with the water-cooled solution, the hand-held laser welding machine using the air-cooled solution does not require additional water-cooling equipment, which greatly reduces the volume and weight of the equipment while reducing costs. In addition, it also provides convenience for adding functions such as cleaning and cutting in the later stage. . Some people in the industry believe that air-cooled hand-held laser welding is the key to further replacing the argon arc welding market with greater cost-effectiveness advantages and more flexible application scenarios (small size, portability, and functional extension).

Most of the current laser equipment is equipped with a chiller, the purpose of which is to keep the temperature of key components constant, avoid changes in beam quality caused by temperature fluctuations, and damage to components caused by excessive temperature. For hand-held laser welding machines, how to use air cooling to achieve the same temperature control effect as water cooling has become a bottleneck restricting the industrial application of this new concept.

The first to break through this technical bottleneck is the global leader in fiber lasers - IPG.
Just this year, China expanded the technology into practical applications. The hand-held laser welding machine with air-cooled solution sold by Riselaser has been affirmed and relied on by the majority of users
