Laser welding machine is a kind of equipment that uses laser beam for welding. In laser welding, the quality of the weld is a very important index, which directly affects the strength and tightness of the welded joint. The laser power of the laser welding machine also has an important impact on the quality of the weld.
The laser power of the laser welding machine refers to the energy output of the laser per unit time. The size of laser power directly affects the heat source of laser welding. In the welding process, the greater the laser power, the more heat is generated, so that the welded joint can be better melted, so that it can be well melted deep and wide, so as to improve the quality of the weld.
In laser welding machine, there is a certain relationship between laser power and weld quality. On the one hand, when the laser power is too low, it cannot provide enough heat and cannot completely melt the welded joint, so that the depth and width of the welded joint are not enough. In this way, it is easy to appear that the weld does not meet the design requirements, which seriously affects the strength and tightness of the welded joint.
On the other hand, when the laser power is too high, too much heat will be generated, which will overheat the welded joint, resulting in the overburning of the melt zone and the generation of defects such as pores. Too high laser power can also easily lead to the deformation of welded joints and the increase of residual stress, affecting the integrity and stability of the weld. In addition, the welding speed is slow at high laser power, which is not conducive to improving production efficiency.
Therefore, it is very important to choose the appropriate laser power in the laser welding machine. In practical applications, it is necessary to determine the size of the laser power according to the nature of the welding material, the structure and requirements of the welding joint, and the requirements of the welding process.
In general, there is a certain relationship between the laser power of the laser welding machine and the quality of the weld. Appropriate laser power can provide enough heat source to make the welded joint melt well, thus improving the quality of the weld. However, too low or too high laser power will cause the welding quality to decline, and even the welding seam does not meet the design requirements. Therefore, in the laser welding process, it is necessary to choose the appropriate laser power according to the actual situation to ensure the stability and reliability of the weld quality.
