Laser welding in recent years has come into all walks of life, has become the key to the development of many industries are indispensable. However, many people do not understand the principle of laser welding, do not know why this welding equipment as well as technology can be completed on the basis of non-contact welding work. Next DMEC will share the welding principle with you.


Laser welding principle is actually through the pulsed laser beam to complete the welding. The principle can be divided into two kinds of heat conduction and laser deep fusion. The so-called heat conduction principle refers to the area to be welded for radiation heating, when the surface heat gradually through heat conduction to penetrate the material inside, it can be through the relative energy as well as the repetition frequency and the relevant laser parameters, etc. to promote the workpiece to be melted.
Laser deep melting is carried out with a continuous laser beam to achieve the joining of materials and the depth of the weld. Through the technological upgrading (subdivided into pulsed laser welding and continuous laser welding) pulsed laser welding ≤ 100 light points per second, while the continuous laser welding can reach ≤ 5000 light points per second, this welding principle in the sufficiently high density of laser irradiation, will make the welding material at a certain point in the rapid and efficient absorption of the laser beam energy, which will make the metal material to be completely melted and penetrated. Both welding principle is actually through the laser heat source to achieve welding, can ensure that a higher degree of precision welding needs to ensure that the welding process is perfect, there will be no welding gap is too large to affect the aesthetics.

Through the above introduction, do you have a basic understanding of its working principle? Now China's laser welding industry has become one of the world's most widely used countries, enough to see the future development of China's laser welding industry will achieve a more comprehensive development, and gradually embark on more international stage.
