The most important function of laser automatic welding machine is to use the laser beam with very high energy density as a heat source to achieve the welding effect. Generally speaking, the use of continuous laser beam can reflect the role of welding to better achieve good welding effect at the same time. Usually there are certain technological parameters for laser automatic welding machine. Then, what are the main process parameters of laser automatic welding machine with high quality and quantity?

1. The power density requirement of laser automatic welding machine:

Power density is one of the most important parameters of laser automatic welding machine. For example, high power density can heat the surface to boiling point in microsecond time and produce a lot of vaporization, which can make the precision welding and seamless welding of processing materials better.

2. Pulse waveform of laser automatic welding machine:

Pulse waveform of laser automatic welding machine is an important element for laser welding of thin sheet material. For example, when high intensity laser beam is applied to the surface of material to be welded, most of the reflectivity of metal surface will decrease and its reflectivity will change with the surface temperature. So we should pay attention to the change of metal reflectivity caused by laser pulse waveform in laser automatic welding machine.

3. Pulse width of laser automatic welding machine:

Pulse width of laser automatic welding machine is an important parameter to distinguish material of removal and melting in laser welding. It is also a key parameter to determine the cost and volume of processing equipment. This parameter is suitable for precision machining, and the general material can be neglected.

4. Defocus of laser automatic welding machine:

Defocusing is usually a process parameter that has an effect on the quality of laser automatic welding machine. In order to prevent the evaporation of holes caused by the high power density of the spot center at the laser focus, people should pay attention to the need for defocusing during laser welding.
