Compared with traditional welding, laser welding is a revolutionary technological advancement. With its fine weld, large depth, small taper and high precision, the laser has the characteristics of smooth, smooth and beautiful appearance. Power density is one of the most critical parameters of laser processing. The magnitude of laser power has a great influence on the quality of laser welding. So what is the relationship between laser welding machine power and various parameters?

Average laser power: The actual output laser power is approximately equal to 2-3% of the average injected electrical power.

Pulse Width: The time of a single pulse.

Pulse frequency: The number of repetitions of the laser pulse per second.

Laser peak power: The instantaneous power of the laser when it is actually emitted. The peak power of the laser is equal to the average power divided by the duty cycle. It is generally on the order of several kilowatts.

Laser pulse energy: refers to the energy output by a single pulse. It is determined by the storage capacitor capacity, voltage and xenon lamp. This is an important indicator of laser welding machines. At the time of spot welding, the stability of single point energy has a great influence on the quality of laser welding.

It can be seen from the above that the average power of the laser welding machine is the most important. For the pulsed laser, the average laser power is sufficient to ensure sufficient laser power to talk about other parameters.
