There are three main differences between continuous fiber laser welding machine and pulsed fiber laser welding machine. We all know that there are continuous lasers and pulsed lasers. In fact, from the working principle, they are all pulsed types, but the output laser pulse frequency of continuous lasers is higher, and the human eye cannot recognize it.
Ⅰ. The product properties of continuous fiber laser welding machine and pulsed fiber laser welding machine are different：
1. It has a stable working state, that is, steady state. In a continuous fiber laser, the number of particles of each energy level and the radiation field in the cavity have a stable distribution.
2. Pulsed fiber lasers are fiber lasers with a single laser pulse width of less than 0.25 seconds and only work once every certain interval.
Ⅱ. The working characteristics of continuous fiber laser welding machine and pulsed fiber laser welding machine are different：
1. The excitation of the working material of a continuous fiber laser and the corresponding laser output can be carried out in a continuous manner over a long period of time. Solid-state lasers excited by a continuous light source and gas lasers and semiconductor lasers working in a continuous excitation mode.
2. Pulsed laser is a kind of laser with a large output power; we are usually suitable for laser marking, cutting, ranging, etc. the advantage of our pulsed fiber laser welding machine is that the overall temperature rise of the workpiece is very small, the thermal influence range is small, and the deformation of the workpiece is small.
Ⅲ. The application scenarios of continuous fiber laser welding machine and pulsed fiber laser welding machine are different：
Generally, the lasers of the continuous fiber laser welding machine we use can be used with the control software to achieve the effect of special solder joints. This is one of the reasons why it can be widely used for spot welding and continuous welding of various devices. .
Most of the continuous fiber laser welding machine welds are high-power lasers with a power of more than 500 watts. Generally, this kind of laser should be used for plates above 1mm.The mechanism of it is deep welding based on the small hole effect. The aspect ratio is large, which can reach more than 5:1, the welding speed is fast, and the thermal deformation is small. Our continuous fiber laser welding machine is widely used in machinery, automobiles, ships and other industries.There are also some low-power continuous lasers with a power of between tens and hundreds of watts. They are used more in industries such as plastic welding and laser brazing.
We apply the principle of laser pulse scanning welding, which is widely used in the welding of dissimilar non-ferrous metal flakes, especially for the welding of new devices in the consumer electronics industry.
Pulsed laser welding is mainly used for spot welding and seam welding of thin-walled metal materials within 1mm thickness. The welding process of our pulsed fiber laser welding machine belongs to the heat conduction type, that is, laser radiation heats the surface of the workpiece, and then diffuses to the inside of the material through heat conduction. By controlling the waveform, width, peak power, repetition frequency and other parameters of the laser pulse, a good connection is formed between the workpieces.It has a large number of applications in 3C product housings, lithium batteries, electronic components, mold repair welding and other industries.
