How to judge the welding effect of metal laser welding machine?

    In today's society, metal laser welding machines also occupy a very important part in related fields. As a consumer, the most worrying thing about it is the quality of its welding, and how to judge this? I think it should be judged from four aspects.

    1. It is necessary to accurately judge the melting phenomenon during the welding operation. Its strength depends on the composition of many factors. For example, the time, power density and peak power of the laser acting on the surface of the material. As long as these factors are well controlled, a variety of welding processes can be performed using lasers. In addition, there is one most critical factor - the focusing position of the beam during welding. With the same factors as laser power and welding speed, focusing in the optimal range will provide maximum penetration and better weld shape.

    2. In order to judge the welding effect, the most basic thing is to be familiar with the welding method of the metal laser welding machine. There are two common laser welding methods, the first is pulse laser welding. It is mainly used for single-point fixed continuity and welding of thin materials. When welding, they become circular solder joints. The second is called continuous laser welding. The main function is the welding and cutting of large and thick parts, and a continuous weld is gradually formed during the welding operation. In addition, it is also necessary to understand the selection of basic welding materials, the selection of metal laser welding machines, and the selection of processing workbenches, which all affect the effect of laser welding. Therefore, it is necessary to reserve relevant knowledge about it before making a judgment, so that progress can be made.

    3. Selection of frequency of laser welder machine. When using the metal laser welding machine, the staff will make adjustments according to the customer's requirements on efficiency. The main purpose of adjusting the frequency parameters is to improve the welding efficiency, especially when performing some delicate metal laser welding, when it is matched with the galvanometer and scanning system, the effect of the frequency will be greater. How to adjust to the appropriate frequency is a technical problem, and it is also related to other aspects. In short, only by improving the overall effect to the extreme, it is possible to obtain a perfect welding effect.

    4. Monitoring of tensile strength of metal laser welder. When the machine is working, check whether its ability to expand the tensile strength meets our needs, and then judge the quality of the welding effect according to the inspection results. If there is poor welding during the period, various factors should be considered, starting from the essence rather than the surface. It may be that there is an error in the welding machine, or the selection of the material may be incorrect, so the material should be replaced first, or the data of the waveform of the metal laser welding machine should be changed, and then after welding again, an effect evaluation should be carried out.

    Therefore, if you are familiar with the above aspects, you can better distinguish the welding effect of the fiber laser weld machine. Of course, everything needs to be tested in the field.
