There are countless types of metal laser welding machines on the market. As a buyer, the most worried thing is how to distinguish the welding quality. So how to distinguish the welding effect of metal laser welding machine?
1. Judgment of melting phenomenon during welding operation
The intensity of the melting phenomenon during the welding operation mainly depends on the time, power density and peak power of the laser acting on the material surface. By controlling the above parameters, we can use the laser to carry out various welding processes. In the welding process of metal laser welding machine, the beam focusing position is one of the most key control process parameters. Under a certain laser power and welding speed, the maximum penetration and better weld shape can be obtained only when the focusing is in the best range.
2. Familiar with the welding method of metal laser welding machine
There are two kinds of common laser welding methods, one of which is pulse laser welding. At present, it is mainly used for single point fixed continuity and thin piece material welding, forming circular welding spots during welding; The other is continuous laser welding, which is mainly used for welding and cutting large and thick parts. A continuous weld is formed during the welding operation. Generally speaking, the selection of welding materials, metal laser welding machine and processing workbench are the main factors affecting the effect of laser welding.
3. Frequency selection of metal laser welding machine
Generally, when using metal laser welding machine, the frequency parameters will be adjusted as much as possible according to the requirements of customers for efficiency. Frequency plays a great role in the requirements of welding efficiency, especially for some precision metal laser welding. When it will cooperate with galvanometer and scanning system, the role of frequency will be greater. How to adjust to the appropriate frequency will be a technical problem, but the role of frequency will also be related to other aspects. There must be an overall effect to have a perfect welding effect.
4. Monitoring of tensile strength
Be able to monitor the tensile strength and judge the welding effect according to the inspection results. In case of poor welding and faulty welding of welding joints during processing, it may not be the welding machine at this time. Maybe the material is inappropriate. Replace the material or change the waveform setting of the metal laser welding machine, weld again, and then evaluate the effect.
The welding effect of metal laser welding machine can be distinguished according to many aspects. As long as we master the above points, it will not be difficult to distinguish the welding effect of laser welding machine. In the operation process of using metal laser welding machine, the quality control method of metal laser welding machine also needs to be mastered. Finally, I hope the above contents will be helpful to you.
