Laser welding is a widely used welding process. With the continuous innovation of welding processes, there are more and more types of laser welding equipment, but how to judge whether the welding effect is good or not? The following professional laser welding machine manufacturers teach you a few ways to judge.
1. Judging according to the melting phenomenon during the welding process:
Whether or not the melting phenomenon occurs during the welding process depends mainly on the time, power density and peak power on the surface of the laser acting on the material. If the above parameters are well controlled, the laser can be used for various welding processes. In laser welding, the focus position of the beam is one of the key control process parameters. Under a certain laser power and welding speed, only when the focus is within the optimal position range can the penetration depth and good weld shape be obtained.
2. Judging according to the laser welding method:
Commonly used welding methods mainly include continuous laser welding and pulse laser welding. Continuous laser welding is mainly used for welding and cutting of large and thick parts, forming a continuous weld seam during the welding process; the other is pulse laser welding, which is mainly used for welding of single-point fixed continuous and thin materials. Form a circular solder joint; so choose a suitable laser welding machine according to the thickness of the welding material; the choice of the laser welding machine workbench is also the main factor affecting the laser welding effect.
3. According to the judgment of the frequency of the laser welding machine
When using a laser welding machine, the frequency parameters will be adjusted according to the customer’s requirements for efficiency. The frequency of laser welding has a great influence on welding efficiency. It cooperates with the galvanometer linkage scanning system to form a linkage motion trajectory. Compared with the traditional galvanometer and platform independent control system, the galvanometer linkage system can greatly improve the efficiency and accuracy of laser processing. How Adjusting to the appropriate frequency is a technical activity, and the effect of the frequency can be maximized.
4. Judgment based on tensile strength monitoring
It is possible to monitor the tensile strength, and judge where the problem of the laser welding machine is based on the inspection results. If there are problems such as poor welding and false welding of solder joints during processing, it may not be all problems with the welding machine at this time. After fixing, weld again, and then evaluate the effect.
From the above points, we can know that the welding effect of laser welding can be judged from many aspects. When encountering problems during the welding process, we must first make judgments according to the situation, and see where the problem occurs, so that we can deal with it faster.
