At present, the field of science and technology is developing very rapidly. With the continuous development of science and technology, intelligent industrialization has gradually formed. With the development of laser welding technology, the technology of laser welding machine is also becoming more and more mature, and the application scope of laser welding industry continues to expand. However, in the actual production process of welding machine, there will also be various problems due to various reasons. So how to control the quality of laser welding machine?
1. Check the quality of the welding machine. Generally, there are two methods: visual inspection and destructive inspection. Visual inspection, as the name suggests, refers to the staff judging whether the welding machine products are qualified according to their rich work experience. However, if it is not sufficient to draw a conclusion based on this inspection, it requires destructive inspection, that is, tearing up the base metal of the welding machine for confirmation. In addition, the tensile strength can also be tested with a tensile tester.
2. Analyze the causes according to the phenomenon. Generally speaking, if the welding machine has poor processing, there may be material problems, which need to be solved by changing the material or changing the waveform of the laser welding machine after checking the material quality; If the same part of the welding machine product has continuous welding machine defects, it is likely that there is a problem with the workbench and fixture; If there is welding penetration and faulty welding occasionally, you can check the energy stability of the welding machine or whether there is a problem with the workbench and fixture.
3. Strengthen the quality assurance management of welding machines. In the process of welding machine, firstly, the pressure of welding machine should be tested with pressure tester to keep the pressure unchanged, and at the same time, the action condition of welding machine head should be checked frequently; Second, we should strengthen the monitoring of current to avoid the fluctuation of power supply voltage, overheating caused by overload operation of welding machine, reduction of current output caused by poor contact of workpiece, poor performance of welding machine and other problems; Third, the changes of workpiece thickness, coating thickness, metal composition, etc. should be considered to avoid the occurrence of defective products of the welding machine.
