With the development of the laser, the laser welding technology is increasingly mature. However, in actual welding in the production process, will be because of various reasons arising from a variety of problems. How to identify the cause of the problem, how to solve quality problems appear, this is a very important part of the production process management process.

First, the quality of the welding check welding quality check. General visual inspection and destructive testing two methods. Visual inspection the name suggests, is to determine whether the welding products qualified staff based on their rich experience, but if by virtue of inspection conclusions, not fully, which requires destructive testing, confirm that ripped welding base metal . Further, the tensile tester can also be used to conduct a tensile strength test.

Secondly, based on the phenomenon of reason analysis. In general, if the welding process adverse, may the material in question, you need to check the quality of the materials to replace materials or change the laser Welding Assembly  waveform setting process conditions resolved; same position if the welding product consecutive poor welding, it is likely table and the folder has a problem; occasional welding wear and Weld phenomenon, the energy stability of the welding machine or table and fixture can check if there are problems.

Again, strengthen the welding quality assurance management. In the welding process, one should always pressure tester welding pressure testing, so that the pressure remains the same, at the same time, we should always be checked action position of the welding head; Second, we must strengthen the monitoring of current, avoid power voltage fluctuations, welding machine overload operation caused by overheating of the current output to reduce workpiece poor contact to cause the current to reduce the bad performance of the Welding Consumables; Third, it is necessary to consider changes in workpiece thickness, the thickness of the coating, metal components, to avoid welding defective products appear.
