In the actual welding production process, but also because of various reasons and produce a variety of problems.
How to identify the causes of the problem and how to solve the quality problems, which is a very important part of the production process management.
First of all, to check the quality of welding welding quality inspection. There are two methods: visual inspection and destructive test. Visual inspection as the name suggests, is the staff according to their rich experience in welding to determine whether the product is qualified, but if by this test and as a result, is not sufficient, which requires destructive testing, which ripped the weldments for confirmation. In addition, the tensile strength of the tensile test can also be used.
Secondly, according to the phenomenon analysis. In general, if the welding process is poor, the material may be a problem, the laser welding machine needs to change the quality of the material after the inspection of the material or change the laser welding machine set the process conditions to solve.
If the same welding parts of a product for poor welding, is likely to be the work table and the fixture problems; if the occasional welding and weld, welding machine can check the energy stability of the worktable and jig or if there is a problem.
Third, strengthen the management of welding quality assurance. In the welding process, we should often use pressure tester to test the welding pressure, so that the pressure remains unchanged, at the same time, we should always check the welding head movement.
Two to strengthen the monitoring of the current, avoid the fluctuations of the supply voltage, overload operation of welding machine caused by overheating causes the current output, reduce adverse current, reduce the workpiece caused problems in laser welding machine of bad performance; three to consider the change of workpiece thickness, coating thickness, metal components, avoid bad welding the.
