In large-scale production, automatic laser welding machines often require the use of automatic workbenches to improve production efficiency, so different workbenches can also have a significant impact on the welding effect. In actual welding production, various problems may arise. How to determine the causes of problems and how to solve them is also a very important part of production process management.
In theory, the higher the specific selection accuracy of the workbench, the better; But the higher the accuracy, the higher the production cost of the workbench, and it is necessary to choose a suitable workbench. In addition, whether to use shielding gas or choose different shielding gases can also have a significant impact on the actual welding effect. The relevant characteristics of the workbench mainly consider the following aspects:
Movement characteristics: movement accuracy, repeatability, and movement speed.
Fixture features: fixture accuracy, heat dissipation ability, clamping force, and convenience.
Auxiliary gas: shape, aperture, gas type, flow, pressure, angle, distance.
Generally speaking, poor welding of the same part of the welding product is likely due to issues with the workbench and fixture. At this point, it is necessary to start solving the problem from the fixture and workbench. If different batches of incoming materials result in poor welding processing, it may be a problem with the incoming materials. It is necessary to check and replace the incoming materials or change the process conditions of the laser welding machine waveform settings. If occasional welding penetration and virtual welding phenomena occur, the energy stability of the welding machine or whether there are problems with the workbench and fixture can be checked.
In short, the quality assurance of automatic laser welding machine welding products is a very complex system engineering, and every small step will affect the product's excellent rate. This requires users to summarize different situations and find welding quality control methods that are suitable for their own product characteristics.
