What are the reasons for the unstable welding of laser welding machines

Why is the welding of laser welding machines not firm
1. Surface contamination of materials
Generally speaking, when using a laser welding machine for welding processing, attention should be paid to whether there is dirt on the surface of the material. If materials with dirt are placed in the welding area, the surface of the material will not crystallize properly or the crystallization will be insufficient, which is one of the factors directly affecting the instability of the laser welding machine.

2. Welding speed is too fast
Users often mistakenly believe that the faster the welding speed, the faster the production, and the better the product when using laser welding machines. In fact, when a laser welding machine is used for material processing, the longer the processing time between the laser and the workpiece, the more complete the welding, not necessarily the faster; On the contrary, the faster.

3. Mismatch between material and welding power
The power of laser welding machines is not applicable to all materials. The power used for welding different materials varies. If the user uses low power, the welded material is not firm; For some highly reactive materials, we can increase the welding power and slow down the welding speed and other welding process parameters.

4. Workbench and Fixtures
The workbench and fixtures are used to secure materials. If the material is not firmly fixed enough, successful welding may not be possible, resulting in poor welding and missing welding. For example, nanosecond laser welding equipment will require two welded parts to be completely attached, otherwise it is easy to have virtual welding. And for welding that is difficult, we need to customize tooling fixtures to meet the welding needs.
