Laser welding is used in the packaging of integrated circuits and semiconductor devices in the electronic industry because of its small Heat-affected zone, small thermal stress, fast heating concentration and other advantages. Laser welding has also been widely used in the development of vacuum devices. For example, traditional welding methods are difficult to solve problems such as molybdenum coke rods and stainless steel support rings, as well as fast cathode lamp components. The elastic film wave thickness of the sensor or thermostat is 0.05-0.1mm. Laser welding has better results and is easy to weld. Pay attention to individual issues during laser welding to avoid misoperation affecting product quality. Let's take a look at the issues that need to be noted when using fiber laser welding machines.

Precautions for using fiber laser welding machines
1. Within the focusing range of the laser beam
Because the position of the weldment must be accurate, it must be within the focusing range of the laser beam in order to quickly solidify the weld bead and avoid porosity and embrittlement.

2. Welding thickness
The continuous fiber laser welding machine can weld workpieces with a thickness of 19mm. If it exceeds 19mm, a more suitable welding equipment should be selected.

3. Ionized gas
During the laser beam welding process, high energy is accumulated. If you want to prevent the weld bead from appearing again, you can use a plasma controller to eliminate ionized gas around the molten pool.

4. Welding point position
When a fixture is required for a weldment, it is necessary to ensure that the welding point hit by the laser beam is aligned with the position of the weldment.

5. Welding machine accuracy
The higher the accuracy of a laser welding machine, the better, but the higher the accuracy, the higher the cost of the laser welding machine workbench. Be sure to choose a suitable workbench for yourself. The protective gas used during laser welding can also have a significant impact on the actual welding effect.

6. Processing scope
The workpiece can be placed in a closed space, and the laser beam can be focused on a small area. It can weld a wide range of weldable materials, small and closely spaced components, and various heterogeneous materials. It can be easily controlled by digital or computer to achieve high-speed welding automation. When welding thin materials or wires, the reflow problem will not occur like that of arc welding.
Do you know what issues to pay attention to when using fiber laser welding machines? The fiber laser welding machine adopts non-contact remote welding, which can weld difficult to access parts, highlighting the great flexibility of the laser welding machine. These advantages ensure the quality of work and can also be quickly welded to accelerate work progress.
