Sensors are high-precision detection instruments, which have strict requirements in aerospace production and manufacturing. Products must be strictly tested before they can be applied. There are integrated circuits and sensitive elements inside the sensor, which can be filled with inert gas or evacuated to be isolated from the outside. There are pressure resistance and air tightness requirements. In addition, there are welding process strength requirements and air leakage rate requirements, which have high requirements for welding process quality. In addition, it is required to have small deformation during welding and can not damage internal components and microcircuits.
Fiber Laser Welding Machine
Then, the traditional welding equipment such as argon tungsten arc welding, resistance welding, electron beam welding, plasma arc welding and so on can not meet this requirement. For common resistance welding, it is mainly used to weld thin process metal parts. Two electrodes clamp the surface contacted by the welder through large current, that is, the welding process is implemented through workpiece resistance heating, and the workpiece is easy to deform.
The laser welding machine does not need contact processing, and there is no tool loss and tool exchange. The moving speed of laser beam is adjustable, the energy is adjustable, and it can also be welded in various forms; Laser welding has a high degree of automation and can be controlled by computer. It has fast welding process speed and high efficiency. It is convenient to weld any complex shape; The heat affected zone is small, the material deformation is small, and there is no need for subsequent process treatment; The laser welding machine has the advantages of high production efficiency, stable and reliable processing quality and good economic and social benefits. Therefore, for precision electronic components such as sensors, laser welding machine is the best choice.
