Sensors are high-precision detection instruments that have strict requirements in aerospace production and manufacturing, and products must undergo rigorous testing before they can be applied. The sensor has integrated circuits and sensitive components inside, which can be filled with inert gas or evacuated to isolate from the outside. It has requirements for pressure resistance and airtightness, as well as welding process strength and gas leakage rate. It has high requirements for welding process quality, and requires minimal deformation during the welding process, and cannot damage internal components and microcircuits.
Traditional welding equipment such as tungsten argon arc welding, resistance welding, electron beam welding, plasma arc welding, etc. cannot meet this requirement at all. For common resistance welding, it is mainly used to weld thin process metal parts. Two electrodes are clamped to melt the surface of the welded part that is in contact with the electrode through a large current, which is achieved by heating the workpiece resistance. The workpiece is prone to deformation.
The fiber laser welding machine does not require contact processing, and there is no tool loss or tool exchange. The laser beam can move at an adjustable speed, with adjustable energy, and can also be welded and processed in various forms.
Fiber laser welding machine has a high degree of automation and can be controlled by computers. The welding process is fast and efficient, making it easy to weld any complex shape; The Heat-affected zone is small, and the material deformation is small, so there is no need for subsequent processing.
Fiber laser welding machine have high production efficiency, stable and reliable processing quality, and good economic and social benefits. So for precision electronic components such as sensors, using a laser welding machine for welding process is the best choice.
