Fiber laser welding machine makes sensor welding more convenient

The sensor is a high-precision testing instrument, which has strict requirements in aerospace production and manufacturing. Products must be strictly tested before they can be used. There are integrated circuits and sensitive components inside the sensor, which can be filled with inert gas or evacuated to isolate from the outside. It has requirements for pressure resistance and air tightness. There are also requirements for welding process strength and air leakage rate, and high requirements for welding process quality. The welding process requires small deformation and no damage to internal components and microcircuits.

Then, traditional welding equipment such as argon tungsten arc welding, resistance welding, electron beam welding, plasma arc welding, etc. simply cannot meet this requirement. For common resistance welding, it is mainly used to weld thin process metal parts. The two electrodes clamp the workpiece to be welded and melt the surface of the electrode contact by a large current, that is, the welding process is implemented through resistance heating of the workpiece, and the workpiece is easily deformed.

The laser welding machine does not require contact processing, and there is no tool loss and tool replacement. The moving speed of the laser beam can be adjusted, the energy can be adjusted, and various forms of welding can be performed; the laser welding has a high degree of automation, which can be controlled by a computer, the welding process is fast, and the efficiency is high, which can facilitate the welding of any complicated shape; heat influence The area is small, the material deformation is small, and subsequent process processing is not required; the laser welding machine has 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 for welding process.
