Optical fiber laser welding machine makes sensor welding more convenient
Release time:2022.12.16
The sensor is a high-precision testing instrument, which has strict requirements in aerospace production and manufacturing, and the products can only be applied after strict testing. There are integrated circuits and sensitive elements inside the sensor, which can be filled with inert gas or evacuated to isolate it from the outside. There are pressure resistance and gas tightness requirements. There are also requirements for welding process strength and gas leakage rate. The requirements for welding process quality are high, and the deformation during welding is required to be small, and the internal elements and microcircuits cannot be damaged

Then, traditional welding equipment such as argon tungsten arc welding, resistance welding, electron beam welding, plasma arc welding, etc. can not meet this requirement. For common resistance welding, it is mainly used to weld thin process metal parts. Two electrodes clamp the surface of the welding part that is contacted by the electrode through a large current, that is, the welding process is carried out by heating the workpiece resistance, and the workpiece is easy to deform.
The laser welding machine does not need to contact processing, tool loss and tool replacement. The moving speed and energy of the laser beam can be adjusted, and it can also be welded in various forms; Laser welding has a high degree of automation, which can be controlled by computer. The welding process is fast, efficient and convenient for welding of any complex shape; The heat affected zone is small, the material deformation is small, and no subsequent process treatment is required; Laser welding machine has high production efficiency, stable and reliable processing quality, and good economic and social benefits. Therefore, laser welding machine is the best choice for precision electronic components such as sensors.
