随着科技的进步,激光技术在加工制造领域中的更加突出,效率高、范围广,冷媒手持激光焊在精密零件的加工应用中发挥了重要作用。激光焊接机是焊接设备中的一种,是近年来应用发展非常块的焊接方式之一,激光焊接是利用高能量的激光脉冲对工件微小区域内的局部加热,激光辐射的能量通过热传导向工件内部扩散,将工件熔化后形成特定熔池,因为激光焊接功率密度高、释放能量快,所以在加工效率方面要比传统焊接方式高的多。激光在聚焦以后,光斑细小,在焊接过程中,能够让两块材料之间的黏连度更好,不会引起材料的表面的损伤以及变形,也不用对焊缝做后期处理。
With the advancement of technology, laser technology has become more prominent in the field of processing and manufacturing, with high efficiency and wide range. Refrigerant handheld laser welding has played an important role in the processing and application of precision parts. Laser welding machine is a type of welding equipment that has been widely used and developed in recent years. Laser welding is the use of high-energy laser pulses to locally heat up small areas of the workpiece. The energy radiated by the laser is guided through heat transfer to diffuse inside the workpiece, melting the workpiece and forming a specific molten pool. Laser welding has a high power density and fast energy release, So in terms of processing efficiency, it is much higher than traditional welding methods. After focusing the laser, the light spot is small, which can improve the adhesion between two materials during the welding process, without causing damage or deformation to the surface of the material, and without the need for post processing of the weld seam.
激光焊接在电子工业中,特别是微电子精密零件中得到了广泛的应用。由于激光焊接热影响区小、加热集中迅速、热应力低,因而正在集成电路和半导体器件壳体的封装中,显示出独特的优越性,传感器或温控器中的弹性薄壁波纹片其厚度在0.05-0.1mm,采用传统焊接方法难以解决,TIG焊容易焊穿,等离子稳定性差,影响因素多而采用激光焊接效果很好,得到广泛的应用。
Laser welding has been widely used in the electronic industry, especially in precision microelectronic components. Due to the small heat affected zone, rapid heating concentration, and low thermal stress of laser welding, it has shown unique advantages in the packaging of integrated circuits and semiconductor device shells. The thickness of elastic thin-walled corrugated sheets in sensors or temperature controllers ranges from 0.05 to 0.1mm, which is difficult to solve using traditional welding methods. TIG welding is easy to weld through, with poor plasma stability and multiple influencing factors. Therefore, laser welding has good results and has been widely used.
