激光焊是一种以高能量密度的激光作为焊接热源,对金属进行加热熔化,达到焊接目的焊接方法。由于激光束经透镜聚焦后光斑小、能量密度高、功率容易控制、且热源与焊件无机械接触,所以常用来焊接板厚为0.1～0.5mm的各种材质的薄板及薄壁精密小型零件。现分三方面介绍一下小功率CO_2激光焊的应用实例。仅供参考。一、硅钢带薄板的激光焊:在硅钢片的生产过程中,需要对硅钢带进行
Laser welding is a high energy density laser as the welding heat source, the metal is heated and melted, to achieve the purpose of welding welding method. As the laser beam focused by the lens spot small, high energy density, easy to control the power, and the heat source and weldment without mechanical contact, it is commonly used to weld the thickness of 0.1 ~ 0.5mm thin plates of various materials and thin-wall precision small parts . Now divided into three areas to introduce the application of small power CO_2 laser welding applications. for reference only. First, the laser welding of silicon steel sheet: In the production of silicon steel, the need for silicon steel strip
