1、高功率密度与小热影响区

　　1. High power density and small heat affected zone

　　激光焊接中的激光功率密度可达10^510^7 W/cm?。由于激光束的聚焦效果，材料的热影响区非常窄，产生的变形也小。这使得激光焊接特别适合于焊接和微细焊接，能够实现高质量的焊接接头。

　　The laser power density in laser welding can reach 10 ^ 5 to 10 ^ 7 W/cm?. Due to the focusing effect of the laser beam, the heat affected zone of the material is very narrow, and the deformation generated is also small. This makes laser welding particularly suitable for welding and micro welding, enabling high-quality welded joints.

　　2、厚件焊接与不开坡口焊接

　　2. Thick piece welding and non beveled welding

　　激光焊接可以在不需要坡口的情况下直接焊接厚件，能够获得深宽比大的焊缝。例如，单道焊接钢板的厚度已可以达到50mm。这种特性简化了焊接过程并提升了效率。

　　Laser welding can directly weld thick parts without the need for grooves, and can obtain welds with a large aspect ratio. For example, the thickness of a single welded steel plate can reach 50mm. This feature simplifies the welding process and improves efficiency.

　　3、难焊材料的焊接能力

　　3. Welding ability of difficult to weld materials

　　激光焊接适用于传统焊接方法难以处理的材料，包括难熔金属、热敏感性强的金属，以及热物理性能差异悬殊的材料。此外，激光焊接也能用于非金属材料，如陶瓷和有机玻璃等。

　　Laser welding is suitable for materials that are difficult to process using traditional welding methods, including refractory metals, metals with strong thermal sensitivity, and materials with vastly different thermal and physical properties. In addition, laser welding can also be used for non-metallic materials such as ceramics and organic glass.

　　4、密闭容器内焊接

　　4. Welding inside a sealed container

　　激光束可以穿过透明介质焊接密闭容器内的工件，适用于在玻璃封闭容器中焊接如铍合金等剧毒材料。这一特性增强了激光焊接在特种环境中的应用能力。

　　The laser beam can pass through transparent media to weld workpieces inside sealed containers, and is suitable for welding highly toxic materials such as beryllium alloy in glass sealed containers. This feature enhances the application capability of laser welding in special environments.

　　5、光束传输与反射

　　5. Beam transmission and reflection

　　激光焊接通过反射镜可以将激光束送达传统焊接方法无法到达的部位。YAG激光器（波长1.06μm）还可以通过光纤进行传输，进一步提高了激光焊接的可达性。

　　Laser welding can deliver laser beams to areas that traditional welding methods cannot reach through mirrors. YAG laser (wavelength 1.06 μ m) can also be transmitted through optical fibers, further improving the accessibility of laser welding.

　　6、免电磁干扰

　　6. Free from electromagnetic interference

　　激光束不受电磁干扰，没有磁偏吹现象，这使得激光焊接特别适合用于磁性材料的焊接。

　　The laser beam is not affected by electromagnetic interference and there is no magnetic bias blowing phenomenon, which makes laser welding particularly suitable for welding magnetic materials.

　　7、操作简便与性

　　7. Easy to operate and safe

　　激光焊接无需真空室，不产生X射线，因此观察和对中过程更加便捷、。

　　Laser welding does not require a vacuum chamber and does not produce X-rays, making the observation and alignment process more convenient and safe.
