冷媒激光焊接是将高能量密度的激光束分为两部分，使材料局部受热熔化，然后冷却凝固成一个整体。与传统焊接工艺相比，激光焊接具有以下优点：

Refrigerant laser welding is the process of dividing a high-energy density laser beam into two parts, causing the material to melt locally and then cool and solidify into a whole. Compared to traditional welding processes, laser welding has the following advantages:

1.无接触加工，焊接件无外力。

1. No contact processing, no external force on the welded parts.

2.激光能量高度集中，热冲击小，热变形小。

2. Laser energy is highly concentrated, with small thermal shock and thermal deformation.

3.可焊接高熔点、耐火材料、难熔金属，如钛合金、铝合金等。可实现异种材料之间的焊接。

3. It can weld high melting point, refractory materials, refractory metals, such as titanium alloys, aluminum alloys, etc. It can achieve welding between different materials.

4.该焊接工艺对环境无污染，可在空气中直接焊接，工艺简单。

4. This welding process has no pollution to the environment and can be directly welded in the air, making the process simple.

5.焊点小，焊缝窄，整齐美观，焊后无需处理，工艺简单。焊缝组织均匀，气孔少，缺陷少，可以减少和优化母材，焊缝的机械强度往往高于母材的机械强度。激光焊接在机械性能、耐腐蚀性和电磁性能方面优于常规焊接。

5. Small welding points, narrow welds, neat and beautiful appearance, no need for treatment after welding, and simple process. The weld seam has uniform microstructure, fewer pores, and fewer defects, which can reduce and optimize the base material. The mechanical strength of the weld seam is often higher than that of the base material. Laser welding is superior to conventional welding in terms of mechanical properties, corrosion resistance, and electromagnetic performance.

6.激光可精确控制，聚焦光斑小，定位精度高，精密加工。

6. Laser can be precisely controlled, with small focusing spot, high positioning accuracy, and precision machining.

7.易于与计算机数控系统或机械手、机器人配合，自动焊接，提高生产效率。

7. It is easy to cooperate with computer numerical control systems, robotic arms, and robots to automatically weld and improve production efficiency.

因此，利用激光焊接，具有高精度、高效率、高强度、及时性等优点，保证了质量、产量、交货期，目前，激光焊接已成为一种精密加工行业极具竞争力的加工手段，广泛应用于机械、电子、电池、航空等领域，仪器仪表等行业对工件有特殊要求，有折叠电阻点焊和密封焊。

Therefore, using laser welding has the advantages of high precision, high efficiency, high strength, and timeliness, ensuring quality, output, and delivery time. Currently, laser welding has become a highly competitive processing method in the precision processing industry, widely used in fields such as machinery, electronics, batteries, and aviation. Instruments and other industries have special requirements for workpieces, such as folding resistance spot welding and sealing welding.
