激光焊接的优点
Merits of laser welding:

· 速度快、深度大、变形小。

· 能在室温或特殊条件下进行焊接，焊接设备装置简单。例如，激光通过电磁场，光束不会偏移；光在真空、空气及某种气体环境中均能施焊，并能通过玻璃或对光束透明的材料进行焊接。

· 可焊接难熔材料如钛、石英等，并能对异性材料施焊，效果良好。

· 可进行微型焊接。激光束经聚焦后可获得很小的光斑，且能精确定位，可应用于大批量自动化生产的微、小型工件的组焊中。

· 可焊接难以接近的部位，进行非接触远距离焊接，具有很大的灵活性。

·Fast speed, great depth and less deformation.

·Welding can be conducted in room temperature or under special conditions and the welding equipment is simple. For example, even laser goes through an electromagnetic field, the beam will not deviate. Laser can exert its function even in vacuum, air and gaseous environment, and through glass or transparent material.

·It can weld refractory materials, such as titanium, quartz, etc. and can weld anisotropic material.

·It can be used for micro-welding. After focusing, laser beam can generate very small spot and realize accurate positioning, so it may be used for assembly and welding of micro-small working pieces in mass production

.
·It can weld the part difficult to reach by means of non-contact welding at a long distance beyond, so it is very flexible.
