以激光热源为主体，对锡料填充熔融固化达到连接、导通、加固的工艺效果。优点：非接触，无静电，无空间限制，耗材少，速度快。

The laser heat source is used as the main body to fill and melt the tin material to achieve the process effect of connection, conduction and reinforcement.

Advantages: non-contact, no static electricity, no space limitation, less consumables and fast speed.

应用中，需要其中一种材料能够透过激光，而另一种材料要吸收激光或者材料表面涂层吸收激光，两种材料需要连接的部分在压力作用下，随着激光束移动形成材料间的连接带。优点：牢固，密封，易控制，可异种材料焊接。

In applications, one of the materials needs to be able to transmit the laser, and the other material must absorb the laser or the surface coating of the material must absorb the laser. The part of the two materials that needs to be connected under pressure acts as the laser beam moves to form a connecting band between the materials.

Advantages: firm, sealed, easy to control, welding of dissimilar materials.

激光沿着需要连接的轨迹将板材熔化，使两块薄板连接处熔化结合，冷却后形成焊缝。优点：熔池稳定，焊缝平滑。

The laser melts the plate along the track to be connected, melts and joins the joints of the two thin plates, and forms a weld after cooling.

Advantages: stable molten pool and smooth weld.

激光是金属部件进行淬火的理想热源，可以在保持基材的冶金性能不变的前提下提升零件的耐磨性。激光可以在不使得其他区域铁素体发生相变的情况下，灵活地实现部分区域淬火。优点： 激光加热速度快，热影响区小，变形量极小，高效、清洁。

Laser is an ideal heat source for quenching metal parts. It can improve the wear resistance of parts while maintaining the metallurgical properties of the substrate. The laser can flexibly realize the quenching of some regions without causing ferrite phase transformation in other regions.

Advantages: Fast laser heating speed, small heat affected area, minimal deformation, high efficiency and clean.
