It can be divided into three categories. The first type: Thermal conductivity welding, refers to energy density less than 105w/cm² welding method. It is characterized by wide and shallow welding pool section. The second type: Deep penetration welding, refers to energy density at 105w-107w/cm² welding method. It is characterized by a narrow and deep keyhole in the welded pool section welding. The third type: MOPA laser welding, using the characteristics of high peak and short pulse of MOPA laser, This enables MOPA laser welding to be used for welding between two or more dissimilar metals with different melting points. It is characterized by sawtooth welding pool section. It also can be call "micro keyhole welding".
laser come out from the laser source and passes though the scan head and lens or collimeter and focusing system or other optical equipment. Then the surface of the material will be irradiated by focused laser beam. The upper and lower layers are fuse together because of the irradiated from the laser(The actual welding is much more complicated and this is just a brief introduction).
Application industry: manufacturing and industrial, medical, 3 C Electronics (e.g. electronic cigarette), automotive industry(e.g. cellpacking), Jewelry and etc.

Hair-pins Welding
Compared with the traditional round enameled wire winding, the hair-pin winding has been widely used in the new energy vehicle motor due to its neat arrangement of copper wires and high conversion rate.
1. The sample after welding should be free of thermal damage.2. The welding seam must be pore-free. 3. The connection area should be > 120%.
