In recent years, the global new energy vehicle industry has flourished, leading to a sharp increase in the demand for welding of high-reflective materials such as pure copper. Given that copper absorbs blue light much more efficiently than infrared light, blue laser technology has shown significant advantages in welding related materials, offering high precision, high efficiency, and flexibility, thereby providing efficient and high-quality processing solutions.     Addressing Pain Points: Blue Laser Welding Technology Balances Efficiency and Quality   The 'three-electric' system (battery, motor, and electric control) of new energy vehicles, as core components, imposes stringent requirements on welding technology during the manufacturing process. Traditional high-power infrared laser welding often faces issues such as blowholes and spatter when processing highly reflective metals like copper, gold, and aluminum. These problems not only affect the weld quality and appearance but may also contaminate and damage the optical components of the laser. Therefore, efficiently and stably welding highly reflective metal materials has become a pressing challenge in the new energy vehicle industry.   Compared to infrared lasers, blue lasers generate almost no porosity or spatter during welding and cladding processes, ensuring a smooth weld appearance and reducing the need for secondary processing. At the same time, they enable stable welding of pure copper with low-power lasers, making the process energy-efficient and environmentally friendly.     BWT Blue Laser for Welding of Purple Copper       BWT Blue Laser Welding Effect on Purple Copper   New Energy Vehicle Welding Application Case   In new energy vehicle welding applications, blue-light infrared hybrid welding technology demonstrates unique innovation. This technology combines the high absorption rate and low thermal impact characteristics of blue laser with the strong penetration and fast welding advantages of infrared laser, providing a more comprehensive solution for precision welding of high-reflective materials and dissimilar materials.   Battery System Welding   In the manufacturing process of battery systems, blue-light infrared hybrid welding technology effectively prevents spatter and the expansion of the heat-affected zone during welding, improving welding efficiency and yield, while ensuring the stability and durability of the battery modules.   Motor System Welding   For the manufacturing of flat-wire motors, blue-light infrared hybrid welding technology enables ultra-low spatter welding of copper flat wires. It offers advantages such as aesthetically pleasing welds, minimal heat-affected zones, low porosity, and high electrical conductivity and strength. This technology plays a crucial role in improving motor efficiency, reducing energy consumption, and enhancing the long-term operational stability of motors.   Electric Control System Welding   "In the electric control system, the inverter, as a core component, involves laser welding of materials such as silicon carbide transistors (SiC MOSFETs) and input/output copper busbars during its manufacturing process. Blue-light infrared hybrid welding technology enables weld joints with large fusion areas, low defect rates, and minimal spatter, providing a highly reliable solution for the secure welding of Insulated Gate Bipolar Transistor (IGBT) products.     BWT blue laser includes laser components, laser systems, and more, with a wavelength of 450nm and power ranging from 10W to 2000W, sufficiently meeting the diverse needs of various application scenarios.

As global competition in the semiconductor industry intensifies, the third-generation semiconductor material, Silicon Carbide (SiC), is increasingly favored by various industries such as new energy vehicles, electronics manufacturing, and aerospace.   Third-generation semiconductor material, Silicon Carbide (SiC)   15W Infrared Picosecond Laser: A Precision Tool for Silicon Carbide Machining   Compared to traditional silicon electronic devices, silicon carbide (SiC) has become a new semiconductor substrate material due to its multiple advantages. However, due to the significant differences in material properties between silicon and silicon carbide, existing IC fabrication processes cannot fully meet the machining requirements of silicon carbide.   Taking wafer slicing as an example, mechanical sawing, although a traditional method, proves inadequate when dealing with silicon carbide. With a Mohs hardness greater than 9, almost on par with diamond, silicon carbide not only generates a large amount of chips during the sawing process but also causes rapid wear of expensive diamond saw blades. Furthermore, the sawing speed is relatively slow, and the heat generated may adversely affect the material properties.   Silicon carbide wafer   However, the emergence of non-contact ultrashort pulse laser cutting technology has provided a new solution for silicon carbide machining. This technology can significantly reduce or eliminate edge chipping, minimize mechanical changes in the material (such as cracks, stresses, and other defects), and achieve efficient and precise cutting. At the same time, it can minimize the kerf width, greatly increasing the number of chips per wafer, thereby reducing costs.   In processes such as cutting, scribing, and thin film stripping of silicon carbide wafers, picosecond laser technology, with its unique advantages, has become the industry-recognized preferred solution and is playing an increasingly important role in the innovation of material processing technologies.   The 15W picosecond infrared laser developed by BWT is an outstanding example of this technology. This product not only possesses all of the aforementioned advantages but can also be customized according to customer needs. Its wavelength is 1064 nm, with pulse widths ranging from 10 ps to 150 ps, and repetition rates freely adjustable between 5 kHz and 1000 kHz, with average power >15 W at 50 kHz. It supports selectable pulse train numbers from 1 to 10, with M² < 1.4, divergence angle
