II. Well-known Domestic Brands

1. Han's Laser

 A globally leading laser manufacturing company with vertical integration capabilities. Its laser welding machines can achieve micron-level high-precision welding, exhibiting excellent adaptability to complex shapes and micro-components, producing fine and uniform welds.

2. HGTECH

One of the leading companies in China's laser industry, its 3D five-axis laser welding equipment achieves a positioning accuracy of ±0.03mm and a welding speed of up to 43 seconds per unit in automotive body-in-white welding, breaking the long-term monopoly of international brands.

3. Qilin Laser

 A leading company in China's laser welding industry, it pioneered the world's first dual-pendulum handheld welding and air-cooled fish-scale welding technologies and has established deep cooperative relationships with teams from universities such as Huazhong University of Science and Technology. The company has an 8000m² production base and a 2000m² Class 1000 cleanroom, possessing complete independent R&D and production capabilities, with products covering high-end fields such as new energy and automotive manufacturing.

Regarding representative equipment, Qilin Laser has built a complete product matrix. Its handheld laser welding series focuses on lightweight and intelligent design. For example, the newly launched DWS20 single-pendulum handheld laser welding gun weighs only 0.3kg, and the BWS20 dual-pendulum handheld laser welding gun weighs only 0.4kg, requiring no professional welders to operate, significantly reducing enterprise labor costs.

The newly launched M-series air-cooled handheld laser welding machine integrates five welding modes: pulse, continuous, fish scale, line segment, and riveting. It not only meets the requirements for preventing burn-through in thin plates but also solves the problem of insufficient filler in thick plates through a double-swing, double-wire process, achieving single-sided welding with double-sided forming. With a power of up to 1600W and a heat dissipation capacity five times that of traditional solutions, it ensures stability in mass production of sheet metal chassis, kitchen and bathroom equipment, and new energy battery modules, making it suitable for mixed-use applications requiring both precision welding and handling heavy-duty thick plates.

The newly launched F-series air-cooled handheld laser welding machine features a self-developed air-cooled laser and a 44-copper-pipe intelligent heat dissipation system. It can operate continuously 24/7 in a wide temperature range of -40℃ to 45℃ without an external chiller, making it particularly suitable for outdoor high-altitude and confined space welding scenarios. This series comes standard with a double-swing welding torch, combined with spot shaping technology, easily producing uniform and dense fish scale welds up to 12mm wide. It also features a built-in fully closed-loop intelligent welding system, allowing beginners to easily adjust parameters with a single click by selecting the material thickness.

4. UW Laser

Possesses significant advantages in the welding of new energy power batteries. Its laser welding equipment utilizes multi-wavelength coaxial composite welding technology, solving welding challenges for highly reflective materials such as copper and aluminum, with welding speeds reaching up to 300mm/s.

5. ChuTian Laser

Founded in 1993, it is one of the earliest private laser companies in China. Its laser welding machines boast advantages such as high aspect ratio, small weld seams, and small heat-affected zones. Employing a laser power feedback control system, it ensures stable energy output.

In the future, it is believed that as laser technology continues to mature, more stable, durable, intelligent, and versatile welding equipment will become a crucial support for the upgrading of the manufacturing industry. Thank you for reading, see you next time.
